Geschützwagen E 100 (Fake Tank)

German Reich
Self-Propelled Gun – Fake

Since the Second World War, the weapons of Nazi Germany have given rise to great myths and legends, many only lightly connected to historical reality or physical plausability. The famous Tiger tank or the massive Maus have sparked massive interest amongst amateur and veteran historians alike. This phenomenon can be seen most prominently within the military modelling community, where the surplus of pieces and time removes all limits for those ensconced by the German military’s real or imagined might. Naturally, many unique creations have been made, some completely disregarding any historical or technical factors, being part of a hobby for personal enjoyment, and not for serious historical discourse. One such creation is the Schwerer Geschützwagen Löwe 24 cm (Eng: Heavy gun carrier Lion 24 cm) created by a German modeller in the 2000s. Over a decade later, the video game company Wargaming was looking for a German self-propelled gun to fill the spot for the Tier X German Self-Propelled Gun (SPG) line in their game World of Tanks. The modeller’s abomination suited their needs.

The Model

The creator of the model is Sebastian Nast, who converted and merged a Dragon Models 1:35 E 100 model kit and a Precision Models 24 cm K4 resin kit. He did, however, make drastic changes to those parts. The Schwerer Geschützwagen Löwe is essentially a lengthened E 100 hull (one extra set of overlapping wheels per side) with the engine moved to the middle, behind the driver. The gun, a 24 cm K 4 Sf, manned by a crew of 8, is housed inside a large open-topped superstructure heavily inspired by the real Geschützwagen Grille 17/21. As a matter of fact, the entire model seems to have been inspired by the Grille, being a ‘what-if’ even larger variant. Interestingly, the creator provided a short fictional “history” of the vehicle. Its translation from German:

“As early as 1942/43, the Army Weapons Office made a demand for heavy and very heavy self-propelled guns. By the end of 1944, the Grille self-propelled gun, based on an extended Tiger II B chassis, was almost ready for serial production. The 17cm K 44 and/or 21cm Mörser 18 were intended as armaments. After detailed tests, it turned out, however, that these armaments did not bring satisfactory results. Therefore, at the beginning of 1945, the demand was made to install the new 24cm K 4, which had been newly developed in 1944 and which had made a great impression during firing attempts, in the new self-propelled gun. The Grille chassis, however, could not support this armament. It was planned that the new self-propelled gun should be based on the new E90 / E100 chassis. Codename for this project was Hummel/Wespe. Army introduction was planned for 1946 at the latest. Due to the events of the war, however, this project did not get beyond the drawing board stage. The first preliminary studies are said to have been very promising…”

The modeller provided a series of images, showing the SPG next to a Grille model, and being loaded by a half-track with ammunition. Nast calls it a “historical-logical reconstruction” and the most probable variant if the E 100 hull would have ever been used as a SPG. You can find more images of the model and a short text by Nast himself on the model here, written in June of 2001.

The model was put up for sale on Ebay by seller ‘Goldenstern114’ in the summer of 2020 and sold that same October for €176.

Historical elements

Like most such scratch builds, the Schwerer Geschützwagen is based on some form of reality. The E 100 chassis was, of course, a real thing, that was partially built and completed by Adler in January 1945 at Hauestenbeck, where the Allies would later find it in early April 1945.

The gun, the 24 cm K 4, was also historical, but never left the drawing board and was certainly never tested, as Nast claims. Regardless, it would have been too big to fit, even in the extended E 100 hull. There were drawings of it fitted on three Tiger heavy tank chassis, or on a chassis similar to the Gerät 040/041, and even then, in an open fashion, similar to that of a railway gun. The K4 was to replace the K3 cannon and, in 1941, a contract was given to Rheinmetall-Borsig and Krupp to develop the gun. It required high mobility, a projectile weight of 160 kg and a range of 48/49 km. The barrel length was 17,280 mm (L/72) or 16,000 mm (RhB Special Panzer). The towed piece weighed 65,500 kg when transported, and 55,000 kg combat weight.

Unfortunately, the Precision Models resin kit does not seem to remotely resemble the plans of the real weapon. Nast enlarged the weapon, but it is still far off, and looks more like the 24 cm Kanone 3.

There were plans to make a self-propelled assault gun out of the E 100, namely the 15/17 cm Sturmgeschütz auf E 100 Fahrgestell, an extremely well-armored vehicle meant to take on heavy Allied tanks and fortifications from long range, but it never went past mock-up stage. Apart from blueprints showing the gun mantlet and mount, everything else has been lost.


Judging something for more than it actually was meant to be is never a good thing, but for the sake of the argument, a quick analysis of the vehicle can show how infeasible the design would have been. Firstly, the chassis still keeps the E 100 levels of protection, with a maximum thickness of 200 mm, and the heavy side panels, completely useless considering the almost paper-thin gun housing and open-top. Also, the long-range of the 240 mm K 4 cannon would have made any armor pointless, as it would fire from far behind the frontline.

Nonetheless, the weight of the vehicle was still an estimated 137 tonnes. The engine, an unspecified 1,500 hp Maybach V12, would have propelled the SPG at a whopping 42 km/h, a completely exaggerated number. The E 100 tank, weighing less than the SPG, would not have been able to reach this speed. Combined with the incredible strain on the transmission and destructive ground pressure, the vehicle would have been a mechanical disaster, unable to be produced by a struggling Germany in 1945. German heavy tanks at half this weight and less struggled mechanically, let alone something of this size.

Nonetheless, the Schwere Geschützwagen was just an interesting model, with a moderately sensible ‘history’, albeit exaggerated in its mechanical aspects. However, this is nitpicking when discussing an amateur model kitbash.

World of Tanks

Things took a weird turn when Wargaming needed a vehicle to fill their top of the line Tier X spot for German artillery. The lower tiers are filled in by historical vehicles, such as the Hummel, G.W. Panther or Grille 17/21, but at tier VIII and X, Wargaming’s research team seemed to struggle. Thus, two fake vehicles were introduced, the G.W. Tiger P and G.W. E 100. While the G.W. Tiger P is a lengthened Tiger P hull with a Geschützwagen Grille casemate, probably a Wargaming invention, the G.W. E 100 is heavily inspired by the Schwere Geschützwagen Löwe model.


Wargaming shortened the SPG back to the regular E 100 hull size, but did keep the rear overhang and most other visual aspects of the original model, like the gun shield and camouflage net holders. They did change the other performance aspects for game balancing. Interestingly, World of Tanks also provides a false history of the G.W. E 100, however, it never mentions it as being fake.

“Project for a 210 mm mortar on the chassis of the E 100. The vehicle was never produced.”

Most importantly, the gun was changed. In the game, it now has a ‘21cm Mörser 18/2’, a fictional name for the real 21 cm Mörser 18, but with the slightly changed name to differentiate between the two, as the latter is present in lower tier vehicles. The real Mörser 18 was a replacement for the 21 cm Mörser 16 from WWI. It had a weight of 16.7 tonnes, a range of 16,725 m, a muzzle velocity of 550 m/s and a High Explosive (HE) shell weight of 113 kg. The fictional vehicle can carry 30 rounds. There is an openable port on the front of the superstructure, which was probably meant to allow the use of a direct fire sight. A large gun crutch is present at the front of the top of the hull.

The much more rational World of Tanks model, but altogether an unnecessary mongrel, which can come off as something real.

The engine and other performance indicators were also changed, the engine being a Maybach HL 234 TRM P45, with a 900 hp output. This was a real engine that was hoped to reach up to 1,200 hp, so this variant is in line with historical reality (the project failed to reach the desired engine power). The engine has been moved from its rear position to the center of the vehicle, similar to the Jagdpanzer E 100 vehicle from World of Tanks. This was a common change for German artillery SPGs, also being a feature of the Hummel, Wespe and Grille Ausf.M. The transmission remained at the front, as on the regular E 100. The exhausts were moved to the front of the superstructure, an interesting location. In game, the G.W. E.100 can reach a theoretical top speed of 40 km/h, again probably overly optimistic for the transmission, suspension and engine, although the vehicle usually drives at much lower speeds.

