ww2 German Tanks Nazi Germany (1943)
Tank Hunter – 494 built

As the German armored forces advanced on all fronts in 1940 and 1941, they encountered many different enemy tank types that were almost immune to the guns of their Panzers. In France, these were the Char B1 bis and the British Matildas (both the A11 and A12 Matilda). When the Germans met the first Matildas at Arras, it was an unpleasant shock, although one that was overcome. In the Soviet Union were the famous T-34 and heavy KV-series, and in Africa, again, (in larger numbers) the A12 Matilda tank. While they were able to defeat these by various means, the Germans were pressed to find a better way to combat these threats.
The newly developed towed anti-tank guns (like the PaK 40, built in 1942 and the much stronger PaK 43 in 1943) could efficiently destroy these tanks, but they were not suitable for offensive operations due to their heavy weight. A logical solution was to try to mount these towed anti-tank guns on a tank chassis and thus solve problems of mobility, and so the new Panzerjäger’s were born.
These new vehicles followed a similar pattern: most were open-topped, with limited traverse, and thin armor. They were, though, armed with an effective anti-tank gun, and usually with one machine gun. They were also cheap and easier to build than ordinary Panzers. Panzerjäger’s were, in essence, improvised and temporary solutions, but effective ones nevertheless. Just as the name suggests, they were designed to hunt down enemy tanks at long range on open fields. Their primary mission was to engage enemy tanks and to act as fire support at long range from carefully selected combat positions, usually on the flanks.
In 1943, the development of an anti-tank gun version of the FlaK 41 was completed. As, at that time, there were no dedicated chassis’ designed to carry this gun and in order to increase the mobility of the towed version, a temporary self-propelled solution was needed. From this need, a new vehicle, well known as the Nashorn (Rhinoceros), would be designed and built based on a modified Panzer III/IV tank chassis.

History

The story of the Nashorn began in June 1942, when Hitler demanded that a new anti-tank gun should be developed based on the 88 mm Flak 41. Two famous German weapon manufacturers, the firms of Krupp and Rheinmetall, were tasked with its development. It was estimated that the development and production of some 300 to 500 guns would be ready by mid-1943. For this reason, it was proposed to also develop different towed carriages and self-propelled designs.
It was quickly noted that the new Selbstfahrlafette (self-propelled chassis) could not be completed by the time the new 88 mm gun was ready and so a new solution was needed to get the new weapon on the battlefield faster. In a Wa Pruef meeting held on 28th July 1943, it was decided to speed up the project by using already existing production capacities. An order was placed to the firm of Alkett-Borsigwalde to design and build a self-propelled chassis by using different components of the Panzer III and IV. Alkett was quick to make a soft steel metal prototype which was presented to Hitler in early October 1942. The new chassis was to be used for two different projects, one armed with the 88 mm gun and the second armed with 15 cm s.F.H 43 long-range artillery gun. Hitler was impressed with both designs and ordered a production run of 200 vehicles (100 of each).

Name

There were several different military designations for this vehicle, such as: Sfl. auf PzKpfw. III/IV Fahrgestell Hornisse mitt 8.8 cm PaK 43 from January 1943, Panzerjager III/IV “Hornisse” für 8.8 cm PaK 43/1 (Sd.Kfz.164) from August 1943, 8.8 cm PaK 43/1 Sfl. “Nashorn” from September 1944 and 8.8 cm PaK 43/1 auf Fgst.Pz.Kpfw.III und IV (Sf) Sd.Kfz. 164.
Early on, it was also simply known as the Hornisse (Hornet). In late 1943, Hitler ordered to change the nickname to Nashorn (Rhinoceros). For the sake of simplicity, this article will use the Nashorn name.

Specification

Despite its close resemblance to the ordinary Panzer IV tank chassis, the Nashorn was actually designed and built by combining elements and components from both the Panzer III and Panzer IV. The Nashorn hull was mostly the same as that of the Panzer IV, but with the width of a Panzer III. Most of the components of the drivetrain were taken also taken from the Panzer III, including the two front drive sprockets, the transmission, and the steering unit with the drive shaft. The suspension was taken directly from the Panzer IV and it consisted of eight small road wheels on each side, suspended in pairs by leaf-spring units, a rear idler and four return rollers on each side. The tracks were also taken from the Panzer IV, with 108 links in total. The distance between the rear road wheels and the idler was somewhat increased during the production. The Nashorn could be equipped with different track types depending on the combat need and availability, like the Winterketten or Osketten for example. Despite being produced up the end of the war, the number of return rollers was never reduced to three (per side) on Nashorns, in contrast to other Panzer IV-based based vehicles.
The engine compartment was moved to the vehicle’s reinforced center. This was mostly done in order to create enough room for the gun and the crew to operate efficiently at the back. The engine was the Maybach HL 120 TRM, taken together with the radiators, cooling fans, and muffler from the Panzer IV. The engine performance was more or less the same as on the Panzer IV, giving a maximum speed of 40 km/h. Due to the central engine position, in order to avoid engine overheating, two (on both lower hull sides) rectangular shape cooling ports were added. In addition, the Nashorn had a crew interior heater system despite being open-topped. The engine was started by using an electrical starter but, depending on the situation, could be started manually by a crank located in the crew compartment. The fuel load was around 600 l (or 470 l depending on the source) held in two fuel tanks placed below the fighting compartment. With these, the Nashorn had an operational range of 260 km (around 130 km cross country). The Nashorn also had a problem with frequent breakdowns of the engine, mostly due to overheating, which was never fully solved.

The front of the Nashorn was covered by a well-angled and simple armored plate. The driver compartment on the front left side was fully protected. The driver had three observation hatches, one for the front, and one on each side. On top of the driver’s enclosed compartment was a round hatch. The rear crew compartment was protected by armored slats, but was open from the top. To the rear was a two-part door, through which the crew members could access their positions. The new superstructure (both the front and the rear) had a very simple design but the armor was very light. The maximum armor was 30 mm around the driver compartment and the frontal glacis, the hull sides and rear were 20 mm and the bottom 10 mm. The superstructure armor was only 10 mm on all sides, the top was open. Originally, it was planned that the armor would be 20 mm on the superstructure and 50 mm in the hull, but these plans were dropped in order to save weight. The new superstructure was built by Witkowitzer Bergütte und Geschutzwerke from Witkowice Silesia, all being completed by the end of 1943.
The rear part of the vehicle was the combat compartment, which offered the crew more working space. Crew-necessary equipment, instruments, personal belongings, weapons and ammunition were also stored here. Most of these were stored on the compartment sides. On the right side were the mountings for an MG-34 machine gun (with 600 rounds of ammunition) and spare parts, gas mask box, radio equipment, and 88 mm round storage cases. On the opposite side there was another 88 mm round storage case, MG-34 mounting, signal pistol, hot air inlets from the engine, a lever for releasing the gun lock, and the gun sights mount with its box. At the rear were usually held the crew personal weapons (MP-38 for example) and ammunition. Other equipment that was stored included the tarpaulin for protection from bad weather, first aid kits, fire extinguishers, and poles for determination of the direction of the firing axis (these were removed after March 1943) etc.
The crew consisted of five members, the commander, the gunner, the radio operator, the loader, and the driver. The driver and the radio operator were stationed in the front hull as on the Panzer IV (driver to the left and radio operator right) and were the only crew members that were fully protected. The driver controlled the vehicle by using levers and pedals that were positioned in front of the driver. Behind them, in the open combat compartment, were the remaining crew members. The gunner was stationed to the left of the gun, while the commander and the loader were behind him. For the crew, two internally mounted periscopes could be added for viewing the surrounding without being exposed to enemy fire.
In the case of Abteilung Stab Kompanie, additional radio equipment was provided (Fu 8) beside the standard radio. This caused some problems for the radio operator, as he was physically unable, due to different positions of the radio sets, to operate them both. The Nashorn equipped units often requested that an additional radio operator be provided to the Abteilung Stab. It is not clear if this was ever implemented, as the sources do not give more information on this matter.

The 88 mm PaK 43/41

During the war, Germans produced two anti-tank gun versions based on the 88 mm Flak 41. The first one was the PaK 43, which was mounted on a four-wheel carriage, and the second was the PaK 43/41 (also known as PaK 43/1 in some sources), placed on a mount with components from a few different artillery pieces (wheels from 15 cm s.FH.18 and the split trail legs from 10.5 cm l.FH.18). The PaK 43/41 used a horizontal sliding block mechanism, while the Pak 43 had a vertical one. The PaK 43/41 was an effective anti-tank gun, being able to take out all of the Allied tanks, but was also too heavy. It was jokingly known by its crews as the ‘barn door’ (Scheunentor).

The PaK 43/41 was chosen as the main armament of the Nashorn. The installation was done by placing the gun mount above the central engine compartment. During production, there were plans to replace it with the Pak 43 version, but this was never implemented. The new gun was more or less the same as the towed version, with minor modifications in order to install it inside a vehicle. The 88 mm gun had a traverse of 30° and elevation of -5° to +20° (or -5° to +35° depending on the source). The recoil cylinder was located under and the recuperator above the gun. There were also two counterbalance cylinders (one on each side).
For direct fire, the Zieleinrichtung 43 SVo (with 3x magnification and 8-degree field of view) gunsight was used. For indirect fire, it was the Zieleinrichtung 34. These two sights were installed on the first series of 50 vehicles, after which the Zieleinrichtung 37 (with Sfl. Z.F.1a periscope) was used. With the installation of the new gun sight, the open slot in the gun shield where the old sight was positioned was closed.
The Nashorn 88 mm gun could fire four different types of ammunition:

  • 88 mm Pzgr.39 (with a weight of 10 kg and muzzle velocity of 1000 m/s) AP round
  • 88 mm Sprgr. (with a weight of 9.4 kg and muzzle velocity of 700 m/s) HE round with a maximum range of 17,500 m
  • 88 mm Pzgr.40 (with a weight of 7.3 kg and muzzle velocity of 1,140 m/s), a tungsten-cored round, but it was rarely deployed due to general lack of this metal
  • 88 mm Gr.HL (with a weight of 7.62 kg and muzzle velocity of 600 m/s) hollow charge round


A loader of a Nashorn is preparing to load a new round into the gun. Despite the relatively spacious rear fighting compartment, the total ammunition load was small. Source.
When using the standard AP round, the gun could penetrate 182 mm of armor sloped at 30° at a range of 500 m. At, 1,000 m, this dropped to 167 and at 2000 m to 139 mm. The rare tungsten round, at the same ranges and angle, could penetrate 226 mm, 162 mm and 136 mm. The hollow charge round could penetrate 90 mm of armor inclined at 30° at any range.
Despite the larger crew compartment, due to the large ammunition size, only a small number of rounds was carried inside the Nashorn. The ammunition was stored in two (one on each side) ammunition bins with 16 rounds in total, with an additional 24 round that could be stored on the floor. Due to the small ammo stowage, a constant supply of ammunition was to be provided by using Maultier half-tracks, which could not be always successfully achieved on the battlefield. It is plausible that the crews would have stored additional rounds in any available free space inside the vehicle. There were some problems with a general lack of ammunition, which could not be produced in sufficient numbers.
Originally, early vehicles were equipped with the same travel lock as on the Hummel, probably in order to simplify production. This travel lock did the job of holding the gun in position, but it had a drawback. In order to free the gun, one of the crew had to go out and manually remove the bolt that held it in place. While this is not a big issue for the Hummel, a vehicle that was usually providing fire support (depending on the combat situation) kilometers away from the main front line, for the Nashorn, which was far closer to the front, this was a big issue. One of the crew members had to expose himself to possible enemy fire and the time lost could prove to be fatal The gun lock was later replaced with an improved one that could be controlled from inside the vehicle. There was also a rear gun position travel lock, but its use was discarded in later models. The gun shield would see some changes in design to better fit with the superstructure sidewalls.

Production

Two firms were selected for the production of the Nashorn: Alkett from Berlin and Stahlindustrie from Duisburg. Alkett was charged with series production of 10 vehicles in January, 20 in February, 30 in March and then at a rate of 30 vehicles per month until March 1944, producing a total of 420 vehicles. Stahlindustrie was tasked with a smaller production series of 5 in May, 10 in June, 15 in July and then 15 per month (also until March 1944), with a total production of only 150 vehicles.
Like nearly all German production plans, the one for the Nashorn did not go as intended. In early February, in a meeting between Hitler and Speer, it was decided to reduce the monthly production of the Nashorn from 45 to only 20 vehicles. This was done for two reasons. Firstly, the Nashorn was seen as a temporary solution and never intended for large mass production. Secondly, it was intended to increase the production of the more important Hummel SPG. Due to a lack of main guns, Stahlindustrie was not able to commence Nashorn production and instead began producing Hummels. In July 1943, the production numbers were once again changed to 500 vehicles. Plans for changing the main armament to a modified 88 mm PaK 43 were abandoned in the hope of increasing the numbers of PaK 43/41 guns available, in order to build all the 500 planned vehicles. Due to the Allied bombing campaign in late 1943, the production of the 88 mm Pak was significantly slowed down, which also influenced the production of Nashorn. By 4th November 1943, some 284 vehicles were completed, while the remaining 216 were to be built in a series of 40 vehicles until March 1944, with the last 16 the following month.
In late November, there were even talks of stopping the Nashorn production, but it was decided to go on with it until the Jagdpanther was ready in 1944. Also in November, Alkett was bombed, so Nashorn production had to be moved to Deutsche Eisenwerke A.G. which had assembly factories located in Teplitz-Schönau and Duisburg. By May 1944, Alkett stopped the production of the Nashorn and Deutsche Eisenwerke were tasked with series production of 100 vehicles from April to June 1944. The order was changed to 130 from April to September, but due to many delays (lack of engines, transmissions, etc.), the production continued at a slower pace until the end of the war. In total, 494 vehicles (chassis number 310001-310494) were built, with 345 in 1943, 133 in 1944 and the last 16 in 1945.
In March 1945, there were discussions to reuse Hummel chassis’ and re-equip them with 88 mm guns, but due to material shortages, the need of the mobile artillery and the close end of the war, nothing came of this proposal.

Production Changes

As the Nashorn was considered only a temporary solution, the Germans did not introduce many modifications during its production run. It would only receive these modifications in order to simplify construction. Because of these changes, there were some minor differences between the early and late produced vehicles. Officially, there was never a special designation change in order to identify the early or late produced vehicles.
The early production vehicles had two front Bosch headlights, rear fitted mufflers and two front-mounted wheels. The later built vehicles had only one headlight, on the vehicle’s left side. The rear exhaust muffler was removed and replaced with exhaust pipes located on both of the vehicle’s sides. The front two wheels were moved to the rear and the rear mudguards were removed.
The early vehicles were equipped with the Hummel travel lock, but later models would have a new travel lock, equipped with a very simple wire release system which could be used from inside the vehicle.