In terms of weight, it is 87 tonnes, giving it a hp/tonne ratio of 10.34, with a well-armored hull, with 80 mm at the front, 50 mm at the sides, and 40 mm at the rear. This is significantly less than on the real E 100 tank hull, which had 200 mm of angled armor at the front, 120 mm at the side and 155 mm at the rear, so this fake SPG version would have been based on a new-built chassis, not on the already built E 100 hull from Adler. There are 60 mm thick armored skirts on the sides, originally designed for the E 100. These significantly improved the protection over the side and tracks, which were otherwise rather thin, at least compared to the rest of the tank, and flat. However, these are notably useless for a long-range artillery SPG and would represent dead weight. They were probably added in because they are a distinctive part of the E 100 look, and not for historical purposes. Two tow hooks are present on the front of the hull and another two at the rear.

The crew also dropped to 6 (commander, gunner, driver, radioman, and two loaders), with the driver and radio operator in a different compartment in the front of the vehicle, separated from the fighting compartment by the engine. The driver has a single periscope pointing toward the front, right in front of his hatch. There was no hull machine gun on the E 100 or on this vehicle. A single Notek lamp is placed at the middle of the front glacis. The rest of the crew is placed in the rear superstructure which they can access through a double door at the rear, which would probably have been kept open during firing in order to allow ammunition resupply from ammunition half-tracks. The large metal plate present at the rear of the Grille 17/21, meant to assist with turning the vehicle faster when deployed, is notably absent from the G.W. E 100.

Historical Alternatives

By now, fake tanks are more common than should be acceptable in a game that variously styles itself as realistic, historical or accurate. In the early days of World of Tanks, such fake vehicles used to be reserved only for spots that could not be filled with historical vehicles. Oddly though, there are real German designs that could fill in the spot for both the G.W. Tiger P and G.W. E 100. Walter Spielberger mentions in his book ‘Tiger and its Variants’ of self-propelled guns built using Tiger elements (perhaps the Grille chassis itself) armed with 305 mm and 420 mm Czechoslovak Škoda mortars. Alternatively, the 30.5 cm L/16 auf Sfl. Bär, armed with a 305 mm and designed by Krupp in 1943, also used Tiger components, despite being meant as a heavy assault mortar. Why these were not implemented instead, is hard to say.

There were rumors in 2013 that a second German artillery branch would be added, including the Sturmtiger and eventually the Bär at a high tier, which may have been the reason why these vehicles were not used. The rumors have not yet materialized. Other rumors also claimed that Wargaming was replacing the G.W. E 100 with the 30.5cm / 42cm Schwerer Granatenwerfer auf Selbstfahrlafette. While the two variants differed a little, they were largely identical. Developed at Pilsen in early 1945, they weighed between 55 and 65 tonnes. Most likely discovered by Yuri Pasholok, Wargaming historian at the time, it is not clear why they have not replaced the G.W. E 100. Ultimately, Wargaming never has and most likely never will replace the G.W. E 100 or the lower tier fake G.W. Tiger P because of the controversy surrounding self-propelled guns within World of Tanks.

Starting off as a typical model scratch built by a modeler, the G.W. E 100 has become an iconic fake tank due to its almost decade-long existence within World of Tanks. Even though it is a more ‘innocent’ fake, it is still a fabrication that is here to stay because of Wargaming’s satisfaction with how it fits into the German artillery line, and their lackluster care and attention to historical realism, especially nowadays, when entire tech tree lines are falsifications.

E 100 Ausf.B (Henschelturm or Rinaldi’s Turret) (Fake Tank)

German Reich (1944)
Superheavy Tank – Fake

The engineering prowess and military might of Nazi Germany still fascinate many, from young amateurs to veteran historians, almost a century later. The nearly legendary stories of super-heavy tanks, laser weapons, and flying saucers leave many to wonder what could have happened if the war lasted longer. The E 100 is just one of those examples. Its super heavy unfinished hull and its lack of turret invites enthusiasts to let their imagination loose.

One of the most well-known examples of such creations is the one made by modeler Michael Rinaldi, who scratch built a turret for a Dragon E 100 model sometime before 2002. The skill and quality of the model quickly made it popular. However, things took a strange turn in 2008, when Chinese model company Trumpeter released an almost identical copy of Rinaldi’s model.

The creator and the model

Michael Rinaldi is an American modeller who now owns Rinaldi Studio Press, where he publishes books on building, painting and weathering scale models. It was in the early 2000s when he used a Dragon models E 100 1:35th scale kit to build an E 100 model. He opted to not use the realistic Maus turret that came with the kit, but rather to scratch-build his own ‘what-if’ 1946 turret.

He closely inspected the construction and designs of late-war German turrets to make it as realistic as possible. The shape and construction form were taken from the Schmalturm turret, but lengthened, taking in consideration the extra size and recoil of the much larger gun and thicker armor. Similarly, on each side of the turret, there are rangefinders and, on top, a periscope enveloped in an armored shroud. The cupola was also placed on the left side of the turret, with a night vision device.

Rinaldi has explained before that he used whatever materials he could find for the build, i.e. the mantlet is made out of a pen cap. The barrel is from an Eduard 12.8cm proposed Jagdtiger gun through which Rinaldi wanted to showcase the L/66 gun, the infrared device came from a Tamiya kit, a cupola was a resin Panther II one, and the rangefinders were from a Dragon kit. The turret itself, the face detail and mantlet are mostly from brass and styrene.

The modeller never wrote an alternative history story or background, being satisfied with simply dating the supposed vehicle to “Summer of 1946”.

As previously mentioned, the modeler never discussed any made-up history or any specific mechanical details and specifications. The hull was unchanged from the standard Dragon E 100 model, with the exception of the addition of a machine gun mount at the front of the hull, to the right, similar to the Panther or Tiger II, and the removal of the hollow side armor sections.


The creator equipped the model with a new 12.8 cm L/66 gun, dropping the 15 cm gun that came with the original Dragon kit. This is somewhat historical, as the 15 cm gun was eventually dropped in favor of a 12.8 cm gun, but it was the KwK L/55, not L/66. Rinaldi probably went with the proposed Jagdtiger gun simply because he could find barrel parts for it. The Jagdtiger was also equipped with the L/55, but was proposed to fit the L/66. Rinaldi could have used this information to envision that, if the war had carried on, heavy tanks and tank destroyers would be equipped with the L/66. The most noticeable difference between the two guns was the L/66 longer barrel, but also a redesigned breech. The 12.8 cm PaK 44 guns used two-piece ammunition. Even so, only 40 rounds could be stowed in the Jagdtiger, suggesting that not many more would fit in the E 100.

Turret and components

The so called ‘Ausf.B’ turret fitted on the model was an enlarged version or combination between the Schmalturm and Tiger II Ausf.B turret (hence the name). While it mostly sticks to traditional German turret designs, it has a peculiar design in which the frontal armor plate is intertwined with the side armor plates. Normally in German tanks, the plates would fit into another with cutouts, like puzzle pieces. However, Rinaldi extended the length of the side armor plates. Why this was done is unclear, as it would decrease the strength of the armor plates.

Which rangefinder would be used is also unclear. It is very likely it was the E.M. 1.32 m stereoscopic rangefinder. It would have had a 15x magnification capacity, and 4 degrees of vision. The acronym stands for ‘Entfernungsmesser’ and it simply translates to rangefinder. It was to be built by Zeiss, with development ending in April 1945 and production to start in July of the same year. It was originally intended for the Panther Ausf.F. Predictably, none were built. It makes sense that, if the war had lasted for another year, either it, or an enlarged version, would have made its way on such an E 100.

The model features two infrared (IR) night vision devices. One is mounted on the top of the hull for the driver, and one on the commander’s cupola. This setup was baptized ‘Solution B’, allowing both the commander and the driver to see in the dark. The devices were the FG 1250. They consisted of a 200 watt infrared headlamp and an IR receiver, which converted the IR light into visible light. It had a maximum range of 500 meters, but realistically it might have been lower. When fixed on the commander’s cupola, it could be pointed forwards and turned along with the turret, or be turned 360 degrees independently. The commander’s hatch could not be fully closed, as the equipment required power cables connected to an energy source (either battery, generator or the tank’s own electric power supply). In the Panther, this meant the removal of 3 rounds. It can be predicted that, if an E 100 would have fit such a device, there would most likely be enough space, and the hatch issue would also be fixed.