The rear mudguards were removed on later-built vehicles. There were also minor changes in the design of the driver’s observation hatch cover. Two brake vents were placed in the lower part of the angled front armor. During production, the size and design of the brake vents was slightly changed.
A hole with a movable armor cover was added to the lower-left of the hull. Its purpose was to help with warming the engine coolant with a blowtorch in cold weather. Two towing hooks were welded to the rear hull.

Interior differences were not recorded, but there is always a possibility that there were some minor changes. While the Hummel received a specially designed front hull crew compartment (driver and radio operator), this was never implemented on the Nashorn.
Other changes were connected to the running gear of the Panzer III and IV. The early production vehicles had drive sprocket taken from the Panzer III Ausf. E (type Z.W.38). The return rollers and the idlers were taken from Panzer IV Ausf.D and F. Later produced vehicles used the drive sprocket taken from Panzer III Ausf.H (or Ausf.J depending on the source). There is evidence that a number of vehicles were built using a combination of these components.
There were also field modifications. While most were minor, like adding an extra tool or supply box, others include additional frontal armor plates in hope of increasing the armor thickness.

Organization

The Germans originally planned to use the Nashorn equip the 10 vehicle-strong Kompanie in the Panzerjäger Abteilung of the Panzer Divisions. This was never implemented. Instead, Nashorns were given to independent Schwere (Heeres) Panzerjäger Abteilung (heavy anti-tank battalions) which were then, depending on the operational needs, temporarily attached to different Armee Korps. This was a standard German war practice with other rare armored vehicles (like Tiger or Ferdinands for example), who were also grouped into independent units. Only Corps and Army Headquarters had the authority to give such orders.
These Schwere Panzerjäger Abteilung would be composed of 45 vehicles, divided into three Kompanie (companies) with 14 Nashorn each and a Stabskompanie with 3 vehicles. The Kompanies were again divided into Zuge (platoons), each with 4 vehicles and with 2 in the Command Platoon.

In combat

During the war, several Schwere Panzerjäger Abteilung (short s.Pz.Jg.Abt) would be formed, including 560, 655, 525, 93, 88, 664, 519 and 424. Other smaller units were formed, including the Schwere Panzerjäger Ersatz 43 und Asbuildung Abteilung, s.Pz.Jg. Kompanie 669 and Panzerkompanie Kummersdorf. The only units to receive Nashorns were the 1st Panzer Division and possibly the Das Reich Division.

Schwere Panzerjäger Abteilung 560

The forming of s.Pz.Jg.Abt 560 and equipping it with the Nashorn was a slow process. The first six vehicles were received in February, followed by 24 in March, and the last 15 in May 1943. In preparation for the coming Kursk offensive, s.H.Pz.Jg.Abt 560 was to be transported to Kharkiv in late April 1943. By the beginning of May 1943, the transportation of the unit was almost complete. In June, it was part of the Panzer Gruppe “Kempf”, but due to many mechanical problems, this unit was not ready for combat. While this unit did not see action during the battle for Kursk, it was busy defending the XXXXII Armee Korps’ (In September renamed into the 8th Armee) flanks from July onwards.

This vehicle had an early type travel lock that had to be released from outside. This vehicle belonged to s.Pz.Jg.Abt 560. It is on a train, possibly headed for the Eastern front. Source.
Throughout August, this unit also supported the 39th, 161st, and 282nd Infanterie Divisions. During this time, 14 vehicles were lost. s.Pz.Jg.Abt 560 would be used mostly in defending actions against Soviet attacks until the end of 1943.
Thanks to constant reinforcement (with 5 vehicles in September, October, November, and 4 in February 1944), s.Pz.Jg.Abt 560 managed to maintain almost full combat strength throughout 1943, although not all the vehicle were always operational. For example, on 31st October 1943, there were 39 vehicles in the unit, with only 8 operational and the remaining in various state of repair. By the end of 1943, s.Pz.Jg.Abt 560 reported having destroyed around 251 enemy tanks.
In January 1944, s.Pz.Jg.Abt 560 participated in the German defense of the city of Kirovograd (currently known as Kropyvnytskyi). In early February, this unit began a slow withdrawal toward Mielau in order to be requipped with the new Jagdpanther. By March, it was still engaged on the Eastern front under the LVII Pz.Korps, losing 16 Nashorn. By this time, s.Pz.Jg.Abt 560 had only 4 operational and 10 non-operational vehicles remaining. In late April 1944, the withdrawal was completed and s.Pz.Jg.Abt 560 was moved to Mielau.

Schwere Panzerjäger Abteilung 655

Another unit equipped with Nashorns was s.Pz.Jg.Abt “Stalingrad”. In April 1943, this unit was renamed s.Pz.Jg.Abt 655. For the creation of this unit, the remaining elements from Panzerjäger Abteilungen 521, 611, and 670 were used. It is for this reason that its Kompanie were named after these Abteilungen instead of the ordinary 1st, 2nd, and 3rd designations.
In April 1944, these would be renamed to 1st, 2nd, and 3rd Kompanie. In April 1943, this unit had 35 vehicles. The last 10 vehicles arrived in May. The unit assembly and training was carried out until June 1943. By the time of the Kursk offensive s.Pz.Jg.Abt 655 was part of the Heeresgruppe mitte, but was not directly involved in combat. It would, however, be engaged with the Second Armee in trying to stop the Soviet attacks. This defense proved to be unsuccessful and the unit was forced to pull out in the direction of the Desna and Dnieper rivers. In a report dated 1st July, s.Pz.Jg.Abt 655 was noted to have lost eight vehicles: one to a mine, and the remaining seven during an air raid. All these were recovered and sent to Germany for repair. From November to the end of 1943, s.Pz.Jg.Abt 655 was mostly used in support of different Panzer Division, both in the attack and in the defense, around the Pripet Marshes.
The Nashorns proved to be effective, as can be seen in the report of Kompanie 521 during a combat operation defending Orel in mid July 1943, when following vehicles were claimed to have been destroyed: 1 x KV-2, 19 x KV-1s, 430 x T-34s, 1 x M3 Lee, 1 x T-60, 5 x T-70s, and 1 rocket launcher mounted on a tank chassis, with the loss of only two Nashorns. These numbers are just claims and were probably larger than reality.
s.Pz.Jg.Abt 655 received around 33 Nashorns as replacements (8 in July, 5 in October, November and December, and the last 10 in March 1944). This unit was even above the official combat strength with 47 operational (and 1 in repair) vehicles during June-July 1944.
In February, it was stationed in Belorussia in support of the elements of the Second Armee. By the end of May 1944, this unit was transferred to the 4th Panzer Armee, and it would see action in Ukraine on the Vistula river and at Lublin. In August 1944, s.Pz.Jg.Abt 655’s 1st and 2nd Kompanie were moved from Heeresgruppe Nord Ukraine to the training center at Mielau to be equipped with Jagdpanters and Jagdpanzer IVs.

Schwere Panzerjäger Kompanie 669

The 3rd Kompanie of s.Pz.Jg.Abt 655 was equipped with all remaining Nashorns (possibly around 24 vehicles). The unit was renamed to Einsatz Kompanie 655 and was stationed on the Eastern Front. It would remain on the Eastern Front supporting the 4th Panzer Armee near the Sandomierz bridgehead until late 1944. In November 1944, it was renamed to s.Pz.Jg.Kp 669. The combat strength of the s.Pz.Jg.Kp 669 was around 20 Nashorns (December 1944). During the Soviet offensive in January 1945, s.Pz.Jg.Kp 669 was part of 17th Panzer Division, suffering heavy losses during the battle for Kielce. In February 1945, it was reinforced with 13 new vehicles. The unit met its end during the battle for Prague in May 1945, when it surrendered to the Soviets.

Schwere Panzerjäger Abteilung 525

Schwere Panzerjäger Abteilung 525 was formed in August 1939 as Pz.Abw.Abt 525. During the attack on the West, this unit was equipped with 88 mm Flak 18 gun for use against tanks and bunkers. In France, it was used to attack parts of the Maginot line. Later, it would see action in the Balkans and in the Soviet Union. In late April 1943, it was ordered to reequip s.Pz.Jg.Kp 525 with Nashorns in a standard 45-vehicles organization. It was moved to Magdeburg where it was to be supplied with these vehicles, and by July 1943 the assembly of the 45 Nashorns was completed.
It was originally allocated to the 26th Panzer Division, but due to the need for crew training, the unit was only combat-ready by the beginning of August 1943. In preparation for the German occupation of Italy, s.Pz.Jg.Kp 525 was transported to northern Italy, but due to the Allied offensive, the unit was repositioned to the south. It was attached to different units (like the 90th Panzer Grenadier Division or 371 Infantry Division) and was mostly used for coastal defense. During December 1943, it was stationed near Rome as part of the 3rd Grenadier Division. From January 1944, it was engaged in defense of Cassino, where four Nashorns were destroyed and three damaged, but later repaired. Thanks to well selected and favorable combat positions, they managed to take advantage of their strong guns, even achieving a claimed kill from more than 2,800 m against an Allied Sherman tank. The 1st and 2nd Kompanie would see action during the Battle of Anzio in early 1944. In May, s.Pz.Jg.Kp 525 was again stationed around Cassino.
s.Pz.Jg.Kp 525 suffered losses during the Battle for Pontecorvo, where the Canadian Allied soldiers managed to capture one and destroy three vehicles. s.Pz.Jg.Kp 525 also saw action against Polish forces (part of the 2nd Corps) in August 1944, when one was captured and two destroyed.
On 31st August, s.Pz.Jg.Kp 525 was to be reinforced with Jagdpanthers and thus form a gemischte Jagdpanther-Abteilung. For this reason, the 1st Kompanie was sent to Mielau for rearming. The 1st Kompanie vehicles were given to the 2nd and 3rd Kompanies and these two would remain in Italy supporting the 10th Armee. In April 1945, what remained of the 2nd Kompanie was supporting the 26th Panzer Division and the 3rd Kompanie was supporting the 29th Grenadier Division. Many more vehicles were captured by the Allies during the German retreat across the River Po, as a number of Nashorns were abandoned by the Germans.
In late November 1944, the 1st Kompanie was in the process of reorganization, but due to the rapid development on the front, it was sent to reinforce Kapmfgruppe Fuehter-Begleit-Brigade. It was equipped with 10 Nashorns in late November 1944.

Schwere Heeres Panzerjäger Abteilung 93

The original name of this unit was Pz.Abw.Abt. 23 and it was formed in 1935. The name was changed to s.Pz.Jg.Abt 93 in October 1942. It was part of the 26th Panzer Division, stationed in France for training and rest. In June 1943, s.Pz.Jg.Abt 93 was chosen to be equipped with 45 Nashorns, and this process was completed in the period from July to September 1943. As the 26th Panzer Division was needed on the Italian front and s.Pz.Jg.Abt 93 was combat-ready, it was decided to detach it from this unit and attach it to the 7th Amree in Western France.
It was, from September 1943, engaged with Army Group “South” on the Eastern front for the support of the German retreat at the Dnieper River. and was used to support the German attack near Kryvyi Rog in late October. In early 1944, it supported the retreat of the 24th Division and the 6th Army. In early 1944, this part of the front was quiet, until 20th August when the Soviets launched a large offensive. Most elements of s.Pz.Jg.Abt 93 were lost together with the 6th Army near Chișinău (Kishinev). The 2nd Kompanie would survive and would be used to support s.Pz.Jg.Abt 525 in defense of the Rhine river. The final fate of what remained of s.Pz.Jg.Abt 93 is not clear.

Actions of the Schwere Panzerjäger Abteilung 93 and 525

s.Pz.Jg.Abt 93 and 525 were sent to the Western Front in order to reinforce the German forces which were desperately trying to stop the Allied advance to the Rhine. s.Pz.Jg.Abt 525 (1st Kompanie) was, in November 1944, equipped with 10 Nashorns while s.Pz.Abt 93 (2nd Kompanie) was, by December, equipped with just 12 Nashorns.
Both Abteilung 525 and 93 were attached to the 106th Panzer Brigade and operated in the Kolmar pocket until late December 1944 while suffering no losses. On 29th (or 27th depending on the sources) December, both were used to support Jagdpanthers from s.Pz.Jg.Abt 654. Later in January, they were used to reinforce the StuG.Brigade 280 until February. By that time, s.Pz.Jg.Abt 525 had suffered such heavy losses, that what was left was incorporated into s.Pz.Jg.Abt 93. In February, s.Pz.Jg.Abt 93 was renamed to s.Pz.Jg. Kompanie 93 due to its small size. By the end of February 1945, the Kompanie had only 10 vehicles left and was supporting 106th Armored Brigade near Cologne. In March, one Nashorn managed to destroy the new American T26E3 (at a distance of 500 m) tank near the town of Niehl. The Kompanie finally met its fate in April 1945, when it surrendered in the Ruhr area.

Schwere Panzerjäger Abteilung 519 and 664

Another unit to be equipped with Nashorns was s.Pz.Jg.Abt 519, which was formed in late August 1943. By November 1943, the last vehicle was received and the unit had 45 operational Nashorns. It was repositioned to the Eastern Front, where it supported the 3rd Panzer Armee. One of the first actions was the battle for Vitebsk, where the advancing Soviet forces were stopped. It would be stationed there from December 1943 to January 1944, during which time it helped repel many Soviet attacks. During the period from 10th December 1943 to 24th February 1944, s.Pz.Jg.Abt 519 claimed to have destroyed some 290 enemy tanks with the loss of only 6 vehicles, of which 4 were destroyed by their crews (due to a lack of towing vehicles).
From January to June, s.Pz.Jg.Abt 519 saw very few combat actions and was part of the 3rd Armee. From June 1944, s.Pz.Jg.Abt 519 was used to support the 4th Armee in Belorussia. By the end of June, s.Pz.Jg.Abt 519 claimed to have destroyed around 112 Soviet tanks with some losses. To replace the losses, this unit received 15 new vehicles (5 in March, April, and June). Due to the following fighting in July 1944, the unit lost many of its Nashorns. What was left of s.Pz.Jg.Abt 519 was used to support the Panzerkampfgruppe Hoppe by the middle of July. By August 1944, like the previous units, s.Pz.Jg.Abt 519 was also sent to Mielau to be equipped with Jagdpanthers, but was also equipped with StuG III.