The armor of the turret is most likely the same as that of the Maus II turret, proposed for the E 100 in 1944. It had 200 mm of armor at the front, 80 mm at the sides, 150 mm in the back and 40 mm on top. The Ausf.B turret does seem smaller and has dropped the 75 mm gun, still present on the Maus II turret. This might have allowed for thicker side armor, of around 100 mm.

The hull is almost identical to the standard E 100 hull found by the British in 1945. The only differences are the addition of the machine gun port on the frontal plate and the absence of the side plates. While it would create a weak spot in the frontal protection of the tank, the machine gun would have added some degree of protection against infantry, who could pose a huge threat to such a large tank with handheld anti-tank weapons. The rest of the tank seems to be lacking in machine-gun firepower, with no co-axial or cupola-mounted machine guns.


Rinaldi’s model was mostly known within limited modeling circles and forums. In the early 2000s, social media was in its infancy and the modeling hobby and interest in tanks were not as popular as it is today. Everything changed when Chinese modeling company Trumpeter released a 1:35 scale model of an E 100, called “German E 100 Super Heavy Tank”, in 2008. The problem was that both the boxart, created by Vincent Wai, and the model itself, were almost direct copies of Michael Rinaldi’s model. The boxart even features Mike’s addition of a hull-mounted machine gun, but the idea was dropped on the model kit itself. Other than that and a few other minor alterations, it is a direct copy of Rinalid’s model.

Here is one of many of Rinaldi’s comments on the topic:

“This idea and model of the E 100 Ausf B is [sic] my creation. It did not exist at any point in time in history, not on paper, never – I made it up. I used my best guess for what something like this might have looked like. This is the third time my model and idea has [sic] been copied for commercial sale and I never gave Trumpeter permission. What is that saying about the sincerest form of flattery”
-Michael Rinaldi, creator of the E 100 Ausf.B
Originally, Rindaldi seems to have accepted Trumpeter’s usage, possibly hoping for crediting or monetary compensation, but quickly felt the burn of Trumpeter’s unwillingness and indifference to the issue.

“Trumpeter stands to gain from my idea and efforts without any due notice, compensation or credit to the original idea, or to the authenticity of the historical background behind this turret and armament combination, which is completely hypothetical.”

-Michael Rinaldi, creator of the E 100 Ausf.B

Trumpeter never mentions Rinaldi or that the vehicle’s turret is fictional. They even proceed to add a short text on the box with generic information about the E 100, omitting the usage of a fake turret. Their box description goes as follows:

“Super heavy tank as an alternative to the Maus, it used a modified Maus turret with the 150mm KwK with plans to upgrade to the 170mm KwK later. Development of the E 100 started in June 1943 & continued steadily until 1944 when Hitler stopped all development of super heavy tanks. But even though, three engineers carried on the work at low priority & by the end of the war they managed to nearly finish the first prototype which only needed the turret. The only prototype was sent to England after the allies captured it & scrapped post-war.”
-Trumpeter information on E 100 model box

Despite Rinaldi’s complaints and a potential lawsuit (this has been mentioned in online forums but not confirmed by Rinaldi), Trumpeter released an identical kit, in 1:72 scale, 8 years later, in 2016. Both kits sold well. In fact, they have sold so well that the Trumpeter E 100s are a “must have” on the shelves of many modellers. Unfortunately, their erroneous equipping of a fake turret and thievish usage of Rinaldi’s creation induced many to confusion. Self-proclaimed historians, amateurs and enthusiasts have been misled by this, with many claiming this turret was designed by Henschel for the E 100, hence the frequent usage of the name Henschelturm. This has sparked further fantasies, such as the E 100 Adlerturm.

The confusion has made others to commit the same mistakes. Chinese modelling company Modelcollect has also made a 1:72 kit of the same model in 2016. Likewise, Czech Mobile video game company Krieg Games R.S.O. has implemented an E 100 “Henschel” in their game, Armored Aces.

Trumpeter has not stopped there with their fake kits. They have released kits of the E 100 Krokodil/Salamander and others, treating them as real projects. It was only in 2017 that Trumpeter finally released a model kit with the E 100 and the historical Maus II turm.


Not much had been heard of Rinaldi’s model until sometime in 2020, when photos appeared of the model, all stripped of paint, potentially ready for a second paintjob. Meanwhile, Trumpeter’s iconic model kits continue to mesmerize unknowing modellers, while its story and the ties to Rinaldi’s model have been mostly forgotten, a faint memory in the minds of veteran internet enthusiasts or wiped completely with the slowly disappearing Armorama forum pages, dating from almost two decades ago.

Jagdpanzer E 100 (Fake Tank)

German Reich (1944)
Tank Destroyer – Fake

The E 100 super heavy tank is one of the most fascinating tanks of Nazi Germany. While it does not have near-mythical combat legends of the Tigers or the sheer weight of the Maus, its partially built hull was impressive enough to cement it into tank history for decades to come. The obscurity and nature of the project have resulted in a vast number of speculatory conversions and what-if modifications. One of these gray areas is the Sturmgeschütz E 100, a short-lived plan of converting the E 100 into an assault gun. Unfortunately, there are no remaining blueprints of the layout, which has left the appearance of this vehicle up to much debate. The most well-known representation is that with a rear-mounted casemate, made famous by Wargaming’s game, World of Tanks (WoT).

Wargaming used the Sturmgeschütz to fill in their Tier X German tank destroyer line in WoT. Due to the popularity that the game enjoyed throughout the 2010s, WoT quickly became a centerpiece of information and an introduction to tanks for most amateur tank enthusiasts, making the wrongly-named Jagdpanzer E 100 what most think of when mentioning an E 100 based self-propelled gun.


WoT provides a short but somewhat inaccurate bit of historical information on the vehicle:

“The E100 was conceived as the basis for a self-propelled gun, an antiaircraft vehicle, and a tank destroyer. However, development was never started.”

There were never any plans to build an anti-aircraft vehicle based on the E 100 hull (or the Maus, for that matter). Many such designs have appeared online, but they are fake.

Likewise, there were never any plans to make an artillery self-propelled gun based on the E 100, although that fake vehicle also made it into the game in the form of the Geschützwagen E 100.

There was work made by Krupp and Porsche on an enclosed direct-firing self-propelled gun, but that particular vehicle was meant to be a Sturmgeschütz (an assault gun) and not a Jagdpanzer (tank destroyer). This was called the 15/17 cm Sturmgeschütz auf E 100 Fahrgestell (15/17 cm Assault Gun on E 100 Chassis). The project started on 9th May, 1944, when Porsche and Krupp representatives met to discuss the issue of a new heavy assault gun. Krupp showed plans for mounting either a 15 cm L/63 or a 17 cm L/53 gun inside a fixed casemate on a Maus chassis. This was in competition to what another firm, Adler, had planned, which was to mount these guns inside a fixed casemate, but on an E 100 chassis. The production quota officer, Obering Hendel, preferred the E 100 design over the Maus, as the Maus hull was significantly taller, and with a casemate mounted, would not fit through the standard railway tunnels of the time.

On 28th May 1944, it was requested that Krupp should build a 1:5th scale wooden mock-up of the E 100 chassis Sturmgeschütz, with both gun variants.

Unfortunately, the only surviving blueprints from this program is the one showing the 150 mm gun mount, leaving the position of the casemate to much debate.

The possibility that this program would have transformed into a Jagdpanzer E 100 is not at all lacking if the program would have continued. While the name is unhistorical, many German Jagdpanzers started their life as Sturmgeschütz, such as the Ferdinand, Jagdpanzer IV, Jagdpanther and Jagdtiger. The difference between a Sturmgeschütz and a Jagdpanzer was not a matter of construction or shape, but a matter of deployment and doctrine. However, the Sturmgeschütz E 100 project was terminated before the Panzerwaffe could steal it from the arms of the Sturmartillerie.

In World of Tanks

In WoT, the Jagdpanzer E 100 has a large, thickly armored superstructure at the back of the hull, in a similar fashion to that of the Ferdinand, with the engine compartment being moved towards the middle of the vehicle. The crew consists of 6 men, a commander, a driver, a gunner, a radio operator, and 2 loaders. It is armed with a 17 cm Pak, most likely inspired by the real 17 cm Stu.K. L/53 gun. It can carry 24x 170 mm rounds and reload a shell in around 25 seconds. The engine is a “Maybach Neues Projekt” with a 1,200 hp output, allowing the 134-tonne vehicle to reach a maximum speed of 30 km/h. It is crucial to note that these numbers always change in attempts by the game developers to balance the vehicle within the game environment, and are often quite far from reality, but understandable from a gaming point of view.

The Maybach Neues Projekt name is most likely fictional, but there was actually a 1,200 hp engine for the E 100. This was called the HL 234, a supercharged variant of the HL 230. It was to be coupled to an 8-speed Mekydro transmission. However, with these components, Adler moved the transmission and drive sprocket to the back, meaning that, on the E 100 tank version, the turret was moved forwards, requiring a longer hull – a very different look to the original E 100. Sadly though, Adler destroyed their plans at the end of the war to avoid capture. A rear transmission would also make it incompatible with the rear-mounted casemate possibility for the Sturmgeschütz. On the Jagdpanzer E 100, the engine has been moved to the middle of the vehicle in order to make room for the superstructure at the rear.

At the rear left on top of the superstructure, a small turret was added, with what seems like a lower caliber autocannon or heavy machine gun. Within the game, it does not operate. Such an idea is sensible for a fixed casemate vehicle its size in order to protect the vulnerable rear and left side. On the side of the casemate, small pins can be seen. These would have held up track links. The 1,100 mm wide track links would be impossible to be mounted/dismounted by hand from that position. Therefore, a small crane would be required, often shown on different models.

The tank destroyer in WoT is extremely well armored, with 250 mm at the front of the superstructure, and 150 mm towards the sides and rear. However, this, along with the heavy gun breach and ammunition, would have placed considerable strain on the rear suspension. While the real armor thickness for the Sturmgeschütz are unknown, the surviving mantlet blueprints indicate that the rounded ball mount behind the mantlet was around 120 mm thick. The thick, angled frontal plate of the casemate would be around 200 mm thick. Side and rear armor of the casemate is up to speculation, but they would likely have been rather thin (around 80 mm) to keep the weight down and eliminate stress from the rear wheels, as was done on the real E 100 turret.

In WoT, the Jagdpanzer E 100 has a 17cm PaK, inspired from the 17cm StuK L/53 gun. Krupp wanted to avoid using this gun as much as possible on the heavy Sturmgeschütz design, mainly because of its weight, but also the size of the breech and ammunition, which required a large casemate. On 29th April 1944, General Heinz Guderian requested that the penetration should be 200 mm at 4,000 meters. Essentially, this would have meant being able to knock out even the heaviest of Allied tanks from 4 km! Unfortunately, because most of the information around the 17cm L/53 is based on salvaged papers, data about its performance and shells is scarce.

Mechanical aspects

The placement of a rear casemate on the E 100 would come with a host of mechanical challenges, none of which would be possible for Germany to manage at the time. According to former Wargaming historian, Yuri Pasholok, the Combined Intelligence Objectives Sub-Committee (CIOS) claimed that the transmission and drive sprockets were moved to the rear.

Moving the engine to the middle of the tank would be a complex task, but not impossible.

The placement of a well-armored casemate so far back would have moved a great deal of weight towards the rear wheels, but due to the heavy gun and thick armor resting on the center wheels, this might have balanced out. This did have the advantage of shortening the overhang of the gun over the hull, reducing problems in narrow spaces, such as streets and forests. The Soviet SU-100, a much smaller vehicle, experienced such issues.

The heat from the engine would distort the view of the gunner and could potentially warp the gun, another issue found with many rear casemate tank destroyers.

There would be a host of mechanical changes to the E 100 hull that had to be made, increasing production time and cost. These would be adjusting transmission and drivetrain, adjusting the suspension to the different balance points, changing air intake and exhausts positions, etcetera.

This entire process had already been encountered in the Jagdtiger program. There was actually a proposal of having the Jagdtiger casemate in the rear of the hull and the engine in the middle, the Tigerjäger B, but the issues stated above, among others, led to a central casemate for the Jagdtiger to be chosen.

In recent years, model kit companies have even released models in 1:72 or 1:35 scale of the Jagdpanzer E 100, further cementing the rear-mounted casemate alternative as the most popular one.


Veteran historians and casual tank enthusiasts have been discussing this vehicle for years and we may never know for sure how a tank destroyer or assault gun based on the E 100 would have looked like. It remains one of the many fascinating and impressive projects to come out of Germany in the Second World War, alongside a similar project for the Maus and vehicles such as the Kugelpanzer. It is the simple fact that so little is known about it that allows one’s imagination to open up. The details that are known are also simply sensational, from the large gun to the heavy armor of the E 100. However, it should be remembered that, behind these impressive numbers, equally impressive mechanical and engineering problems lay, which were not solved by the Germans even for their lighter vehicles. The Sturmgeschütz E 100’s appearance in Wargaming’s video game, even under a false name, only boosted its fame within the tank community.

Panther II mit 8.8 cm KwK 43 L/71 (Fake Tank)

German Reich (1940s)
Medium Tank – Fake

During World War Two, the German war machine created some of the largest and most powerful tank designs of that time.

Nonetheless, a design that is often incorrectly cited as being one of these is the ‘Panther II mit 8.8 cm Kw.K. 43 L/71’ (Eng: Panther II with 8.8 cm Kw.K. 43 L/71). Featured prominently in popular video games such as ‘World of Tanks‘- published by Wargaming – and War Thunder – published by Gaijin, the Panther II mit 8.8 cm Kw.K. 43 L/71 has been fooling not only video gamers, but, for decades, many historians too.

The Real Panther II

The Panther II’s origins can be traced back to 1942. There were concerns that the Panther I did not have sufficient armor for protection against the anti-tank weapons that would be encountered on the Eastern Front in 1943. Of particular concern were Russian 14.5 mm anti-tank rifles, as they could penetrate the flat 40 mm lower hull sides of the Panther I at close ranges. These concerns lead to the development of a new Panther design, the Panther II, featuring a single piece 100 mm frontal plate and 60 mm side armor.

As revealed by a report from 22nd January 1943, the Panther II was originally to be identical to the Panther I except in armor and weight. Source: Jentz and Doyle.

At a meeting in Nuremberg on 10th February 1943, the chief design engineer of Maschinenfabrik Augsburg-Nürnberg (MAN), Dr. Wiebecke, stated that the current Panther design (the Panther I) did not meet specifications derived from experience on the Eastern Front. Therefore, the Panther I would be thoroughly redesigned and incorporate components from the Tiger, such as the final drives. The suspension and turret would also be redesigned and modified. This newly designed Panther was to be the Panther II. A week later, on the 17th, it was decided that the VK45.03(H) Tiger III (later redesignated as Tiger II) would become standardized along with the Panther II.

The Panther II would meet its end in May 1943, largely at the hands of 5.5 mm armored plates called ‘Schürzen’ (Eng: Skirts). Schürzen were fitted on the sides of German Panzers in order to provide protection against Soviet anti-tank rifles and these would be fitted onto the Panther I in April 1943. As Thomas Jentz and Hilary Doyle put it in their book Panther Germany’s Quest for Combat Supremacy, “the invention of Schürzen saved the Panther I. If the Panther I hadn’t been able to cope with anti-tank rifles, production would have been converted to the Panther II.”

With the fitting of Schürzen onto the Panther I, there was no longer much need for the Panther II and further development and work was largely ended. While no versuchs turm (Eng: experimental turret) for the Panther II was ever completed, a single versuchs Panther II hull was completed by MAN in Nuremberg. After the war, without access to supporting documents, when questioned if any Panther II were ever used in combat, MAN stated: Two experimental Panther 2 were ordered, although only one experimental chassis was completed. It is possible that this single experimental chassis could have been employed in combat.

As for the fate of this single versuchs Panther II hull, after the war, it was shipped to Aberdeen Proving Ground, Maryland, USA without a turret, just test weight rings. With these test weights still in place, the Panther II was sent to Detroit, Michigan, USA for testing, after which it was shipped back to Aberdeen Proving Ground where a turret from a Panther Ausf.G (Serial Number 121447) was mounted on the vehicle. The Panther II was then given to the Patton Museum in Fort Knox, Kentucky, USA. At the Patton Museum, the Panther II underwent a restoration which involved switching out the turret from Panther Ausf.G 121447 with that of Panther Ausf.G 121455. As of now, the Panther II is located at Fort Benning, Georgia, USA with the turret from Panther Ausf.G 12455.