Its remaining vehicles were given to s.Pz.Jg.Abt 664 which was equipped with towed 88 mm PaK 43 guns. This unit never achieved a full combat strength, with only around 12 vehicles being used (October 1944). It was engaged with HeeresGruppe Mitte, but was lost in late January 1945 on the Eastern Front.
Interesting to note is that Nashorn crews from s.Pz.Jg.Abt 519 had a habit of naming their (and paining it on the vehicle) vehicles after East German cities (like Pommern) or animals (Puma, Tiger, etc).

Schwere Panzerjäger Abteilung 88

s.Pz.Jg.Abt 88 was originally formed in late October 1940, and by late 1943 was mostly engaged on the Eastern Front. In late November, it was moved to Mielau to be equipped with Nashorns and for crew training. The unit reaches its full combat strength by January 1944 but was not ready for combat operation until February 1944.
By early 1944, s.Pz.Jg.Abt 88 was part of the 1st Panzer Armee on the Eastern Front. s.Pz.Jg.Abt 88 was heavily engaged during the battle of Kamienets-Podolsky. Later, in March/April 1944, this unit supported the 6th and 17th Panzer Divisions. An interesting fact is that, in May 1944, one s.Pz.Jg.Kp 88 Nashorn managed to destroy a new Soviet tank IS-2 in somewhat comic circumstances. This vehicle had actually been captured by the Germans and was in the process of being towed to the rear when it was spotted by the Nashorns. They immediately destroyed it without knowing it was actually captured by their comrades, although it is unlikely that the soldiers towing their prize back were amused by this incident.
This unit suffered heavy losses during the support of the Army Group A, around Brody and Lvov. In order to replace the losses, it received 30 new vehicles in August 1944. The rest of the year, this unit was stationed near Miechow. From January 1945, it was engaged against the Soviets near Lisow and Kielce.
In late January, an unknown number of Nashorns from this unit were supporting the German defense of Preiswitz near the village of Gieraltowice. During these actions, some Nashorns from s.Pz.Jg.Abt 88 were equipped with experimental night vision equipment, but in what numbers and how effective this system was is unknown. In March, the remnants of s.Pz.Jg.Abt 88 supported the 17th Armored Division near Lauban. s.Pz.Jg.Abt 88 would fight on until it surrendered in Prague in May 1945.

Schwere Panzerjäger Ersatz 43 and Asbuildung Abteilung

These two units were originally used for training and as reinforcements and were stationed at Spremberg. In desperation, both units were mobilized in the defense of the Oder River, where both would be lost. The number of vehicles that these units had is unknown.

The use of Nashorn in other units.

Panzerkompanie Kummersdorf was formed using the vehicle present at the Kummersdorf Weapons Testing Center, including at least one Nashorn. An unknown number of Nashorns were allocated to the 1st Panzer Division in December 1944. They were used to reinforce Pz.Jg.Abt 37, which had lost most of its Marder anti-tank vehicles. By April 1945, there was still an unknown number of Nashorns operational with this unit. It is possible that at least 12 Nashorns were given to the Das Reich Division in late December 1944, but precise information is not available.
By the end of 1944, there were still some 130-165 operational Nashorns in total (depending on the source). Most were located on the Eastern front, with smaller numbers to the West.

Schwere Panzerjäger Abteilung/Kompanie 424

The origin of this unit is not clear, and depending on the sources it is either marked as an Abteilung or a Kompanie. What is known is that s.Pz.Jg.Ab 424 was mostly destroyed in early 1945 near the Kielce area. The remaining elements of this unit (with only two Nashorns) were used to defend the Order river.

Combat effectiveness

The Nashorn, due to its powerful gun, could engage any Allied or Soviet tank at great ranges. The best tactics when employing Nashorns was to select a good and well-camouflaged combat position some distance behind the main front line and with a good field of visibility. From such positions, its gun could destroy enemy armored vehicles with less danger from retaliation fire. Of course, this was the best-case scenario, which could not always be implemented due to many factors like terrain or inadequate leadership.
As the Nashorns would be thrown into areas with expected heavy clashes, the local commanders would sometimes used them in a role or in a way for which these vehicles were not designed and suitable for. This inevitably led to unnecessary losses. In order to provide many German units with strong anti-tank firepower, the Nashorn units were sometimes divided into smaller groups which reduced their combat potential. This also caused logistical and communication problems which could not be easily solved. Another problem was the positioning of these vehicles too close to the front or the inadequate scouting of enemy forces.
To address potential misuse of the Nashorn, instruction sheets were given to the troops (at the battalion level) of the 3rd Armee. These sheets included instructions on how to properly use the new Nashorns. It indicated that s.Pz.Jg.Ab was to be used as mobile defense units against mass enemy armor. They should be used as Abteilung or Kompanie strength, and to avoid distribution in smaller groups. This could cause many potential communication, ammunition and maintenance problems. Due to its weak armor, the enemy should be engaged at ranges greater than 1 km, and the Nashorn should never be used as an assault weapon (like StuG III for example). The Nashorn should attack enemy vehicles from well-camouflaged positions. The local commander should receive advice from the Nashorn commanders on the proper use of the vehicle.
Good cooperation between Nashorn units and the units they were attached to wasn’t always possible. There were situations when Nashorn commanders refused to execute the orders given to them by local commanders. This was the case of the Kompanie 521 (part of s.Pz.Jg.Ab 655), which refused to attack a well-defended position (with 20 to 30 tanks) while advancing over 2 km of open ground. The proper use of the Nashorns was demonstrated by the Zug from Kompanie 521, when on 3rd July, 12 KV-1s and 4 T-34s were destroyed with the loss of only one Nashorn. The Nashorns were well positioned and camouflaged, which played a great part in this action.

Due to its weak armor, the Nashorn provided only limited protection and could be easily destroyed by enemy fire. Source: Pinterest

The Nashorn’s best defense was a well-selected combat position and good camouflage. This vehicle belongs to s.Pz.Jg.Ab 525 (February 1944). Source.
Scouting was also essential for the Nashorn units, as they lacked any proper vehicles to do the job. Usually, the Nashorn commanders would go on foot to the designated area of attack. What is interesting is that (depending on the combat situation), the commanders of the Nashorn vehicles would give orders to their crew from outside the vehicle during a combat operation. This was done so that the Nashorn commander could have a better understanding on the current combat situation, in this instance, a key importance was that the commander had to be in close proximity of his vehicle. As the Nashorns were used mostly as fire support from the distance this was possible to be achieved without any major problems.
Thanks to its deadly gun, the Nashorn could effectively destroy enemy tanks from ranges above 2 km. In one case, it was reported that a T-34 was destroyed from a range of 4.2 km! It is important to note that the Nashorn would rarely engage at ranges greater of 2 km for several reasons. While the gun was powerful enough, there was a problem with potentially wasting precious ammunition, as the hit probability was significantly lower at such distances. Ammunition production could not reach the demands and the general low ammo count that could be carried inside the vehicle compounded this issue. Another problem was that the sights would be slightly knocked out of alignment during driving, which would affect the precision of the gun, especially at longer ranges. There are other facts that also had to be taken into account like the wind, the quality of ammunition, and a bit of luck etc. Hitting enemy vehicles at ranges of over 3 km was an exception rather than a rule, and in most cases, crews avoided shooting at these ranges.
One of the best known Nashorn aces was Lieutenant Albert Ernst who served with s.Pz.Jag.Abt.519. During the fighting on 19th December 1943, he and his crew managed to destroy 8 Soviet T-34s. Later that month, they destroyed another 14 T-34s tanks with just 21 rounds of ammunition. By 7th February 1944, he was awarded the Knight’s Cross for destroying 25 enemy tanks and many anti-tank guns. In the summer of 1944, he was transferred to s.Pz.Jg.Abt 654.

Conclusion

With the creation of the independent Schwere Panzerjäger Abteilung equipped with Nashorns, the Germans had units that could provide support and increase the offensive capabilities of any units attached to them. This also created some issues, the most common of which was the misuse of these vehicles by the local commanders.
During its operational use, the Nashorn proved to be an effective anti-tank vehicle with an excellent gun, but it was not perfect. The main drawback (like all similar German open-topped tank destroyers) was the lack of armor. It was also a relatively large vehicle and thus difficult to camouflage properly and suffered from a low ammunition count, and a small traverse arc. Another significant issue was constituted by the great number of engine breakdowns due to overheating.

Surviving vehicles

Today, there are only three surviving Nashorn vehicles. One is located in the Kubinka Museum in Russia and another one is at the U.S. Army Center of Military History Storage Facility. The third vehicle is a part of a private collection in the Netherlands. It was a fully operational vehicle, but was badly damaged in a fire in 2019, and is currently under restoration.

WW2 German Tank Destroyers

Panzer IV/70 (V)

ww2 german tanks Nazi Germany (1944) Tank Destroyer – 930-950 built

During the Second World War, the Germans developed a large number of different Jagdpanzer designs. Some of these were hastily designed and made, some were temporary solutions, and there were also those which were specifically designed for the role of Jagdpanzer. The latter is the case with the late-war Panzer IV/70 (V). It was well protected, armed with a powerful gun and, with a low profile, it proved to be a deadly weapon. However, the effect of this vehicle on the battlefields of Europe in 1944 was limited, as production began late that year and very few reached the front lines.

First Jagdpanzer Designs

Even before the war, the famous German commander Heinz Guderian had predicted the need for highly mobile self-propelled anti-tank vehicles later known as Panzerjäger or Jagdpanzer (tank destroyer or hunter). The terms Jagdpanzer and Panzerjäger were, according to Germany military terminology and concepts, essentially one and the same. After the war, however, the Jagdpanzer term would be used to describe the fully enclosed tank destroyers while the Panzerjäger would be used for the open-topped tank destroyer vehicles.
In March of 1940, the first attempt to build such a vehicle was made. This was the 4.7 cm PaK (t) (Sfl) auf Pz.Kpfw. I, generally known today simply as the Panzerjäger I. It was more or less a simple improvisation, made by using a modified Panzer I Ausf.B tank hull and by mounting a 4.7 cm PaK (t) with a small shield on it. Later, during the attack on the Soviet Union and the battles in North Africa, the need for effective anti-tank vehicles became of greater importance for the Germans. The appearance of the towed 7.5 cm PaK 40 in increasing numbers somewhat solved this problem, but the main issue with this gun was its lack of mobility.
The need for a mobile anti-tank vehicle would lead to the development of the “Marder” series, which was based on several different tank chassis and armed with powerful and efficient anti-tank guns. Captured tanks and other vehicles would also be reused for this purpose. In 1944, the Nashorn, armed with the excellent 88 mm Pak 43, was put into production. But most of these vehicles were hastily designed and built and, while they did the job, they were far from perfect. These vehicles were built by using different tank chassis and installing a gun with a limited traverse in an open-topped superstructure. The two main issues were the great height, which made them extremely difficult to camouflage, and the general lack of an effective armor design.
The German infantry support self-propelled assault gun, the Sturmgeschütz, or simply StuG, (based on the Panzer III) proved to have great potential when used as Jagdpanzers. They had relatively good armor, a low profile, and could be armed with the longer barrelled 7.5 cm gun. The mass-produced StuG III Ausf.G armed with the longer 7.5 cm gun (L/48) was able to efficiently fight almost any Allied tank up to the end of the war. The StuG vehicles were also much easier to build than any German tank. In 1942, the first plans to equip the StuG with a stronger gun and armor were made. These would eventually lead to the development of the Panzer IV/70 (V) in late 1944.

Early Development of the Jagdpanzer IV

The story of the Panzer IV/70 (V) actually began in September 1942, when the Waffenamt issued a request for developing a new design of Sturmgeschütz – the Neuer Sturmgeschütze (or ‘Sturmgeschütze neue Art’ depending on the source) series. It was to be armed with the 7.5 cm KwK L/70 gun and protected with 100 mm frontal and 40 to 50 mm of side armor. It was intended to have the lowest possible height, a top speed of 25 km/h and a weight of up to 26-tonnes. According to original plans, a completely new chassis was to be developed but, due to the lack of industrial capacity, the Panzer IV tank chassis was chosen instead. During 1942, there were many tests of different designs for the new Jagdpanzer based on the StuG III design. At the same time, the firm of Alkett tested the installation of the StuG III superstructure on the Panzer IV tank chassis armed with the 7.5 cm L/70 gun (Gerät No.820). One was also fitted with a 10.5 cm gun and there was even a proposal to test the installation of an 88 mm gun. As this modification proved to be somewhat complicated and was not feasible for production in the near future, a new solution was needed. There were also proposals to combine some components from the Panzer III, IV, and the VK16.02 ‘Leopard’, but nothing came of this.
More extensive work on a new vehicle (based on the Panzer IV Ausf. H tank chassis) was carried out by the Vogtlandische Maschinenfabrik AG of Plauen (VOMAG) in early 1943, under the designation Gerät No.821. The wooden mockup was completed by May 1943 and the final prototype was ready by end of the same year. Adolf Hitler liked the new Jagdpanzer IV design and ordered that mass production should begin as soon as possible.
As already mentioned, the Jagdpanzer IV was based on the Panzer IV tank chassis with the turret and the top of the hull removed and replaced with a simple, easy to build, but highly-angled armored hull. The rear engine compartment was almost the same with minimal changes (the engine was also the same) but the original plans for the armament and armor had to be changed. There were inadequate numbers of the 7.5 cm L/70 guns available for the design, so the shorter L/48 had to be used instead. The maximum front armor was 60 mm instead of 100 mm but placed at a high angle which provided good protection.
In general, this vehicle had more or less the same operational combat characteristics as the already produced StuG III anti-tank version. Both had the same gun, but the Jagdpanzer IV had a more effective and much simpler armor design. While an effective tank destroyer, it could be considered a waste of time and resources as the StuG III did the same job and was already in production. Even the Inspector-General of the Panzertruppen, Heinz Guderian, was against the new Jagdpanzer IV vehicle from the start, due to it being so similar to the StuG III and as it was draining significant and necessary resources needed for the Panzer IV production.

The Jagdpanzer IV was armed with a 7.5 cm PaK 39 L/48 and protected with 60 mm frontal armor. Source
The Jagdpanzer IV would be produced from January to August of 1944 with some 769 to 784 vehicles built. The production was stopped in August as the new better armed and armored Panzer IV/70 (V) version was ready for production.