The Real Panther mit 8.8 cm Kw.K. 43 L/71

In a meeting on 23rd January 1945, Oberst (Eng: Colonel) Holzäuer of Wa Pruef 6 reported that development of a Panther mounting the 8.8 cm Kw.K. 43 L/71 gun in a heavily modified Schmalturm was to be accomplished by Daimler Benz.

The Schmalturm (Eng: Narrow Turret) was a narrow turret design by Daimler Benz for the Panther Ausf.F designed to increase armor protection, provide a smaller target, and eliminate the shot trap of the previous curved mantlet design of the Panther.

Daimler Benz’s design called for a turret ring that was 100 mm larger than the current Panther turret ring to allow for the 8.8 cm Kw.K. 43 L/71 gun to fit. Ammunition stowage in this Panther would also decrease to 56 rounds due to the larger size of the 8.8 cm rounds as compared to the smaller 7.5 cm rounds. A wooden mock-up of the Daimler Benz design had been completed.

Krupp had previously drawn a sketch (drawing number Hln-130 dated 18th October 1944) of the 8.8 cm Kw.K. 43 L/71 gun mounted in a Panther Schmalturm with as little modifications as possible, the most notable of which was the moving of the trunnions for the 8.8 cm Kw.K. 43 L/71 gun back 350 mm, meaning the gun was moved forward 350 mm. This would allow for the 8.8 cm Kw.K. 43 L/71 gun to fit in the turret. Krupp had been awarded a contract by Wa Pruef 6 to develop this design further on 4th December 1944.

At a meeting on 20th February 1945 Wa Pruef 6, Wa Pruef 4 (a sister department to Wa Pruef 6 in charge of the development of artillery), Daimler Benz, and Krupp compared both Daimler Benz’s and Krupp’s 8.8 cm Kw.K. 43 L/71 Schmalturm proposals. It was decided that a new proposal was to be developed that featured design aspects from both Daimler Benz’s proposal, such as increasing the turret ring diameter, and Krupp’s proposal, such as relocating the trunnions. Daimler Benz was put in charge of developing the turret and Krupp was put in charge of the gun.

However, by the war’s end, all that was completed was a wooden mock-up which was still located at the Daimler Benz assembly plant in August 1945.

The Fake Panther II mit 8.8 cm Kw.K. 43 L/71

The Panther II mit 8.8 cm Kw.K. 43 L/71 was born out of a mistake made by the German tank historian, Walter J. Spielberger.

In a report on the previously mentioned 10th February 1943 meeting, it was stated how experience on the Eastern Front had shown that the Panther I did not have sufficiently thick armor. Seeing how the Panther I had yet to make its famous debut at Kursk in July 1943, Walter J. Spielberger had thought that the report was misdated and should have read 10th February 1944. Missing crucial documents that had yet to be discovered, Walter J. Spielberger then made the assumption that the Panther II project was still very much active into early 1945 despite its cancelation in May 1943. This would lead him in making the claim that the Panther II project was linked with the Panther mit 8.8 cm Kw.K. 43 L/71 project, ergo the Panther II was meant to mount the 8.8 cm Kw.K. 43 L/71 in a Schmalturm.

While there was a Panther II turret design in a Rheinmetall Borsig drawing (drawing H-Sk A 86176 dated 7th November 1943,) which showed a 7.92 mm M.G. 42 machine gun mount in a Panther II turret with a schmale blendenausführung (Eng: narrow gun mantlet model), this was completely separate from the Daimler Benz Schmalturm design for the Panther Ausf.F or the Daimler Benz Schmalturm design for the Panther mit 8.8 cm Kw.K. 43 L/71 for that matter. Also of note was that this turret design came months AFTER the cancelation of the Panther II project in May 1943.

Source: Walter J. Spielberger

The Panther II mit 8.8 cm Kw.K. 43 L/71 was essentially impossible, as the Panther II project was killed off in May 1943, whilst the earliest known drawing for a Panther fitted with an 8.8 cm Kw.K. 43 L/71 gun is Krupp’s drawing (drawing number Hln-130) which was from 18th October 1944.

The Myth Spreads

Despite correcting his mistake in the 1999 edition of his book Panther and Its Variants, Spielberger’s Panther II mit 8.8 cm Kw.K. 43 L/71 was still being touted as fact by some historians, for example, Thomas Anderson in his book Panther. The Panther II mit 8.8 cm Kw.K. 43 L/71 would further spread as a result of numerous modeling companies producing models of it, such as DRAGON, as well as its inclusion in the popular tank video games World of Tanks and War Thunder.

Note that the turret used in this iteration would not have been capable of fitting the 8.8 cm Kw.K. 43 L/71 gun as no modifications have been made to it, such as relocating the trunnions or increasing the turret ring diameter. This particular model is also fitted with German infrared devices such as the F.G. 1250 Ziel- und Kommandanten-Optik für Panther (Eng: Infrared Sight and Commander’s Scope for a Panther), a Kampfraumheizung (Eng: Crew Compartment Heater), and Schürzen, features that the real Panther II never had.

Also of note is the external travel lock fitted onto the upper glacis plate for the 8.8 cm Kw.K. 43 L/71 gun, a feature the real Panther II never had. Image:

Source:


While having parts from very real German tank designs, the Panther II mit 8.8 cm Kw.K. 43 L/71 is ultimately fake. This beast of a Panther tank was merely the result of a misunderstanding of a single sentence, not of any actual German design efforts. Despite the lack of evidence supporting its existence and its subsequent removal from further editions by Walter Spielberger, the one behind the Panther II mit 8.8 cm Kw.K. 43 L/71, the Panther II mit L/71 8.8 cm Kw.K. 43 has been propagated repeatedly in media and literature.

Also, despite repeated attempts to clear this myth, its continued presence in games such as World of Tanks and War Thunder, in certain books, and in the shape of modeling kits that present it as fact will ensure that this fake will live for years to come.

Tankenstein (Halloween Fictional Tank)

World of Tanks Blitz (2015)
Heavy Tank – Fictional

In the past year, Wargaming’s mobile version of its flagship game, ‘World of Tanks: Blitz’ has been no stranger to some less than authentic tanks. The first of this type of vehicle was actually something rather unique and original. During Halloween 2015, after completing a series of special in game missions the players could unlock the Tankenstein heavy tank. A tier VII heavy tank with premium benefits.


The World of Tanks developers came up with a made up story about the tank’s origins; in the German-esque town of Middleburg, a Doctor Tankenstein drew up plans to create a monstrous, fire breathing weapon of unequaled strength and power. Gathering parts from some of the most powerful of histories tanks, he created Tankenstein.
It draws inspiration from Mary Shelley’s 1818 novel “Frankenstein”. The name of the vehicle is also derived from that of the famous book. However, a common mistake is perpetuated, as the Frankenstein name refers to the doctor who created the ‘monster’, and not the ‘monster’ himself.

The Tankenstein as it appears in the game. Source:-
The vehicle itself is mostly an amalgamation of three vehicles. The hull is that of the Porsche’s concept for the Tiger I competition, the turret comes from one of the KV-4 variants (possibly from V. Dukhov’s design). The main armament isn’t fixed, the players being able to chose between the 105 mm T5E1 from the American T29 Heavy Tank concept or the 130mm B-13-S2 from the Soviet SU-100Y SPG prototype.
Mounting the 105mm gives the tank increased frontal turret armor as the T29’s thick mantlet is also added. The 130 mm gun is more powerful inside the game, but it lacks the above-mentioned mantlet, which lowers the vehicle’s frontal turret armor
The vehicle is adorned with abnormal features, including ventilation piping on the right of the turret, two large sickels in place of pioneering tools on the right of the hull, metal “Stitches”, a Vickers machine gun in a ball mount on the left side of the turret, spiked rivets, spiked drive and idler wheels (front left is broken), somewhat flimsy Schürzen looking side skirts cover the road wheels, and a large hot-rod style exhaust at the left rear, which emits flames when the engine is running.

More Fictional Vehicles

The Fictional tanks keep coming in Blitz. The most recent being the IS-3 ‘Defender’, and electrically powered, 3-shot Autoloader IS-3 (also designed by “Dr Tankenstein”) . The ‘Angry Connor’, an Irish version of the Archer 17-pdr, complete with large whiskey barrel.
Along with these, came the Panzer IV Anko Special and Tiger I Kuro Mori Mine tanks from the Girls und Panzer anime series. More of such vehicles were recently added to the game, in the shape of two vehicles from the Valkyria Chronicles video game series, these are the Edelweiss and Nameless Tank.