The Development History of the Panzer IV/70 (V)

In a conference held in late January 1944, Hitler himself urged for future development and rearmament of the Jagdpanzer IV with the more powerful 7.5 cm L/70 gun. Vomag was responsible for the implementation and realization of this task. One Jagdpanzer IV prototype (serial num. 320162) was rearmed with the 7.5 cm L/70 StuK 42 (SturmKanone) (also known as Pak 42 (PanzerabwehrKanone) gun) and had its frontal armor increased from 60 mm to 80 mm for testing in early 1944. These tests proved that the installation of the new gun in the Jagdpanzer IV was feasible and without major complications.
Photographs of this prototype were presented to Hitler in early April 1944, and the prototype vehicle was demonstrated to him on 20th April 1944 (his birthday). Hitler was excited about this vehicle and immediately ordered the beginning of mass production with some 800 Panzer IV/70 (V) vehicles per month. These numbers were never achieved, and the greatest monthly production reached just 185 vehicles.

This is the Panzer IV/70 (V) prototype (Fgst.Nr. 320162), it can be identified by its front rubber wheels, different gun mantlet design and by the added welded round armor plate over the left mounted machine gun port. The Panzer IV/70 (V) prototype at first did not have the gun travel lock but, due to the gun weight, it was later added. Source
At the same time, Alkett made attempts to increase the number of produced vehicles by making the whole superstructure design simpler and easier for production. This vehicle was known under the designation Panzer IV/70 (A), but only 278 would be built.
In July 1944, Hitler gave orders to terminate the Panzer IV production in favor of the Panzer IV/70 (V) and Panzer IV/70 (A) based on the fact that the Panzer IV was reaching its developmental peak and had few options available for improving its overall performance. The whole conversion process was to be completed by February 1945. As the German army was lacking sufficient numbers of operational tanks, this order was never fully implemented and the Panzer IV remained in production until the end of the war.

The Panzer IV/70 (V) was essentially the same vehicle as the Jagdpanzer IV but had thicker frontal armor and was armed with the longer gun. Source

Origin of the Panzer IV/70 (V) Name

By Hitler’s direct orders from 18th July 1944, this vehicle was officially designated as Panzer IV lang (V). The capital letter ‘V’ is for the vehicle’s manufacturer and designer, Vomag. In order to avoid any confusion with Panzer IV tanks and the previous L/48 tank hunter version, the German troops on the front referred to this vehicle as Panzer IV/70 (V) (the number 70 stood for the barrel length) and this designation was even officially adopted by the Heeres Waffenamt in November 1944. In some sources, this vehicle is also known as Jagdpanzer IV/70 (V). According to some sources, due to the vehicle’s slower speed and movement, the crews gave this vehicle the nickname “Guderian Ente” (Guderian’s Duck). It should be noted that, in German, ‘Ente’ not only means duck, but also urine bottle, which is also claimed to have been the reason the Panzer IV/70V received the name “Guderian Ente”.

Specification

Visually, the Panzer IV/70(V) was almost the same as the previous Jagdpanzer IV version, the most obvious difference being the length of the main gun and the added travel-lock. The Panzer IV/70(V) was built by using the Panzer IV tank chassis (some Ausf. H but mostly Ausf. J), which was, for the most part, unchanged.
The lower front hull was redesigned and had a more sharply angled shape. The transmission and the two steering brake inspection hatches remained, but the brake inspection hatches were square shaped and smaller than on the Panzer IV tank. During the Panzer IV/70 (V) production run the air intake vents on the brake inspection hatches were removed.
The suspension and running gear were the same as those of the original Panzer IV, with no changes to their construction. They consisted of eight small road wheels (on each side) suspended in four pairs by leaf-spring units. There were two front drive sprockets, two rear idlers and eight return rollers in total. The numbers of return rollers was reduced to three per side later in the production run and replaced with steel ones. As the vehicle proved to be nose-heavy, the front two road wheels were prone to being rapidly worn out or, in some cases, they even malfunctioned. To solve this problem, most vehicles were to be equipped with two (or more) steel-tired and internally sprung wheels, from September 1944 onwards. From February/March 1945, on some vehicles, the rear idler was replaced with a cast one which was easier to make. The ground clearance was increased to 40 cm. If needed, the normal tracks could be replaced with wider ‘East tracks’ (Ostketten).
The engine was the Maybach HL 120 TRM which produced 265 [email protected] rpm. The design of the engine compartment was unchanged. Maximum speed was 35 km/h (16 km/h cross country) with an operational range (with 470 l fuel) of 210 km. From September 1944 on, these vehicles were fitted with new flame dampening exhausts and mufflers (flammentoeter). The engine and the crew compartment were separated by a fire resistant and gas-tight armored firewall. In order to avoid any fire accidents, an automatic fire extinguisher system was installed in the engine compartment.
The Panzer IV/70 (V)’s new superstructure was well protected with its angled, thick and simple armor design. The angled shape of the superstructure provided thicker nominal armor and also increased the chance of deflecting enemy shots. This way, the need for more carefully machined armored plates (like on Panzer III or IV) was unnecessary. Also, by using larger one-piece metal plates, the structure avoided a lot of welding making it much stronger and also easier for production. The Panzer IV/70 (V) upper hull was built out of surface-hardened steel plates (Type E 22) manufactured by Witkowitzer Bergbau und Eisenhütten.
The Panzer IV/70 (V) upper front hull armor plate was 80 mm thick at a 45° angle, and the lower plate was 50 mm at a 55° angle. The side armor was 30 mm, the rear 20 mm and the bottom was 10 mm. The hull crew compartment had 20 mm of bottom armor. The upper superstructure frontal armor was 80 mm at a 50° angle (or 40° according to some sources), the sides were 40 mm at a 60° angle, the rear armor was 30 mm, and the top was 20 mm. The engine compartment design and armor was unchanged with 20 mm all around and 10 mm of top armor. Additional 5 mm thick armor plates were also provided for extra protection of the engine compartment sides.
The Panzer IV/70 (V) could be equipped with additional 5 mm thick armor plates (Schürzen) covering the side of the vehicle. In practice though, these would rarely last long and would simply fall off the vehicle during combat operations. Due to material shortages, by late 1944, stiff wire mesh panels (Thoma Schürzen) were used instead of the armor plates. These were much lighter and most sources claim that it provided the same level of protection as the solid type. It is often mentioned that Schürzen were designed as protection against shape-charged weapons but they were actually designed to counter Soviet anti-tank rifle projectiles. Moreover, Steven Zaloga points out in ‘Bazooka vs. Panzer’ that a unit from the American 1st Armored Group in the Sarrebourg area tested the Bazooka against one Panzer IV equipped with stiff wire mesh panels similar to the Thoma Schürzen. The tests showed that the wire mesh panels did not offer any protection against shape-charged weapons.
One more line of protection was the possible application of Zimmerit anti-magnetic paste to counter magnetic anti-tank mines, but the use of this paste would be abandoned in the late stages of the war.

The Schürzen side plates, added for extra protection, can be observed in this photo, as well as the vehicle’s small size. The gun lock, in this case made out of solid metal, is also noticeable. Source
The Panzer IV/70 (V) tank destroyer’s main armament was the 7.5 cm StuK 42 L/70 cannon, also known as the 7.5 cm PaK 42 L/70. This gun was more or less the same one used on the German Panther tank. The elevation of the 7.5 cm StuK 42 L/70 was from –5° to +15° and the traverse was 20°. The main gun was not placed at the vehicle’s centre, but was instead moved some 20 cm to the right side. One 80 mm thick cast gun mantlet acted as extra protection for the gun. The main weapon was produced by Gustloff-Werke (Weimar) and Škoda (Pilsen). A hydro-pneumatic equilibrator was provided for better gun balance and one iron counter-weight was added at the end of the recoil guard. To avoid damaging the main gun when on the move, a heavy travel-lock was provided. In order to free the gun, the gun operator had only to elevate the gun a bit and the travel lock would fall down. This allowed for a quick combat response but also avoided the need for a crew member to exit the vehicle in order to do it manually.
The main gun was not equipped with a muzzle brake. The first Jagdpanzer IV produced were equipped with muzzle brakes but, during combat action, the crews often removed them due to the dust clouds created during firing. This reduced the visibility but more importantly gave away the vehicle’s position to the enemy. From May 1944 on, the muzzle brake was removed from production and this would be also carried on with the later Panzer IV/70 (V). As this gun required a large amount of room and the use of large one-piece ammunition, the Panzer IV/70 (V) interior was very cramped and the ammunition capacity was only 55 rounds (or 60 depending on the source). Around 34 were armor-piercing (AP) (PzGr 39/42 or 40/42), while the remaining 21 were high-explosive (HE) (SpGr 42). The ammunition was stored along both wall sides and held in ammunitions racks.
The secondary weapon used was the MG 42 machine gun with some 1,200 rounds of ammunition. Unlike most other German vehicles, a ball mount was not used on this vehicle. The machine gun port was instead protected with a movable hemispherical-shaped armored cover. The machine gun mount was located to the vehicle’s right side. The Panzer IV/70 (V) was also equipped with the Nahverteidigungswaffe (close defense weapon) with some 40 or more rounds of ammunition, located on the vehicle top and covered with a round armored cover.
Unknown numbers of late built vehicles were equipped with the ‘Vorsatz P’ curved muzzle attachment for the MP 43/44 (7.92 mm) assault rifles. The mounting for this weapon was placed on the loader’s hatch door and was operated by him. The last line of defense was the crew’s personal weapons.

The four-man crew consisted of the commander, gunner, loader/radio operator, and the driver. The driver’s position was on the vehicle left front side but his view of the surrounding area was limited as he only had a front mounted periscope and a small periscope pointing to the right to see out of. Behind him was the gunner’s position, which was provided with an Sfl.ZF 1a gun sight for acquiring targets. This sight was linked to an Azimuth indicator, the purpose of which was to tell the gunner the precise and current position of the gun. When in use, the sight was projected through the sliding armored cover on the vehicle’s top armor. For operating the gun, there were two traverse hand wheels. The lower wheel was for the traverse and the upper one for the elevation. The gunner was also provided with a recoil shield, while the loader was not.
Behind these two was the commander’s position, which had a rotating periscope located in the escape hatch and one pointing to the left. The commander had a small additional hatch door for the use of a retractable Sfl.4Z telescope. The commander was also responsible for providing the loader with the ammunition located on the left side wall.
The last crew member was the loader, who was positioned on the vehicle’s right side. He operated the radio (Fu 5 radio set) which was located to the right rear and he also doubled as the MG 42 machine gun operator. There was a small opening located above the machine gun which provided the gun operator with a limited view of the front. When not in use, the machine gun could be pulled into a small travel lock which was connected to the vehicle’s roof. In that case, the machine gun port could be closed by pivoting the hemispherical-shaped armor cover. The use of this machine gun type is strange, as the usual hull mounted machine gun in all German armored vehicles was the MG 34. Nearly all periscopes were protected with an armored flap cover.
The crew could enter the vehicle through two hatches located at the top of the vehicle. There was an additional floor escape hatch door that could be used in case of emergency.
In the hope of removing any extra weight at the front, most spare parts and ancillary equipment were moved to the rear engine compartment. These included things such as spare tracks, wheels, repair tools, the fire extinguisher and crew extra equipment. Some vehicles had an armored and welded base for a 2-tonne crane added on the superstructure roof. The rear tow bars were changed with vertically positioned ones.
The dimensions were: length 8.5 m, width 3.2 m, and height 2 m (or length 8.58 m, width 3.17 m, and height 1.85 m according to other sources). Total combat weight was around 25.8 metric tons.

Panzer IV/70 (V) Befehlswagen

An unknown number of Panzer IV/70 (V) were modified to be used as Befehlswagen (command vehicles). These vehicles had additional radio equipment installed, the FuG 8 30 radio station (30 W power) with an operational range of 80 km. The extra equipment was positioned behind the loader and was to be operated by an extra crew member (but some sources do not mention the fifth crew member). The Befehlswagen would also use a Sternantenne (star radio antenna) which was 1.4 m long and located on the left side of the engine compartment.

Production

Production was carried out by Vomag and, from November 1944 through April 1945, some 930 vehicles were built. Maximum production was achieved in January 1945, with 185 completed vehicles that month. Due to the bad situation in Germany, the production dropped rapidly in February to 135 vehicles, and dropped further to only 50 vehicles produced in March. The last 10 vehicles were to be completed in April, but it is possible that this was never achieved.
Like many other German military vehicles, authors cannot agree on precise production numbers. Most quote the figure of 930, while some, like Hilary Louis Doyle, quote 950 produced vehicles. According to Duško Nešić, some 940 were built, whereas Krzysztof M. and George P. estimate that between 930 to 940 vehicles were produced.

Organization

The Panzer IV/70 (V) would be used to equip many different German units. For Panzer and Panzer Grenadier Divisions, they were grouped into Panzerjäger Abteilungs. The Panzerjäger Abteilung usually had two Panzerjäger Companies. These Panzerjäger Companies were to be equipped with 10 to 14 Panzer IV/70 divided into three Platoons, with one to three vehicles assigned to the Company HQ. As the Panzer IV/70 did not reach the front in great numbers, these units were often below the officially prescribed combat strength.
The Panzer IV/70 (V) was also used to equip Kampfgruppen (Combat/battle groups). As ordered by Adolf Hitler (on July 2nd, 1944), small armored Kampfgruppe were to be formed. These would later be renamed to Panzer Brigaden. These groups were to be equipped with 30 to 40 tanks and self-propelled guns. As the Panzer IV/70 began to become available in sufficient numbers, it was also included in these units.

Although these vehicles were designed as tank destroyers with thick armor, their best defense was a well-selected and camouflaged position. Source

Jagdpanzer tactics

The term Jagdpanzer could be somewhat misleading. Despite the good frontal protection and the strong gun (in the case of this vehicle), its job was not to go on offensive hunts, either in the open or in urban areas, for enemy tanks. The Jagdpanzers were more of a defensive weapon concept, and their primary mission was to engage (if possible in great numbers) enemy tanks and to act as fire support at long ranges from carefully selected and well-camouflaged combat positions, usually on the flanks.
In offensive operations, they would support Panzer units from a safe distance and on the flanks. If the attack was successful, they were to move to new combat positions. In case of a failed attack or even in false retreat, they were to form a firing line in order to trap and destroy any enemy advancing armor units.

This vehicle, belonging to the 1st Panzerjäger Abteilung (1st Panzer Division), was pictured on the Western front in late 1944. Source
In support of the infantry, once the objective was captured, they were to remain there until that location was secure from any imminent enemy counterattack. After this was achieved, they were to return to the rear and wait for future orders. In the case of enemy attacks, they were to provide long-range support fire against enemy heavy armor. In retreats, the Jagdpanzers would be used to form defensive positions in the new rear lines.
Engagement with enemy tanks at close range (especially from the sides) was very dangerous for such vehicles, as they lacked a fully traversing turret, meaning they could not quickly respond to enemy movements. For example, in urban (especially in destroyed cities) areas, the lack of a fully traversing turret could prevent them from engaging enemy armor that got too close, as these hostile tanks had a clear advantage with their turret. Despite the Panzer IV/70 (V)’s excellent frontal armor, the sides and rear were weak. The greatest defense was a well-selected combat position, which any good Jagdpanzer commander had to learn to take advantage of.

In combat

The first units to be equipped with the new Panzer IV/70 (V) were the 105th and 106th Panzer Brigades in early August 1944. These two units were engaged against Allied forces on the Western Front. These were followed (also in August) by the 11.Abt. Panzer Regiment “Großdeutschland” Führer Begleit Brigade, 107th Panzer Brigade, Führer Grenadier Brigade, 109th Panzer Brigade. 110th Panzer Brigade, each equipped with 11 Panzer/70 (V) vehicles.
Despite the production of nearly 1000 vehicles, the distribution process to the front line units was too slow. This was mostly due to the increased number of Allied bombing and ground attack actions in Germany, which caused huge problems for transporting these vehicles (and any other) to the front. The Panzer IV/70 (V) began to reach front line units in great numbers only from January 1945 on, and by that time, it was too late. The largest concentration of Panzer IV/70 (V) (137 vehicles) for one combat action was during the last German offensive operation on the Western front, during the fighting in the Ardennes in December of 1944.
While the Panzer IV/70 (V) was a tank destroyer, it was also sometimes used in other roles, such as an assault gun. When acting in this role without infantry support, it proved to be an easy target for enemy anti-tank (bazooka armed) teams, as shown during an attack on the Krinkelt-Rocherath villages. The Panzer IV/70 (V) from the 12th SS Panzerjäger Abteilung (12th SS Panzer Division “Hitlerjugend”) were used to attack elements from the American 2nd Infantry Division which was defending the Krinkelt-Rocherath villages and the Lausdell crossroads. The first attacks on the American position at Lausdell crossroads were made with the support of two Panzer IV/70 (V) companies on 17th December 1944. The Americans had no armor available at this point, but had artillery support and placed large numbers of anti-tank mines. During the attack on the Lausdell crossroads, several Panzer IV/70 (V) (from the 2nd Company) were leading the attack supported by small Panzergrenadier infantry groups, which were hiding on the Panzer IV/70 (V) engine decks. Once the German vehicles were spotted, they were immediately bombarded by the American artillery. One vehicle was destroyed by an artillery hit, and two were immobilized by mines. One immobilized vehicle was firing at the American positions, but was eventually destroyed with a combination of thermite grenades and a fuel canister. Two more Panzer IV/70 (V) were destroyed by bazooka teams. After regrouping, the Germans repeated the attack later that day but it was met with heavy artillery fire and between four to seven armored vehicles (of an unknown type) were reported destroyed. One last attack attempt was made at 22.30 hrs, but with the support of artillery, this attack was also repulsed.
The following day, the Germans attacked the Krinkelt-Rocherath villages with elements from the 12th SS Panzerjäger Abteilung 2nd company with the support of SS Panzergrenadier 25th Regiment. The American positions guarding the first line defense trenches were overrun. The Panzer IV/70 (V) that entered the village managed to destroy three M4 tanks. There was heavy fighting that lasted the whole day, but the Germans withdrew the next morning expecting reinforcements and supplies. The next day they continued with the attacks, but, in the end, they could not breach this line and suffered heavy losses (one Panzer IV/70 (V) was lost together with several Panzer IV and Panther tanks). The 12th SS Panzerjäger Abteilung, at the start of the Ardennes offensive, had 22 Panzer IV/70 (V) but had lost three vehicles with seven damaged, although they were subsequently recovered and repaired.

The Americans used a captured Panzer IV/70 (V) during the winter of 1944/45 to test the effectiveness of bazookas. While the front armor proved impervious, the sides and the rear were vulnerable to this weapon.
The Panzer IV/70 (V) also saw some heavy action on the Eastern Front, where it also proved to be an effective tank destroyer, as in the case of schwere Panzerjäger Abteilung 563. The schwere Panzerjäger Abteilung 563 received 18 Jagdpanthers and 22 Panzer IV/70 (V) divided into two companies on 20th January 1945. The next day, this unit was sent to Allenstain in Poland. The 563rd participated in heavy fighting in Poland, where it claimed to have destroyed some 58 enemy tanks with the loss of four Panzer IV/70 (V) and one Jagdpanther during a period of 10 days. By the beginning of February 1945, this unit was a mere shadow of its former strength with only 5 Jagdpanthers and 3 Panzer IV/70 (V) left. All remaining vehicles had to be abandoned or destroyed by their crews due to a lack of fuel, spare parts and the muddy terrain.
Over thirty different German units were equipped, usually with about 11 such vehicles each. These would be used to support many German front line Divisions, including 2nd SS Panzer Division, 1st SS Panzer Division, 7th, 8th, 13th, and 21st Panzer Divisions, 20th Panzergrenadier Division, Panzer Abteilung “Jüteborg”, 510th Heeres Panzerjäger Abteilung and others.
Some StuG-equipped units (Sturmgeschütz-Abteilung) were reinforced with IV/70 (V) vehicles, like the 226th and 210th Sturmgeschütz-Abteilung. There was also a last-ditch attempt to form a mixed company equipped with Panzer IV/70 (V) and (A) prototypes at Kümmersdorf on 15th February 1945. One of the last units to receive 10 new built Panzer IV/70 (V) was the 33rd Panzer Regiment from the 9th Panzer Division on 17th April 1945.
By early April 1945, the German Army had around 285 operational Panzer IV/70 (V). Nearly all were stationed on the Eastern Front (274), while only small numbers were stationed on the Western Front (8) and only three in Italy.
By late 1944, there was a general lack of Panzers, so the Germans were forced to use the Jagdpanzers as replacement vehicles instead. The Panzer IV/70 (V) suffered losses as it was often used in the role of Panzer, a role for which it was not suited nor designed for. But as there were no other solutions, something was better than nothing.

Other IV/70 (V) operators

The Bulgarians, after changing sides in September of 1944, immediately began attacking their former German ally. In March 1945, their armored force was supplemented with one captured Panzer IV/70 (V) (Ser. Num. 320662) supplied by the Soviets. In Bulgarian service, this vehicle was known under the Maybach T-IV name. This vehicle still exists to this day and can be seen at the National Museum of Military History in Sofia.
Unknown numbers of captured Panzer IV/70 (V) were supplied to the Romanian army by the Soviet Union (possibly after the war). In Romanian service, they were known under the TA T-4 designation and remained in service until 1950, when they were replaced with more modern Soviet equipment. TA was an abbreviation for ‘Tun de Asalt,’ (Assault Gun) and T-4 was the Romanian designation for the Panzer IV.
After the war, Syria received a number of older German captured armored vehicles including unknown numbers of Panzer IV/70 (V) and Jagdpanzer IV. These were supplied by the Soviets and they saw action during the Six Day War.

Surviving vehicles

A small number of Panzer IV/70 (V) survive to this day and can be seen in several museums around the world. One can be found in the capital city of Bulgaria, Sofia, one in Shrivenham in the UK, two in the USA (Patton Museum and Aberdeen Proving Grounds), one in Canada (Ottawa), and one at Kubinka (Russia).

Conclusion

Despite the issue with its weight, the Panzer IV/70 (V) proved to be a dangerous and effective anti-tank weapon as it could destroy all Allied armored vehicles from great ranges. It had a very low profile which made camouflaging it a very easy task. The strong frontal 80 mm angled armor provided efficient protection from enemy fire, especially from a distance.
But, on the other hand, it was built too late and in insufficient numbers to have any large impact on the War. The late introduction and long development time of this vehicle also disrupted the production of the much needed Panzer IV tank, which the Panzer IV/70(V) was sometimes forced to replace in combat, being used as a tank despite being unsuitable for the purpose.

WW2 German Tank Destroyers

Panzerjäger 38(t) für 7.62 cm PaK 36(r) (Sd.Kfz. 139) Marder III

Nazi Germany (1942-43)
Tank Destroyer – 344 Built

As the German armored forces advanced on all fronts in 1940 and 1941, they encountered many different enemy tank types that were almost immune to guns of their Panzers. In France it was the B1 bis and the British Matilda (when the Germans met the first Matildas at Arras, it was a very unpleasant shock), in the Soviet Union were the famous the T-34 and the heavy KV-series, and in Africa again (in larger numbers) the Matilda tank. While they were able to defeat these by various means, the Germans were pressed to find a better way to combat these threats. The newly developed towed anti-tank guns (like the PaK 40 built in 1942) could efficiently destroy these tanks, but they were not suitable for offensive operations. A logical solution was to try to mount these towed anti-tank guns on a tank chassis and thus solve problem of mobility, and so the new Panzerjäger’s were born.
These new vehicles followed the same pattern: most were open-topped, with limited traverse, and thin armor. They were, though, armed with an effective anti-tank gun, and usually with one machine gun. They were also cheap and easy to build. Panzerjäger’s were, in essence, improvised and temporary solutions, but effective ones nevertheless. Just as the name suggests (tank hunter), they were designed to hunt down enemy tanks at long range on open fields. Their primary mission was to engage enemy tanks and to act as fire support at long range from carefully selected combat positions, usually on the flanks. This mentality led to a series of such vehicles named ‘Marder’ that was developed using many different armored vehicles as a base.

A canvas cover was often installed over the fighting compartment and used to protect the crew from bad weather. It offered no real protection during combat. Source:www.worldwarphotos.info

Panzer 38 (t)

The TNH – LT vz.38 tank was developed and built by the Czech ČKD company (Českomoravska Kolben Danek) in the second half of the nineteen-thirties. Production of the vz. 38 began in late 1938 but, by the time of the German annexation of Czech territory, not a single tank was handed over to the Czech army. Germany captured many brand new vz.38 tanks and, in May 1939, a delegation was sent to the ČKD factory to examine their operational potential. The Germans were so impressed with this tank that they were quickly introduced into Wehrmacht service under the name Pz.Kpfw.38(t) or simply Panzer 38(t). The ČKD factory was completely taken over for the needs of the German army under the new name BMM (Bohmisch-Mahrische Maschinenfabrik).
The Panzer 38(t) was built in relatively large numbers, saw combat action from Poland to the end of the war and was considered an effective tank for its class. But, from late 1941 on, it became obvious that it was becoming obsolete as a first line combat tank. The Panzer 38(t) chassis, on the other hand, was mechanically reliable and was highly suitable for use for other purposes, a fact which the German exploited to the maximum. Many different armored vehicles were built using the Panzer 38(t) chassis including many Panzerjager versions, like the Marder III armed with a modified Russian 7.62 cm field gun (M1936).

Heavy camouflage and a well selected combat position was necessary for the crew’s survival. Source:www.worldwarphotos.info

Panzerjäger 38(t) für 7.62 cm PaK 36(r) (Sd.Kfz. 139) ‘Marder III’

The need for such a vehicle became obvious during the first year of Operation Barbarossa (the German invasion on the Soviet Union), when German ground forces encountered the T-34 and the KV tanks. Fortunately for the Germans, they captured large numbers of the 7.62 cm field gun (M1936) which had good anti-tank firepower. This gun was immediately put to use by the German ground forces, but mobility was an issue, so an idea appeared to install this gun on tank chassis in order to increase its mobility.
The Panzer 38(t) armed with this Soviet gun was named 7.62 cm PaK36 (r) Pz.Kpfw.38(t) ‘Marder III’ Sd.Kfz.139 or Panzerjager 38(t) fur 7.62 cm PaK 36(r) Sd.Kfz.139 ‘Marder III’ depending on the source.

Construction

The Panzer 38(t) chassis and the running gear were almost unchanged. The suspension was also the same as the original, consisting of four large road wheels (connected in pairs to a central horizontal spring). There were two front drive sprockets, two rear idlers, and four return rollers in total (two on each side).
The design of the engine compartment was also unchanged. The first series of Marder III built were based on the Ausf.G tank chassis and were equipped with the Praga EPA (125 hp) six cylinder engine, but later models (built using the Ausf.H tank chassis) had a stronger Praga AC (150 hp) six cylinder engine. Both engines were connected to a transmission that had five forward and one reverse gears. Two starters were installed, one was electric and the second was an inertial starter located in the rear of the vehicle. Top speed was around 42 to 47 km/h and some 20 km/h on cross country. Two double skin fuel tanks with some 200 l in total were mounted on both engine sides. The operational range was around 185 km on good roads.
The tank hull was somewhat different from the original one used on the Panzer 38(t). In order to install the new weapon mount, it was necessary to remove the turret, the top part of the hull armor and the ammo storage for the old gun. The front and side hull armor with the three observation hatches (two on front and one on the right side) and the hull machine gun were unchanged. The front hull armor was 50 mm thick, while the sides and rear were 15 mm thick.
On top of the hull, the new armored (open from top and rear) superstructure with the main gun was installed. On the upper part of the hull, about where the turret ring was, a ‘T’ shape gun mount was bolted in. The main gun and the gun crew were protected with an enlarged armored shield which consisted of six armored plates bolted together over the original gun shield. This armored shield offered the gun crew some protection from the front and sides, while the top and the rear were open. The thickness of the new modified gun shield was around 14.5 mm plus the armor from the original gun shield, and 10 mm on the sides.
The rest of this vehicle was covered in armored plates with different shapes and different angles, on top and over the tank hull (some 15 mm thick). The engine compartment was also protected from the sides with two armored plates.
Due to being an open-topped vehicle with low thickness armor and high silhouette, crew protection was on a very low level. Camouflage and a well-selected field position were essential for survival. As an open topped vehicle, the crew was also exposed to weather conditions. A canvas cover could be placed over the vehicle but it limited the crew’s view of the surroundings.
The main gun, as previously noted was the 7.62 cm PaK 36(r), with some 30 rounds of ammunition. Most rounds were placed below the gun mount, with three rounds mounted on the left and right side below the gun shield. In practice, crews would store many more rounds in any available free space inside or outside the vehicle. Due to the gun weight, installation of a heavy travel lock was necessary, in order to avoid damaging the main gun when on the move. At first, a simple steel tube shape travel lock was used, but during the war it was replaced with a strengthened triangle shaped one filled with sheet steel.
The elevation of the Pak 36 was -7° to +16° with a traverse of 50°. The maximum rate of fire was 10-12 rounds per minute. Armor penetration with the standard AP round from the range of 1000 m (at 0° angled armor) was around 108 mm. By using the much better (but rare) tungsten round (7.62 cm Pzar. Patr. 40), the armor penetration increased up to 130 mm at the same range.
The secondary weapon was the original Czech 7.92 mm ZB-53 (named MG-37(t) in German use) with some 1,200 rounds of ammunition. The crew would also carry their personal weapons for self defense.
The Marder III crew consisted of the commander/gunner, loader, driver and radio operator. The driver and the radio operator were positioned inside the vehicle, the same as on the Panzer 38(t). Two (modified) front hatch doors were located at the front top of the new armored superstructure, just beneath the main gun. These doors were used by the driver and the radio operator to enter or exit their positions. The driver was located on the right side and had two observation hatches (in front and on the right side). The radio operator (and also the hull ball mounted machine gun operator) was located to the left with his radio instruments (Fu 5 SE 10 U). The commander/gunner and the loader were located behind the new gun shield in the upper part of the vehicle. On the left side was the gun operator and the loader was on the right side. They only had a limited amount of space behind the gun shield. Used rounds and other equipment, spare parts or supplies were usually carried in the rear mesh wire basket.
Total weight was some 10.67 t. The length was 5.85 m, width 2.16 m and the height was 2.5 m.