The Halloween tradition continues in 2016. This tme featuring 2 vehicles achieved in the same way as Tankenstein. This time the tanks are based of the legend of Dracula and Van Helsing, in the form of 2 unique Tier VII tanks. The T6 Dracula is a Modified AMX CDC with cape like accents, and a black paint job. The Helsing HO is a turreted Tank Destroyer featuring a Double-Barreled main gun.
Each tank has it’s own unique ammo. The Dracula has Claw (AP), Fang (APCR) and Swarm (HE). The Helsing has Stake (AP) and Belt (APCR).

Real life Tankensteins

While the Tankenstein is purely fictional and exaggerated in its construction, such ‘Cut-and-shunt’ tanks do exist in the real world. Sweden, Indonesia and most notably some middle-eastern countries have all had experimental or serving tanks of this type in their respective militaries. While there are many in existence, too many to list here, as such a select few are described below.

Nazi Germany

Infanterie PzKpfw MK II 748(e) “Oswald”
This vehicle was a mating of a captured British Matilda Mk. II with a 5cm KwK 38 gun. The turret was removed and replaced with the 5cm and its gun shield. “Oswald”, as it became known, was used as a training vehicle in the Wehrmacht.
Full article on the “Oswald” can be found HERE.


This tank was a mating of an AMX-13 turret, mounting the 75mm SA50 and the hull of a M4A4 Sherman. The vehicle was powered by the diesel engine of the M4A2. Only around 50 of these vehicles were produced. A number saw military service, taking part in action in the Sinai desert during the Six Day War of 1967.
T-100 (T-34/100)
Another modification from Egypt, this was a T-34/85 fitted with a 100 mm BS-3 anti-tank gun in a specially modified turret. The extra weight at the front of the vehicle some what affects it’s stability and makes it nose heavy. A number of these vehicles fought in the Yom Kippur War of 1973.
T-122 (T-34/122)
This is another Egyptian modified T-34. The turret has been modified in much the same way as the T-100, and the D-30 122mm howitzer has been mounted.

Republic of China/Taiwan

Type 64
The Type 64 (TL64, Chinese: 六四式), was a light tank built by mating the American M42 Duster hull with the turret of the M18 Hellcat. It mounted a 76 mm rifled gun. Its development started in Minguo 64 (1975), hence the name Type 64. Just over 50 of the vehicles were produced, the last tank rolling off the assembly line in 1979.

Soviet Union

Odessa Tank / Na Ispug
At the Siege of Odessa, 1941, the Soviet defenders came up with a plan to turn militarized tractors (namely the STZ-5) into tanks. By using naval steel borrowed from the local naval base, salvaged (and improvised) turrets, and a variety of weapons (usually machine guns), locals began producing these improvised tanks. 55-70 were made between August 20th and October 16th. These tractor tanks were able to fend off the might of the Romanian army until it was decided by the Soviets to evacuate the city.
Full article on the Odessa Tank can be found HERE.

Second Spanish Republic

Hispano Suiza MC-36 con torreta de T-26
During the Spanish Civil War (1936-1939), many vehicles were captured by the opposing side and reused. One such vehicle was a large pre-Civil War armored car designed for the police, which was flung into the furnace in the early stages of the war on the side of the Republicans. At some point, likely 1937, a Nationalist captured MC-36 was given a T-26 turret in place of its more humble Hotchkiss machine gun-armed dome turret. It served as the command vehicle for “Agrupacion de Carros del Sur“.
Full article on the Hispano Suiza MC-36 can be found HERE.


STRV M/42-57 Alt. A.2.
In an effort to up-gun their already vastly outdated Stridsvagn m/42, a meeting was held on February 15th 1952 on possible improvements. One design was to mount the French AMX-13 turret and gun on to the M/42’s hull. This idea never saw production, but the M/42 did later receive an upgraded turret and was redesignated Strv 74.

United States of America

T26E4 “Super Pershing”
This was an up-gunned M26 Pershing with salvaged Panther tank armor fixed to the bow and mantlet. Two large external recoil springs were also added to deal with the increased recoil force of the larger gun. 1 vehicle served in West Germany, early 1945.
Full article on the Super Pershing can be found HERE.

T-34(r) mit 8.8cm (Fake Tank)

Fake tanks

German Reich
Medium Tank / Self-Propelled Gun – Fake

A Captured T-34 re-armed by photoshop

Clever and deceptive photoshops are one of the best ways to invent a fake tank. There are at least three reported “T-34(r) mit 8.8cm” tanks, all in German service. The first is rather popular – a captured T-34 with a Flak 88 mounted on top – the “T-34(r) mit 8.8cm Flak“.  The second vehicle is a T-34/85 with a barrel reamed to fire 8.8cm shells – the “T-34(r) mit 8.8cm (85mm Aufgehbort)“. The third is a T-34/85 rearmed with a Tiger’s 8.8cm gun – the “T-34(r) mit 8.8cm KwK 36 L/56“. It appears as though the T-34(r) mit 8.8cm KwK 36 L/56 and the T-34(r) 8.8cm Aufgehbort were inspired by the same source – an interview with a former German tank commander. The Flak 88 version appears to have developed from a different source – a modelling magazine. Whilst the Flak version never existed, and the KwK 36 variant probably didn’t exist either, the reamed version seems slightly more plausible, although the concept is still riddled with problems.