Organization of the self-propelled anti-tank battalions

Special self-propelled anti-tank battalions (Panzerjäger-Abteilungen Sfl.) were formed and equipped with the new Marder III. Both the Wehrmacht and the Waffen SS fielded such battalions. Later during the war, as more and better self-propelled anti-tank were built, the surviving Marder IIIs were given to infantry (motorized) divisions or returned to Germany to be used as training vehicles.
Self-propelled anti-tank battalions were supposed to be equipped with 45 Marder III vehicles. Three were used as command vehicles (Stabskompanies) and 12 vehicles were positioned in each of the three Panzerjäger-Kompanien. The Panzerjäger-Kompanien were divided into three platoons, each with four vehicles. The rest were used to equipped HQ section (Gruppe Fuhrer) with two vehicles in each Kompanie.
These anti-tank battalions were equipped with other vehicles necessary for their successful operation: over 20 motorcycles (half were with sidecars), 45 cars, more than 60 trucks, some 13 half-track of different types (four Sd.Kfz.10, six Sd.Kfz.7 and three Sd.Kfz.8) and one Sd.Kfz.251. Sometimes, modified ammunition Panzers were used, but this was rare. In total, Self-propelled anti-tank battalions had around 650 men.
It is important to note that this information and the numbers presented were, in the best case, purely theoretical, for several reasons: because of the losses during the war, not many Marders were produced to equip all units. Also, there were insufficient men and materials, many vehicles were often on repairs etc.

In combat

The majority of the Marder III tank hunters were sent to the Eastern Front, where such a vehicle was desperately needed by the German forces. Almost a third of the produced Marder IIIs would be sent to North Africa, helping the DAK (Deutsches Afrikakorps) fighting against British and later even American tanks.

In North Africa

After the failed Italian attack on the British positions in Egypt, Mussolini was desperate to convince Hitler to send military aid to his shattered forces in Africa. Initially, Hitler was not interested in the Mediterranean. He reluctantly decided to help his ally and sent an armored force under the leadership of Erwin Rommel.
The Germans quickly found out that, beside the famous ‘88’ (88 mm Flak gun), the standard 3.7 cm and short 5 cm anti-tank weapons struggled against the well armored British Matilda tank. A number of captured and modified 7.62 mm PaK 36(r) guns were also sent to the North African front. One great issue with this weapons was the low mobility on a front were speed was essential for success. Several solutions to this problem were tested, like the Sd.Kfz..6 armed with the 7.62 mm PaK 36(r) in a box shape casemate and the experimental half-tracks armed with the 7.5 cm L/41 gun.
Before sending the new Marder to Africa, it was necessary to adapt them for service in the African desert. In March 1942, one Marder III was equipped and tested with sand filters. The tests were successful and later vehicles sent to Africa would have these filters. The number of vehicles sent ranges from 66 to 117 (depending on the sources).
The first Marder IIIs (6 vehicles) arrived to North Africa in May 1942, with the last one arriving in November 1942. The freshly arrived Marder IIIs were used to reinforce and equip anti-tank battalions of the 15th and 21th Panzer Divisions.
By late October 1942, the 15th Panzer Division had at its disposal some 16 Marder III vehicles. All were allocated to the 33rd Anti-Tank Battalion, together with a number of towed 5 cm PaK 38 anti-tank guns. After the British attack at El Alamein at the end of October 1942, the 33rd Anti-Tank Battalion was under a heavy attack. It managed to inflict some heavy damage to the British advance units but it also suffered losses. Almost all the Marder IIIs were lost, except one.
In September 1942, the 39th Anti-Tank Battalion of the 21st Panzer Division had around 17 PaK 38 guns and 18 Marder IIIs divided between two Kompanien (1st and the 2nd). There is little information on this unit’s participation in the Battle for Alam Halfa (October-September 1942). In late October 1942, during the British counterattack at El Alamein, all 18 Marder III vehicles were reported to be still operational. By the 25th of October, this unit was pulled out into reserve. The next day, the 2nd Kompanie was sent to the north to help stop a British attack while the 1st Kompanie was located to the south.
By the end of October, the 39th Anti-Tank Battalion was heavily involved in fighting, trying to free some encircled units of the 164th Light Division. On the 4th of November, the surviving German forces were forced to retreat. The 39th Anti-Tank Battalion lost all its Marder IIIs and had only a few 5 cm PaK’s left. By December, the 21st Panzer Division had only two Marders III, which were not even fit for action.
In March 1943, after some resting time, the 39th Anti-Tank Battalion was reformed and reinforced. The 1st Kompanie received 9 Marder IIIs and the 2nd Kompanie received Marder III Ausf.H (version armed with the 7.5 cm PaK 40). They fought in Tunisia until the Axis surrender in May.
The 10th Panzer Division was pulled out from the Eastern Front and after some time resting was reinforced with 9 Marders III in July 1942 (90th Anti-Tank Battalion). The 10th Panzer Division was sent to the North African front in November 1942. In Africa, this unit was engaged in many battles against the British and newly-arrived American forces and the losses were heavy. The last Marder III was reported lost in March 1943.
The 190th Anti-Tank Battalion and the 605th Anti-Tank Battalion were supposed to be equipped with Marder IIIs, but there is little evidence that this ever happened.
The British tank crews learned to fear the Marder’s firepower at long ranges. When the British first learned about this new German tank hunter they assumed that was armed with the famous ‘88’ gun.

In Russia

The 1st Panzer division was heavily engaged in Russia during the first year of German invasion. In May 1942, it was reinforced with six Marder IIIs which were used to equip the 37th anti-tank battalion. This unit’s first action was during the German attack (July 1942) on the Soviet positions around Belyj and Szytschewka south of city Rzhev (some 230 km west from Moscow). By September 1942, this unit was credited with destroying some 99 Soviet tanks. By the end of November and beginning of December, it was engaged in defensive operations in the region of southwest of Bjeloj (Tver Oblast near Moscow). Due to the long and difficult fighting, this unit was exhausted, so it was sent to France (end of December) for rest and relaxation. The surviving Marders were left behind, but there is no information about which units received them.
The next unit to receive the Marder III was the 38th anti-tank battalion of the 2nd Panzer Division. In May 1942, the 38th anti-tank battalion was reinforced with 9 Marder IIIs, one Panzer II Ausf.B Befehlspanzer and a few Panzer I Ausf.B modified into ammunition tanks. This unit was not immediately sent to the front, but instead spent the next few months in training. It was ready for active duty in July 1942, and was immediately involved in heavy fighting around Bjeloj. As it was the only unit to have enough firepower to destroy Soviet heavy tanks at long ranges (the first new Panzer IVs with the longer guns would arrive in this division in August 1942), it managed to claim 14 Soviet T-34 tanks with no losses. On the 11th August, the 2nd Panzer Division managed to destroy 20 enemy tanks, but most were destroyed by the Marders. In December 1942, the 38th anti-tank battalion received a few Marder III Ausf.H (7.5 cm PaK 40). From August 1942 to March 1943, the 38th anti-tank battalion was heavily engaged in many combat operations on the Eastern front. Few were lost due to enemy fire, but many were lost due mechanical breakdowns. From March to April 1943, this unit was sent to the rear for rest. In March, it was again reinforced with 9 new Marder III Ausf.H. This unit did not see action again until July 1943. Due the standardization of weapons within anti-tank battalions in late 1943, the 38th anti-tank battalion was forced to give up all its remaining Marder IIIs to the 616th anti-tank battalion by the end of June 1943.
The SS units were also given a number of Marder III vehicles as they were seen as elite fighting forces and deserved only the best available equipment. The 2nd SS Anti-Tank Battalion of the SS ‘Das Reich’ Panzer division received 9 Marder IIIs in May or June 1942. The first combat action of this unit was in February 1943 on the Eastern Front near Khrakov (in Ukraine). At first, not many vehicles were operational due to the low temperature which caused problems with frozen condensed water gathering at the bottom of the two fuel tanks. In late February, the 2nd SS Anti-Tank Battalion was reinforced with (unknown number) the Panzer II based Marder IIs. During the Operation Zitadelle, the 2nd SS Anti-Tank Battalion saw some heavy action. By the end of summer 1943, the 2nd SS anti-tank battalion was so depleted that this unit was disbanded, and the soldiers who survived were sent as replacement to other SS Stu.G. Abt. DR (units equipped with StuG vehicles). An interesting fact about the 2nd SS Anti-Tank Battalion is that captured and reused several T-34 tanks without the turret as ammunition tanks.
The Marder III fought until the end of the war and, on the 22nd of January 1945, a dozen or more were reported present (around 60 vehicles in various conditions) in several Panzer and infantry divisions.
Beside these Panzer divisions, many more units received Marder III anti-tank vehicles: The 5th (12), 6th (9), 7th (47), 8th (12), 17th (6), 18th (6), 19th (16), 20th (24) and the 22nd (6) Panzer Divisions. As more advanced tank hunters were built, the Marder III was used to equip several infantry and infantry motorized divisions. 18th Inf. Mot. div. received 6, the 20th Inf. Mot. div. received 15, the 29th Inf. Mot.div. received 6, and the 35th Infantry division received only 2 vehicles.
It is important to note that, besides these divisions, many more received the Marder III, but it is difficult to find the exact numbers. In addition, some vehicles were used as training vehicles, which also complicates the total count.

Production

In order to start the production of the new Marder III as quick as possible, BMM was ordered by the German military officials to reuse the existing Panzer 38(t) production line, and thus save time. It was necessary to make certain changes to the production line and adapt it for the needs of the new Marder. Because of this decision, the production of the original Panzer 38(t) was reduced to a minimum and, at the beginning of June 1942, completely stopped in favor of the new tank hunter.
Production of this vehicle began in April of 1942. Monthly production was: April 38, May 82, June 23, July 50, August 51, September 50, and October 50, in total 344 vehicles. From April to July, the Panzer 38(t) Ausf.G tank chassis was used, and from July to the end of the production run in October, the Panzer 38(t) Ausf.H tank chassis with a stronger engine was used.

Advantages and disadvantages of the Marder III

The Marder III tank hunter solved the problem with the low mobility of towed anti-tank guns. It could quickly respond to any threat and quickly disengage and retreat to safety if necessary. The Panzer 38(t) chassis was mechanically reliable and was adequate for this modification. The Marder III was fairly fast, especially on the march and the steering was easy for the driver to handle.
The main gun had enough firepower to destroy any tank at that time at great distance. This was especially evident during the battles in open field in Africa and Russia. It was also a great morale booster for the infantry when they fought together.
The high profile was a big problem for the Marder III, making it a good target for enemy gunners. The armor was also quite light and offered only limited protection from small arms fire and shrapnel. Heavy camouflage and a good selected combat position were necessary for the crew’s survival, but this was not always possible or easy to achieve successfully (for example, in open fields and deserts).

The Marder’s high profile is evident here. Source: www.worldwarphotos.info
The firing position had to be changed often in order to avoid enemy return fire. By doing this, it was necessary to rise (or lower) the travel gun lock, which could take time as a crew member had to get out and do it manually. This had to be done so as not to cause damage to the gun or affect the gun calbration.
Major mechanical failures were rare, but due to the high centre of gravity, the suspension spring bolts were under high stress and they often broke. Supplies of new spare spring bolts were often not available, and this forced many vehicles to be out of use for some time.
The ground pressure was very high, if the driver did not pay attention to the environment, he could easily get the vehicle stuck in the mud. The low ammo capacity was a big issue, especially during prolonged fights as the crew could quickly run out of ammunition. A problem was also the fact that there was no adequate vehicle for the delivery of additional ammunition. Half tracks were often used for this role, but there were never enough of them available. Ammunition carriers based on tank chassis were preferred however they were used in limited numbers by the Germans during WWII.

7.62 cm PaK 36(r)

During Operation Barbarossa, the German ground forces managed to captured large numbers of field guns of different calibers. One of the gun captured was the 76.2 mm M1936 (F-22) divisional gun. After a brief assessment of the characteristics of this gun, the German were satisfied with its performance. The gun was given to the army for use under the name FK 296(r). It was at first used as a field gun, but very soon it became clear that it possessed great anti-tank capabilities.

When the German army came across the new Soviet T-34 and the KV-1 and KV-2 tanks, the 37 mm PaK 36/37 did not prove up to the task and the PaK 38 was available only in small numbers. Thus, a temporary solution had to be found and quickly. The 7.62 cm M1936 gun was modified for use as an anti-tank weapon. The changes involved adding a muzzle brake, the gun shield was cut in half and the upper part was welded to the lower part of the shield (similar to the PaK 40 two part shield), reaming-out the gun chamber to 7.5 cm caliber in order to use the standard German ammunition (same as PaK 40) and the elevating handwheel was moved to the left side. After these changes, the gun was renamed 7.62 cm PaK 36(r), and remained in use throughout WWII.

10.5cm K. gepanzerte Selbstfahrlafette IVa – Dicker Max

Nazi germany Nazi Germany (1941) SPG – 2 built

Introduction

The German Army 10.5 cm K. gepanzerte Selbstfahrlafette IVa artillery self-propelled gun was intended to be used as a long range ‘bunker buster’.
The purpose of this weapon was to fire from a long distance at a strongly held enemy fortification without being in danger of coming under return fire from its target.

Hello dear reader! This article is in need of some care and attention and may contain errors or inaccuracies. If you spot anything out of place, please let us know!

The German armament manufacturer Krupp began development in 1939, but no prototypes were available in time for the invasion of France. The French Maginot Line system of concrete strongpoints, along the border between France and Germany, would have been one of its intended targets. With the quick surrender of France, there was no longer a requirement for such a weapon.
It was then envisaged that this self-propelled artillery gun could be used in the role of a powerful long range tank destroyer. Two prototypes were built and sent to the Eastern front for battlefield trials.

The Name

This self-propelled gun is normally known by its modern nickname, ‘Dicker Max’, which means ‘thick’ or ‘fat’ Max but it was never officially called that in any wartime documentation. It did have a very large profile compared to other self-propelled guns built in 1941. It is also known by a number of other names.
Throughout most of its development, it was known as the 10 cm K Panzer-Selbstfahrlafette IVa (Pz.Sfl.IVa). The letter K stands for the German word ‘Kanone’, which means gun or cannon. ‘Panzer-Selbstfahrlafette’ translates to armored self-propelled gun mount. On 13 August 1941, this SPGs name changed for the last time. It was redesignated 10.5 cm K. gepanzerte Selbstfahrlafette (gp.Sfl.). The German term ‘gepanzerte Selbstfahrlafette’ also translates to armored self-propelled gun mount. The Panzerjäger-Abteilung 521 unit commander, Oberleutnant Kurt Hildebrandt, mentioned in his war diary that this vehicle was given the name ‘Brummbär’.

Design

In January 1941, the two finished prototype Dicker Max SPGs were driven out of the factory doors. Hitler witnessed a demonstration of their abilities on 31st March 1941 and gave his approval. If combat trials were successful, then production could begin as soon as possible. Realistically, this would not have been possible until the spring of 1942 if the production order was given following successful trials.
The K18 heavy field howitzer was a very large and heavy gun. The designers needed a strong vehicle to carry it. They chose the Panzer IV Ausf. D tank chassis, but it had to be heavily modified. The gun crew needed space to work the weapon. The Panzerkampfwagen IV engine was at the rear of the vehicle, but this was a problem. The solution the designers came up with was to move the engine to the middle of the chassis. The V-12 Maybach HL120 engine of the Panzer IV was replaced by a lighter Maybach HL 66 Pla 6-cylinder liquid-cooled engine.
The tank turret was removed. The armored engine hatches were cut away to leave a large space in the rear of the vehicle. The gun was mounted above the engine. An open topped armored fighting compartment superstructure casement was built around the gun. The sides and rear were constructed using 20 millimetres (0.79 in) thick armor.
This would stop most small arms fire and shell shrapnel. The crew were given better protection at the front. The forward glacis plate was 50 mm (2 inch) thick face-hardened armor. It was sloped at 15° from the vertical.

This vehicle was seen as a second line support weapon that used its long range to engage enemy targets and stay out of harm’s way. It was not given a hull mounted machine gun. The one that was fitted to the Panzer IV tank chassis was removed.
The designers thought it would be a good idea to replace it with a fake armored driver’s compartment on the right hand side of the vehicle, that matched the one on the left, to confuse the enemy. The crew carried three 9 mm machine pistols with 576 rounds of ammunition for use in self-defence.
An ‘A’ frame gun travel lock was fitted on the front deck to secure the gun whilst the vehicle was driving across uneven ground. The 10.5cm K18 gun could only traverse 8° to the left and right, with a depression of 15° and elevation of 10°.
The gunner and driver had to work together to bring the gun to bear on an enemy target. A large double baffle muzzle brake was fitted to the end of the barrel to help reduce the massive recoil of the gun by diverting the high pressure gasses sideways. This increased the time during which the gun barrel could be used before requiring replacement. There was storage space for only 25 rounds inside the fighting compartment.

The 10.5cm K 18 Gun

The German Army 10.5 cm schwere Kanone 18 L/52 (10.5 cm sK18 L/52) was a field gun used by Germans in WW2. The German words ‘schwere Kanone’ mean heavy cannon or heavy gun. They were often abbreviated to ‘sK’ or just ‘K’. The 10.5cm K18 was heavier than the 10.5cm M18 field howitzer because guns have longer barrels than artillery howitzers. During the vehicles development the gun was often refered to as being a 10 cm rather than the more accurte 10.5 cm designation.
Even though it had a relatively small calibre, it’s weight was 5.5 tonnes (about the same as the 15cm howitzer), making it 3.5 tonnes heavier than the 10.5cm Lfh18 light field howitzer
The 10.5cm K18 used the same Krupp gun carriage as the 15 cm howitzer because both weapons had a similar weight. It sometimes equipped the medium artillery battalion, but normally was used by independent artillery battalions and on coast defense duties.

The gun was developed late in the 1920’s by Rheinmetall. It didn’t enter production until 1933. The most important feature of the 10.5cm K18 gun was the barrel. The barrel length was 5.46 m (18 ft), or L/52, meaning 52 times the caliber. This was almost twice as long as the 10.5cm Lfh18 howitzer, thus giving it one-and-a-half times the range: 19 km compared with 13 km when firing HE high explosive shells.
Only 1,500 guns were produced. The APHE shell (Armor Piercing shells with High Explosive filler) weighed 15.6 kg and was fired at a velocity of 835m per second (2,739 ft/s). At a range of 2 km (1.24 mi), its armor piercing shell could penetrate 111 mm (4.37 in) of armor sloped at 30°. At 1.5 km (0.93 mi), it could penetrate 124 mm (4.8 in). At a range of 1 km (0.6 mi) it could penetrate 138 mm (5.43 in). At 500 m (0.3 mi) its AP shell could penetrate 155 mm (6.1 in) of armor.
Production numbers of the 10cm K18 were quite low, especially when compared to the production of the lFH18 and the sFH18. Thirty five were produced in 1940, one hundred and eight were manufactured in 1941, one hundred and thirty five in 1942, four hundred and fifty four in in 1943 and seven hundred and one in 1944.
In some official German Army reports the 10.5cm K18 gun was officially designated 10cm Kan. This can be very confusing. The actual caliber of the s.10 cm K18 was 10.5 cm (4.14 inches). The German 10 cm Kanonen originated from the WW1 10.5 cm naval gun caliber.

When the 10.5cm sK 18 gun first entered service in the German Army, it was not motorized and had to be pulled by a teams of horses. The gun weighed too much for one team of six horses, therefore the barrel and the carriage had to be towed as separate loads by two different teams.
Unlike the 10.5cm sFH 18 howitzer, however, the 10.5cm K 18 cannon was considered too large to be horse-drawn, and was therefore not found in the standard German infantry division until the divisional artillery regiments began retiring its horse drawn teams and using half tracked motorized tractor units in the middle of the war.
Panzer Artillery Regiments and later Panzergrenadier Divisions had been motorized from the outset, and one battery of the heavy battalion of these regiments was equipped with four K18 cannons for most of the war. The sK 18 was intended to be used mostly in counter-battery role; besides, due to its long range, it was more suitable to furnish fire support.
The 10cm K 18 gun fired a flatter trajectory round at a higher velocity out to a range of 19,075-meters, making it the furthest-ranging gun in the German arsenal. A typical mission would be counter-battery fire (the destruction of enemy artillery). In the long run it proved a disappointment in service, due to its relatively low shot weight of only 5.43 kg, which reduced the effectiveness of the gun considerably.

Combat Trials

In May 1941, the Panzerjaeger-Abteilung 521 tank hunter battalion was chosen to conduct combat trials with the two new prototype 10.5cm K. gepanzerte Selbstfahrlafette IVa self-propelled guns. They were used on the Eastern Front along with the two new prototype 12.8cm kan (Sfl.) self-propelled guns.
The trials did not start well. One of the 10.5cm K. gepanzerte Selbstfahrlafette IVa self-propelled guns was completely destroyed when it accidentally caught fire and the heat caused the ammunition to detonate.

Destroyed Dicker Max
In this photo of the destroyed 10.5cm K. gepanzerte Selbstfahrlafette IVa the front right track guard has been bent upwards. It looks like a mechanic wanted more room to work in as he tried to remove the vehicle’s final drive. It was probably dragged back into the woods to provide some cover, for the engineers stripping the vehicle, from Soviet air attack. (photographer unknown)
The remaining 110.5cm K. gepanzerte Selbstfahrlafette IVa fought successfully until the end of 1941. The gun barrel, in some of the black and white operational photographs, features white rings painted on it. These are ‘kill rings’, that denote how many Soviet tanks it had destroyed.
Records show that it was transported back to Krupp and rebuilt during the first half of 1942. The photograph below is of the vehicle with damage. It looks like it has lost a road wheel and suffered damage to the fourth road wheel, possibly caused by driving over a mine. It is on a railway flatback tank transporter wagon going to be repaired.
When the repair work was complete, it was returned to the Panzerjaeger-Abteilung 521 in time to take part in the 1942 new German summer offensive on the Eastern Front, called Case Blue.
Damaged Dicker Max
Notice the ‘kill rings’ have been hand painted and go all the way around the barrel on this 10.5cm K. gepanzerte Selbstfahrlafette IVa. When it returns from the factory they are more professionally painted and are only on the side of the barrel. (photographer unknown)
Battalion records of the Panzerjaeger-Abteilung 521 showed the 10.5cm K. gepanzerte Selbstfahrlafette IVa being available for Operation Case Blue. The same Battalion records for November—December 1942 do not show it on the register of available vehicles. Nothing is recorded of its fate. Normally if it was knocked out by enemy action or had a mechanical breakdown this would be recorded.
One source has stated that the surviving 10.5cm K. gepanzerte Selbstfahrlafette IVa was sent to Germany in October 1942 and rebuilt as a standard Panzer IV tank nicknamed “Brummbaer”. Is this true? Why go through this effort when you have a weapon that is destroying enemy AFVs on the frontline. It seems unlikely.

Were the trials a success?

The one remaining vehicle is known to have combat kills but, by the end of 1942, production of the high velocity 8.8cm gun was at a higher level than the 10.5cm K18. It may be argued that it was decided to concentrate on producing the anti-tank self-propelled guns that used the 8.8cm gun: these included the Nashorn, Jagdpanther and Ferdinand.

The Panzerjaeger-Abteilung 521

On the 8th June 1942, the German Army tank hunter battalion Panzerjaeger-Abteilung 521 was fighting on the Eastern Front as part of XVII Corps, 6th Army, Army Group South. Battalion records recorded that it had two companies of Marder II 7.5cm Pak 40 anti-tank self-propelled guns, one company of Panzerjäger I 4.7cm anti-tank self-propelled guns, one platoon with two 12.8m Selbstfahrlafette auf VK30.01(H) “Sturer Emil” self-propelled guns and one 10.5cm K. gepanzerte Selbstfahrlafette IVa.
The last surviving 10.5cm K. gepanzerte Selbstfahrlafette IVa disappeared from the Panzerjaeger-Abteilung 521 ‘strength reports’ in November 1942. Both “Sturer Emils” and three Panzerjäger-I SPGs and a Marder SPG are shown available for deployment. In December, only one “Sturer Emil”, three Panzerjäger-I SPGs and one Marder SPG were reported available for action when the unit was merged in a “Panzerjaeger-Verband”. It was destroyed in the Stalingrad-Area in January 1943.
There is a problem to solve. The last known photograph of the surviving 10.5cm K. gepanzerte Selbstfahrlafette IVa is dated February 1942 and has a solder dressed in what looks like Red Army winter clothing climbing on top of the vehicle. It is not known if this is a Soviet soldier or a German soldier wearing captured winter clothing. Some sources state that it was a Soviet official photographer. It is not known what happened to this vehicle after this photograph was taken.

Jagdpanther

Nazi germany Nazi Germany (1943) Tank hunter – 415 built

Historical context

After encountering heavy Soviet tanks such as the KV-1, it rapidly became apparent that the Pak 36, which formed the bulk of the German AT guns at the start of Operation Barbarossa, was inadequate. To counter the threat these tanks posed, heavier guns were introduced to the front, including the 7.5 cm (3 inch) Pak 40 and, more importantly, the 88 mm (3.5 inch) Pak 43. The 88 mm (3.5 inch) Flak, on which the Pak 43 was based, had been used in ground support since the Spanish civil war and had proven to be very proficient at taking out tanks. So it’s no surprise the decision was made to mount it onto a tank chassis.

Hello dear reader! This article is in need of some care and attention and may contain errors or inaccuracies. If you spot anything out of place, please let us know!

The resulting tank was the Hornisse (later known as the Nashorn), which had a Pak 43 mounted onto a Panzer III/IV chassis. Despite having a high silhouette and very little armor, it proved more than adequate, being able to take out tanks at ranges of over 3000 m (3280 yards).
Another tank destroyer using the Pak 43 was the Ferdinand (later known as the Elefant). After losing a design contract to Henschel, Porsche had 100 Tiger P chassis which couldn’t be equipped with the Henschel turret, since they were reserved for the Henschel Tiger tank. In 1942, the order was given to convert the remaining chassis into tank destroyers, which were to use the Pak 43. The Ferdinand first saw use in the Battle of Kursk, where it could easily take out enemies from long range. But when it advanced, the flaws became apparent. The lack of close range defense made it an easy target for Soviet infantry, that could near the tank. to throw Molotov cocktails onto the engine deck. Its heavy weight also made it difficult to cross most bridges of it’s era, and the poor Soviet infrastructure made navigating near impossible in certain places.
It became clear that the German army was in need of a tank destroyer that offered decent mobility without sacrificing armor, and vice versa. And as such, the Jagdpanther came to be.

The hunting Panther

Front-left view of the Jagdpanther
The Jagdpanther is one of the most iconic tank destroyers of World War 2. Based on the Panther chassis, the famous tank destroyer was produced from 1943 up until the end of the war in 1945. Mechanically more reliable than the Ferdinand/Elephant and the Köningstiger, armed with the 88 mm (3.5 inch) Pak 43 “Panzerknacker” and with 80 mm of 55 degree sloped armour (this presented 138 mm of thickness of armour to a shell fired horizontally at the front of the Jagdpanther) it was a formidable opponent for any tank at the time. During the war, over 400 tanks were produced, seeing action on both the Eastern and the Western European fronts. After the war, captured Jagdpanthers were used by the French army, along with Panthers and other German tanks, up until the 1950’s. Overall,the Jagdpanther was a great mix of mobility, firepower and armor. Today, only 10 of the tank destroyers are left, spread across various museums worldwide.