T-34(r) mit 8.8cm Flak

This first version easily attracts the attention of modellers and tank fans alike. The idea is simple – a captured T-34 with a Flak 88 mounted on top to make an SPG. The only given history for this vehicle seems to come from Henk of Holland, a well-respected modeller. He states “This vehicle was in service with the battle group ‘Kienast’, and was used during the last battle in April 1945 in East-Sachsen [Saxony]”, although he does go on to remind us that the vehicle is fake. This battle group appears to be made up, and Henk of Holland may have obtained this information from a now-defunct internet source that cannot be traced any further.
In terms of combat, this vehicle could take on many different roles.
1. Tank Destroyer. We need only look at the well-decorated history of the Flak 88 from as early as the Spanish Civil War up until the final days of fighting in Berlin. It is almost certain that the T-34(r) mit Flak 88 would see service against the Red Army, and they knew that the T-34 and even the fearsome KV-1 could be destroyed by the Flak 88, even from long ranges. The Flak 88 was one of the most deadly and versatile artillery pieces of its time. For AT duties, its accuracy and power were realistically only matched by the Firefly’s 17-pounder gun and the Soviet 100mm BS-3 M1944 gun in the late war. The Flak 88 had a staggering effective range of just under 15,000 meters! It would simply be out of range of most enemy guns, whilst it could easily fire upon them. Apart from which, it was even given a telescopic sight for engaging ground targets, which meant that direct long range fire was done with ease.
In the Battle of France, the Flak 88 managed to destroy 152 tanks, including the Matilda II and Char B1, which the 3.7cm AT guns could not. By mounting the Flak 88 on a captured chassis, the users would have had a superb Tank Destroyer, because it would be able to quickly relocate (owing to the T-34’s rugged and reliable chassis), but deliver a knock-out blow with each shot. The Flak 88 was actually the basis for the universally-feared 8.8cm KwK 36 gun as mounted on the Tiger! The Flak 88 also had a more than agreeable gun elevation: -3 to 85 degrees, which would allow it to adopt many different firing positions, not dictated by the evenness of the ground. However, it must be noted that the Flak 88 even not mounted on a vehicle was often too tall to be camouflaged effectively, now atop a T-34 chassis, the vehicle would be approximately 18 feet tall giving it a huge profile – to put this into perspective, the Tiger was only 9 feet 10 inches tall.
2. Bunker destroyer. The Flak 88 saw prolific use mounted on vehicles at the Battle of France, with the Sd.Kfz.8 heavy tractor – the “Bunkerknacker”. Throughout the battle, the Flak 88 reportedly destroyed 151 bunkers, thus meaning that perhaps the T-34(r) mit Flak 88 could do the same job. However, the lack of protection for the crew would be problematic and could lead to casualties. Also, the T-34’s hull would not be able to take heavy punishment if it were to come up against an AT gun or any other tank that the USSR could field (excluding some lighter vehicles) at close quarters. Therefore, it may not be best suited to this role, but could certainly do so if needs be.
3. SPAAG. The Flak 88, whilst possibly better known for its anti-tank role, was originally an anti-aircraft gun. It was only turned on tanks when the 3.7cm guns were found unsatisfactory at engaging certain heavily armored tanks. However, overall it may not be worthwhile using the vehicle as a SPAAG, as the Flak 88 had a rather limited firing ceiling of just under 8000m, which meant that many aircraft could fly above this range. Seeing as though it would likely only fight against Soviet aircraft, it would be able to engage the most produced aircraft that the USSR had – the IL-2 with its maximum service ceiling of 5500m, although the Yak-9 (the second most numerous Soviet aircraft during the war) had a maximum service ceiling of 9100m, which would put it out of range in theory, although they often operated below this. Having said this, the effectiveness of anti-aircraft guns can, and was, called into question during the war, and it may not be worth using the vehicle for this role.
General problems with this vehicle would be apparent. Firstly, the gun arc would be problematic. The fact is that the T-34 chassis would not necessarily be wide enough to allow the crew manning the Flak 88 to turn the gun too far to one side, unless they welded on a platform on which to stand and operate the gun from. Standing on the T-34’s sloped sides would be a dangerous and tricky affair when handling artillery shells. The Flak 88 is a little under 8 ft (excluding the barrel), and the T-34’s chassis is only 9ft, so there would be little space for the crew to operate the gun in.
Secondly, there would also be little space to stow munitions. As seen on a scale model, it would be likely that munitions would be stowed on deck, but this can be dangerous, as they could be hit and would explode directly next to or on top of the engine compartment. It is also important to note that by doing this, there would be no space for external fuel tanks, thus significantly reducing the range of the vehicle.
Thirdly, the crew would be vulnerable to small arms fire. Despite a large gunshield on front, as with any open-cabin vehicle, enemy snipers or heavy machine guns (such as the DShK) would have little trouble making quick work of the crew, thus rendering the vehicle near useless. This is actually very important because the crew being killed by simple small arms fire is a significant risk to the overall capabilities of the vehicle, and therefore its usefulness as a viable weapon come in to question. For example, many loaders of the American M58 Ontos were killed by enemy small arms fire when reloading the external recoiless rifles. Similarly, crews of the SU-76 were incredibly vulnerable in urban combat, so good teamwork with infantry to support the tank was needed to avoid crew casualties.
Finally, the Flak 88 actually weighs roughly 1.4 tons less than a common early model T-34/85 turret (with an S-53 gun), but this weight would be heavily concentrated near the front of the vehicle, making it very nose heavy. This could stress the chassis in one particular area of the vehicle instead of giving more even distribution as with a turret. Also, top speed might be slightly lower as a result of the wind resistance from the enormous flat gunshield, but the lowered weight might roughly compensate for this. However, the bigger problem would be the center of mass being raised on the vehicle. The Flak 88 was normally fired from a secure and wide ground mount, thus the vehicle might be prone to toppling into ditches, or wobbling when firing as a result of the recoil, thus impairing aiming. This could be particularly dangerous to the crew if engaging multiple targets which are within range of returning fire, meaning that the effective rounds per minute is decreased.
Overall, the T-34(r) mit 8.8cm Flak would be comparable to the Nashorn (Sd.Kfz.164), with its 8.8cm Pak 43/1 (a gun designed by Krupp in competition with the Flak 41), generally similar construction, and similar likely roles. Of course, the Nashorn would have had one major advantage over the T-34(r) mit 8.8cm Flak, which is that it had all around protection for its crew, except for the roof. The Nashorn had a very high profile – 8ft 8in, but the T-34(r) mit 8.8cm Flak would be, as mentioned, 18 ft tall, meaning that the vehicle would be incredibly conspicuous. In fact, Nashorn production was cancelled in favor of the Jagdpanzer IV because it had a lower profile and thicker frontal armor, even despite having a less potent 7.5cm gun, so it is clear that unlike the USSR, which favored mounting the biggest guns available, Germany would favor vehicles which can be used for ambush attacks, as part of their overall defensive campaign during the late war.


This fake tank came about as a result of a single photoshop showing a T-34 chassis mounting a Flak 88 instead of a turret. This is actually a very plausible vehicle on numerous levels. Firstly, the Germans did mount Flak 88s on their own vehicles – such as on Panzer IVs, or on prime movers, such as the Sd.Kfz.8, in large numbers. Secondly, the Germans were known to mount weapons on captured vehicles in a similar manner – for example, some captured T-20 Komsomolets were modified to carry a 3.7cm Pak 35/36, a concept as seen first with the Soviet ZiS-30. Finally, after WWII, a lot of countries that used the T-34 made similar modifications – for example, the Cubans mounted a 122mm gun on a T-34/85, after cutting away some of the turret, the Syrians mounted a 122mm on a T-34 chassis by reversing the hull, and the Egyptians even made a new superstructure to fit a 122mm gun, these three designs thus showing that a modification of a T-34 into a self-propelled gun was more than possible.
However, one thing must be noted about the D-30 122mm gun – it weighed less than half of the Flak 88, in fact, it was a staggering 4.6 tons less! Whilst the D-30 was 34mm larger than the Flak 88, it was also 18 calibers smaller, and apart from which, it was a much simpler gun. Weight is particularly important when considering possible modifications to the T-34 chassis, as whilst it was a very rugged chassis, it had its limits, and such SPG modifications of the T-34 are perhaps the most the chassis could bare. Similar to the Flak 88 as mounted on a Panzer IV, the chassis would be seriously lowered as a result of the excess weight, and this is evident in photographs. Having said this, the T-34 had a weight load of 15 tons more than the Panzer IV, which might accommodate the Flak 88 with more ease.
According to Network54 forum, the photopshopped image of the T-34(r) mit 8.8cm Flak seems to have first appeared in around 2007 in a Japanese modelling magazine – “Armour Modelling“, along with a number of other ‘what-if’ models. One user, Hisato Shinohara (who claims to have even been asked to make the image for the magazine) remarked that: “We only wanted to see what sort of things we can come up with. Please look at them as an alternative way to ‘just to enjoy and be playful’. We did say that they are all fake at the end. However, come to think of it, that it was not written in English and I can see that it can be a big problem! The intention was to surprise the readers for a moment, and for this reason, it was clearly stated that they were all fake right at the beginning.
Since then, it has circulated prolifically across the internet. Often, this vehicle appears on World of Tanks and Warthunder forums, which almost certainly contributed to its popularity. In fact, since the creation of the “waffentrager research line” on World of Tanks, its popularity probably increased even more with fans demanding the companies make this tank in the game. In the last few years, the original photo of the T-34 used for the photoshop has been found and is commonly posted following any mention of the T-34(r) mit Flak 88.

T-34(r) mit 8.8cm (85mm Aufgebohrt)

The second and third version of the T-34(r) mit 8.8cm appear to be related. This version of this T-34(r) mit 8,8cm was a simple T-34/85 with a gun reamed to 8.8cm from 85mm (probably an S-53 as the D-5T saw limited production).
According to an interview with Wolfgang Kloth (a German tank commander during the war) at the 2008 AMPS (armor modelling and preservation society) international show, he discusses a Panzerbrigade in Courland, Latvia (spelled Kurland by the Germans):
There was an interesting unit in Kurland; Panzerbrigade Kurland, and they only had captured tanks. They had a Sherman and a General Lee and two T-34s. They took Russian 87mm, and took it to the ship wharf, and reamed it to 88. They shot 88 ammunition out of it. They were very inventive! Because up in Kurland, your back was against the water, you know.
The suggestion of re-boring the barrel to fire 88mm shells sounds dubious. It would be wrong to dismiss Kloth’s story based on the fact that he suggests the Soviets had 87mm guns. He did serve at Kurland, lending some credibility to the story – In 1944, he was transferred to the surrounding areas of Kurland with a Panzerjager unit until May 1945. He is the only source for this story, and this makes it hard to definitively say whether or not this story is true.
The only other way to determine whether or not this is true is to consider ballistics. There is a long standing debate on whether or not captured shells of similar or the same caliber can be fired by tanks. It is possible that the S-53 barrel could be rebored to 88mm, assuming that any ships at Courland had the right equipment, as stated in Kloth’s story. However, it is unclear whether or not the Pz.Gr. 39 shell would work in the breech of the modified S-53 gun. There is no firing chamber like with rifles in tank guns. Assuming that the casing of the shell fitted inside such a modified gun, it is possible that it would fire. However, the length and diameter of the shell case, powder charge, and tapering of the neck and shell case might need to match, too. If the shell has too much powder charge, the shell might misfire to varying degrees – It might fire inaccurately, it might blow the breech block apart and damage the gun mechanism. Finally, the ammunition used for the KwK 36 was electrically primed. Normally, shells of higher calibers have a self-contained primer which is ignited using a percussion cap – this is very different to the KwK 36 gun. This single fact means that the reaming of the S-53 gun might not have been enough to make the shells fire. It would require a drastic reworking of the gun with very complex mechanisms. For these reasons, it is almost certain that this vehicle is also a myth.