Development history

Design

When the Pak 43 was designed, it was originally meant to be towed into battle, but it soon became clear that the anti-tank gun was very unwieldy to transport in the field. As a result, the Wehrmacht started looking for a self-propelled platform to mount the 88 mm (3.5 in) gun onto. The solution was found on August 3rd, 1942, when the Heereswaffenamt (the agency in charge of R&D for the German army) decided to mount the Pak on a Panther chassis. Krupp was awarded the design contract, but was unable to deliver the design drawings by January 1943, and so the project was handed over to Daimler-Benz. Krupp, however, remained responsible for the production and delivery of the Pak 43, the main armament of the Jagdpanther. In the first designs, the tank was named the “88mm Sturmgeschutz.”
The final design was presented to Hitler on his birthday, and subsequently accepted by the Heereswaffenamt in May 1943. As production started on the first models of the Jagdpanther, it became apparent that there was a shortage of workspace in the Daimler-Benz factory. That, combined with Daimler-Benz not being able to produce the contracted amount of Panthers, lead to production being handed over to MIAG, a Braunschweig based company. A pre-production model was presented to Hitler on the 20th of October, alongside a model of the Tiger 2 and the Jagdtiger. November that year, mass-production of the Jagdpanther was authorized. When it entered German Army service it was given the designation Sd.Kfz.173.

Production

Jagdpanthers on the factory floor
The first Jagdpanther meant for service was delivered in December 1943, with production increasing to 10 tanks per month in April 1944. Delays in production were mainly due to improvements being implemented. Strengthened gearboxes and intermediate gears were installed. Jagdpanther production was also slowed down due to bombing raids and lack of workmen. By the end of June 1944, only 46 of the tanks had left the factory floors, barely enough to equip one Schwerer Panzerjäger unit. This was far from the original 160 planned vehicles, which would have been enough to equip 3 units and have some left for testing and training.
The MIAG firm complained about the lack of workmen, and as such was sent 320 men from the Panzerjäger replacement unit. This managed to boost production to 20 tanks a month in September 1944. Neither the OKW, nor the Heeresamt were happy with the production numbers and, as a result, two other companies, MHN & MBA, were contracted to produce the Jagdpanther. This increased the total output to 67 tanks for December 1944.

Armament

The Jagdpanther was equipped with the fearsome 88 mm (3.5 inch)  Pak 43. Based on an anti-air gun, the 88 mm (3.5 inch) soon turned out to be more than adept at taking on an anti-tank roll. Accurate at over 3000 m (3280 yards) and with a muzzle velocity of over 1000 m/s (3280 ft/s), the 88 mm (3.5 inch) gun has more than earned its reputation as one of the best anti-tank guns of the war.
The Pak originally featured a monobloc barrel, but due to the rapid wear of the high-velocity gun, the decision was made to replace it with a dual piece barrel. Although this didn’t reduce wear, it did make replacement easier. The main gun was able to fire different shells, ranging from the armor piercing PzGr. 39/43 and PzGr. 40/43 to the high explosive Gr. 39/3 HL.
The Jagdpanther carried 60 rounds of 88 mm (3.5 inch) ammunition, 1200 rounds for the coax hull-mounted gun and two MP40’s with 384 9×19 mm rounds. With the introduction of the Nahverteidigungswaffe (close range defense weapon), it was possible to launch projectiles near the tank without endangering the crew, and so 16 grenades were added to the inventory. However, this weapon couldn’t be built into most of the Jagdpanthers before June 1944, due to a shortage of the weapon. As a result, earlier models of the tank have the opening in the roof sealed with a circular plate which was held by screws.

Armor

As the Germans improved their armor, so did the Allies. As the war progressed, bigger and heavier guns were being developed by the Allies, capable of shooting shells of ever-increasing penetration. To counter this, tanks were designed with thicker and sturdier armor, with the Jagdpanther being no exception. Meant to be able take on other tank destroyers, the Jagdpanther’s frontal upper armor was a single, 80 mm (3.15 inch) thick wall of steel under an angle of 55°, with the lower frontal armor being 60 mm (2.35 inch) at an angle of 60°. This resulted in a formidable effective armor thickness of ~140 mm (5.5 inch) for the upper plate and ~90 mm (3.5 inch) for the lower plate, guaranteeing protection from all but the heaviest of guns.
The gun mantlet was just as tough as the frontal armor of the Jagdpanther. A 100 mm (3.9 inch) thick ‘saukopf’ (pighead) mantlet was installed on the gun. The sides of the superstructure of the tank had 50 mm (1.97 inch) of armor, while the lower sides had 40 mm (1.57 inch) of armor. The roof and the floor were between 16 (0.63 inch) to 25 mm (1 inch) thick.

Mobility

Jagdpanther driving up a slight hill
The production model of the Jagdpanther weighed in at 46 tonnes, making it one of the heavier tanks fielded by the German army. The drive train was the same as the Panther aside from the engine and the heavier transmission. It was powered by a 12 cylinder Maybach HL 230 P30 23.1 liter V12 gasoline engine, which would give it an effective range of 160 km (100 miles) and a top speed of 46km/h (28.6 mph), making it as fast as contemporary Allied medium tanks such as the M4 Sherman, despite the latter weighing 15.000 kg (33070 lbs) less.

Crew

Inside the Jagdpanther there was a 5 man crew consisting of the commander, driver, gunner, loader and radio operator, with the latter doubling as machine gunner. The two hatches at the top of the tank were for the commander and the loader, with the hatch at the back serving as an entrance for the crew and to replenish ammunition.
On early models, the driver used two periscopes to see ahead, and 5 pistol holes which could also be used to observe the surrounding battlefield, but the latter soon turned out to be more detrimental to the strength of the armor. In later models the holes were removed and the left periscope was welded over, being filled with a 15 mm (0.59 in) thick plate. The commander and loader had four periscopes available to survey the surrounding area, two rigid, and two capable of turning.
The Jagdpanther was provided with a 10 Watt Fu 5 transmitter and a 2 Watt Fu 2 receiver radio. Command vehicles received the long range 30 Watt Fu 8 radio set.

Modifications

As the war went on, several additions and adjustments were made to the Jagdpanther.
January 1944: The pistol ports , which weakened the overall hull strength and had become unnecessary with the installation of the Nahverteidigungswaffe, were removed from the tank.
February 1944: The left driver periscope was removed and welded shut with a 15 mm (0.59 in) piece of steel and a towing coupling was welded to the back servicing plate. To make space for this, the winch was moved up to between the exhaust pipes.
Earlier Jagdpanther still used the Panther Ausf.A engine cover, with the difference being the air intake was made smaller to fit on the tank destroyer. Where the Panther’s radio antenna was attached to the hull of the tank, the Jagdpanther’s antenna was mounted on the back of the superstructure, next to the rear hatch. This left a hole in the engine cover, which was covered with a screwed-on plate.
May 1944: The monobloc gun was replaced with the two-piece gun, facilitating replacement of the worn barrel.
June 1944: A mount for a small 2-ton crane was planned for the roof of the vehicles.
The gun mantlet was changed so that a screw was at the top of the cast piece.
Later variation of the Jagdpanther, note the 'mushroom' mount for the crane and the Nahverteitigungswaffe
Note the ‘mushroom’ crane mount towards the back of the casemate, and the Nahverteidigungswaffe to the front and left of it.
September 1944: The OKH ordered manufacturers to stop using the Zimmerit protective coating on the tanks.
October 1944: Sheet metal pipes were installed over the exhaust, on the account of them glowing at night, possibly giving the tank’s position away.
The leading wheels of the Jagdpanther didn’t clean themselves, and as mud and snow gathered, tracks got thrown. New leading wheels of a bigger diameter were developed, reducing the amount of tracks thrown.
December 1944: The Jagdpanther started using the new type of engine cover provided for the Panther and “flame-destroyer” exhaust mufflers are installed, preventing mixtures of fuel and air in the exhaust from igniting.

Derivatives

In late 1944, plans had been made to mount the 128 mm (5.04 in) Pak 80 onto the Jagdpanther chassis. The new vehicle, known as the Jagdpanther mit 12.8 cm PaK 80, would have had a rear-mounted casemate and weighed in excess of 50 tonnes. The project never got past the blueprint phase and got shelved before the war ended.

Jagdpanther in action

The Jagdpanther mainly saw action one the Western front from its deployment in March 1944, with deployment to the Eastern front only occurring from January 1945 onwards. The first unit to receive the new Jagdpanther was the schwere Panzerjäger-Abteilung 654. Each Jagdpanther Kompanie was scheduled to receive 14 of the tanks destroyers, and an additional 3 command tanks for the battalion headquarters. Due to production problems, it wasn’t possible to bring the 654th to full strength before being sent to the front in June, 1944.

First blood

Jagdpanthers in France
The first action the Jagdpanthers saw was on the 30th of July, when they engaged a squadron of Churchill tanks near St. Martin de Bois. In a two-minute action, three Jagdpanthers managed to take out eleven Churchills, before an additional squadron of Churchills rushed in to help. The 6th Guards tank brigade reported the capture of two Jagdpanthers, which had been left behind due to track damage. Nonetheless, this encounter showed the strength of the new tank destroyer and helped cement its reputation as a threat to any tank that encountered it.

Ardennes Offensive

In preparation for the Ardennes Offensive, the OKH had planned to fully equip five tank hunter battalions with Jagdpanthers. Three of the five units were already at the front and as such weren’t at full combat strength. Due to supply problems, only 27 of the 56 planned Jagdpanthers made it to the battalions before the start of the offensive, with only 17 of them being operational.

Eastern front

Many of the tanks that were sent to the Eastern front weren’t destroyed by Soviet troops, but at the hands of their crew. The main problems that plagued the Panzer divisions were a lack of spare parts, fuel and delays in the production process that prevented more Jagdpanthers from reaching the front. In January 1945, the 563rd s.H. Pz.Jg.Abteilung managed to take out 53 tanks whilst only losing four Jagdpanzer IVs and one Jagdpanther to enemy fire. The bulk of their losses were credited to tanks being blown up lest they fell into enemy hands. For example, a stunning 12 Jagdpanthers and 17 Jagdpanzer IVs were destroyed by their crews in the 563rd alone. The rapidly deteriorating situation meant that many of the Jagdpanther crews sent to the front in 1945 had received little or no training, which reduced the already impaired effectiveness of the tank destroyer battalions.

WW2 German Tank Destroyers

7.5cm Pak 40 auf Raupenschlepper Ost (RSO)

Nazi Germany (1943) Tank destroyer – 80-90 est. built

From Hauler to Fighter

As the German army faced ever increasing numbers of Allied armour, more ways were found to place anti-tank weaponry on already existing chassis, in order to try and counter the Allied numerical superiority. The Raupenschlepper Ost (RSO) was no exception to the armed conversions that were built upon so many German vehicles at the time.

The decision was made in 1943 to take the well proven battle tractor and place a Pak 40/4 on its back, in order to provide more mobile anti-tank capabilities on the front line. After only a very limited amount were produced, it was made clear that this was one conversion that was not a successful fighting vehicle.

Hello dear reader! This article is in need of some care and attention and may contain errors or inaccuracies. If you spot anything out of place, please let us know!

Origins in the mud

The development of this vehicle is directly linked to the development of the RSO tractor built by Steyr from 1942 to 1945. This tractor was developed to meet the needs of the Wehrmacht for bringing supplies and weapons to the front lines in the poor conditions that were met on the Eastern front. Many of the battles there were far from any road, and if roads did exist, they were often in very poor shape, especially in spring.
It was soon found that existing vehicles were not satisfactory for bringing supplies and the newer larger anti-tank weapons through this adverse terrain, thus the designs for the RSO were created. By 1945, about 27,000 RSO tractors had been produced.

Development of an armed version of the RSO began only a few months after the tractor was in service. It was found that, due the rough nature of cross country driving, the sights of a gun being towed behind an RSO would be knocked out of calibration. Due to this, experimentation was undergone with mounting several guns on the bed of the RSO, including 75 mm (2.95 in), 105 mm (4.13 in) and 150 mm (5.9 in) weapons.
The intent would be to unload the gun at the front with a collapsible crane. This would allow for quick transport of weapons, but would still require time for the unloading and set up of the gun, and did not allow for any firing of the weapon while still mounted on the tractor. Though a few trial vehicles were made during these tests, none entered mass production
In the summer of 1943, the need for gun mounted on an RSO that could fire without having to remove the gun from the chassis was seen. A version made with a low silhouette cab (with only lower body protection for the driver and co-driver), along with collapsible sides on the cargo deck, was designed to carry a 75 mm (2.95 in) Pak 40/4 gun that could traverse 360⁰. When Hitler was shown this design, he ordered that it be put on high priority for production, as he saw in it an excellent balance of mobility, firepower and economics, which would provide an excellent tank hunter to the front.
On October 1st 1943, a prototype was presented to Hitler, after which production plans to produce 400 a month was put in place, despite there being no combat trials yet. However, very few were ever made. It is unknown how many of this RSO variant were produced, but it is generally believed to be less than 100.
Some information exists showing that Steyr was designing a new prototype immediately after the first design was approved for production, under the name “PzJag K43”. This would be a new generation of RSO tank killer that would have mounted the larger Pak 43, as well as have a wider chassis with a more powerful and less noisy engine. However, all work was halted in late 1943, when Steyr was ordered to stop working on tracked vehicle designs.

Use in combat

The first deployment of this vehicle was with Army Group Center in January 1944. Some were sent to the 1st Ski-jäger Brigade, and some were sent to Army Group North, to Armee-Pz. Jägerabteilungen 751 and 752. In the 1st Ski Jäger Brigade, the RSO with Pak 40 was incorporated into the 13th Panzerjäger-Flak company, where it was deployed in 2 platoons with an infantry escort platoon.
Inside an RSO Pak platoon there were 3 RSO Paks, 1 supply vehicle, a Kübelwagen for the platoon commander and a Kettenkrad. In action, this vehicle was said to be less than desirable. It was slow, noisy and the engine had a tendency to overheat in warm weather. The lack of armor and high silhouette was also an issue, as many crews were lost when they attracted fire of any kind.
The small fighting platform made it difficult to work in an effective manner, and the floor lockers for ammunition storage were difficult to open when the weapon was in use. The vehicle earned the nickname “Rollender Sarg Ost”, a play on the RSO abbreviation. This nickname translates to “rolling coffin east”, reflecting the thoughts of the soldiers who operated it.
This fully tracked, lightweight vehicle was conceived in response to the poor performance of wheeled and half-tracked vehicles in the mud and snow