T-34(r) mit 8.8cm KwK 36 L/56

The final purported vehicle is a T-34/85 sporting an 8,8cm gun of a Tiger. This is rather unlikely. The original source for this vehicle is difficult to track down, but it appears to have come from (although the page for this vehicle on that website does not appear to exist). This website is referenced on, which talks about unconfirmed and hypothetical conversions. states (the following extract has been edited to make grammatical sense):
In July / August, 1944, at the shipyard in Libau [in Latvia, now known as Liepaja], an 8,8cm gun from a damaged Tiger I was mounted [onto a T-34/85]. From the end of 1944, this tank was used by the 12th Panzerdivision in Kurland [possibly referring to Heeresgruppe Kurland]. The tank’s color was kept the same, dark green [the source is not clear whether this is Soviet tank green, or a German green color], and a large cross was drawn on the turret for identification. The [identification number] was supposedly ’18’. The tank was [later] given the identification mark ’12’, and was given the Kurland sign [identification markings]. The crew drew eight white tanks on the barrel and wrote ‘Hi Kommet’ on it, too. However, this conversion is highly improbable.
Other sources explicitly refer to additional modifications such as a Tiger’s exterior ammo box, although did draw one on their illustration. The vehicle even appears to have made it into the World of Tanks Xbox game under the designation “T-34-88“, with the “Historical Information” stating: “For the armies of WWII, pressing captured vehicles into service was fairly commonplace. There were unconfirmed reports of a German unit refitting a captured T-34-85 with an 88mm gun. Allegedly this tank saw fighting with the 7th Panzer Division in East Prussia. Hence the concept for the T-34-88 was born.


The T-34/85 turret is hardly a likely candidate for holding such a long, heavy gun. It would probably cause the suspension serious problems – it is widely known that the attempts by the Soviet to fit a 100mm gun to the T-34/85 caused the suspension to buckle and break during firing. Secondly, there would have to be extensive and incredibly precise engineering in order to actually fit the huge gun in the T-34’s gun mount (and being able to give it any elevation or depression), something probably not available to any units outside of heavy factories of Germany. Thirdly, the gun itself was huge and complicated. In fact, the KwK 36 L/56 took up most of the internal space for the Tiger I turret. It is extremely unlikely that there would be internal space in a T-34/85 turret in which to accommodate such a large gun.
Fitting a new parts to captured Soviet tanks is not uncommon. For example, many early war tanks such as the KV-1, KV-2, and early model T-34s received new commander’s cupolas and headlights. However, fitting a new gun is somewhat more rare. It is known that a 75mm KwK 40 was fitted to a KV-1 and saw action at Kursk, but this seems to be a very rare occurrence, probably owing to the difficulty of the task. This may have inspired this monster T-34 in part.
Overall, the vehicle appears to have been inspired by the reamed T-34 that Kloth mentions in his interview. Although he explicitly states that the gun was reamed (that is, rebored), it is obvious that both of the vehicles have the same story, and it is likely that an internet source either misinterpreted the interview, or used it as inspiration for a fantasy vehicle.

T-34/85 Beutepanzer
A typical T-34(r) Beutepanzer. From the outside, it would be impossible to tell if the gun has been reamed to fire 8.8cm shells.
T-34 mit 88mm
A photoshopped image of a T-34(r) mit 8,8cm Flak 88. This is a highly convincing image, and the only immediate giveaway for it being a fake is the fact that the chassis appears remarkably unstressed. Notice how tall the vehicle is compared to the soldiers. It would have a tall profile, making it very difficult to camouflage, and its relatively thin armor (80mm hull, and mere gunshield) would mean that if it were targeted by enemy AT guns, it would most likely be destroyed. This is unlike the KV-2, which, whilst it was a very tall tank, it had the armor to cope with the attention it received. T-34 original mit 88
The unphotoshopped T-34/85 before it was given an 8.8cm Flak. From this, we can deduce that the photoshoped image has been shortened, and the soldiers have been somewhat edited. The gun with the muzzle brake on the right has also been mysteriously edited out in the fake image for seemingly no reason. The markings on this vehicle are also unknown, and do not appear on the photoshopped image.T-34 mit 88 drawing
A drawing of the T-34(r) mit 8.8cm Flak. The Flak 88 in this drawing appears rather low, and it is possible that the artist has neglected how the gun actually works. Certain controls, such as the elevation crank would be difficult to operate by the crew, given this layout.Henk of Holland T-34 mit 88 flak
A model of the T-34(r) mit 8.8cm Flak by Henk of Holland. Similar to the above drawing, the Flak 88 in this model appears too low, and the crew would have to crouch down to operate certain controls. There also appears to be no space in which to carry munitions, and it is likely that it would need to tow a limber carrying munitions.
Henk of Holland T-34 mit 88 flak not his own
Another more detailed model of the T-34(r) mit 8.8cm Flak. It is likely that ammo would be stowed on deck, if this vehicle were real. Notice how the munitions are stacked right next to the engine compartment. If hit, the munitions might explode, thus causing a catastrophe for the vehicle and its crew.
komsomolets w 3.7cm pak mounted
A knocked out beutepanzer Komsomolets featuring a 3.7cm Pak AT gun. This is a rare modification of the Komsomolets, and it is unclear how many were modified in this manner. They appear similar in design to the ZiS-30, which featured a large gunshield, too. However, this vehicle would be more stable than the ZiS-30, as the gun was not nearly as big. Perhaps this modification helped inspire the T-34(r) mit Flak 8.8cm.
sdkfz 8 flak
An Sd.Kfz.8 with a Flak 88. Notice how the Flak 88 is significantly taller than the ones seen on the models and drawings of the T-34(r). It weighed 22 tons, but had very limited armor – only 14.5mm at most. It was 24.1 foot long, 9.2 feet tall, and 8.7 feet wide. The gunshield limited traverse of the turret to 151 degrees either side. Only ten were made and three were lost by March 1943. These vehicles first saw action in Poland, 1939, but it was in the Battle of France, 1940, in which it performed both anti-bunker and AT duties. They excelled at both, being able to destroy even the heaviest tanks that the Allies could send at them – the Matilda and Char B1. Notice that there is rather limited space for the crew to operate on the deck, and the vehicle itself is huge, making it rather conspicuous.
T-100 Egypt
An Egyptian T-34 with a 100mm BS-3 mounted in a new superstructure. There was also reportedly a D-30 howitzer version featuring a very similar superstructure. The Egyptians were particularly inventive with their design, given that they were the only ones who modified the D-30 gun mounted inside an enclosed superstructure (notably larger than the T-34/85 turret). Enclosed superstructures can be cramped, and create significant weight problems – this T-100 (Egyptian designation) at Yad La-Shiryon Museum, Israel, is almost certainly dangerously nose heavy, and the chassis appears very low. This turret and gun still probably weigh less than the Flak 88, and still they stress the chassis.
cuban t-34 d30
A Cuban T-34 with a 120mm D-30 gun mounted in a cutaway T-34/85. This modification proves that mounting a large gun on the T-34 is possible, but the BS-3 weighed less than half of the Flak 88 (in fact, roughly 4.1 tons less). The BS-3 and D-30 guns were widely exported by the USSR, and are a very common sight in armies, even today! By cutting away the turret, more space is given for the crew, and there is less weight and thus vehicle has less stress on the suspension.
Syrian t-34 d30
A Syrian modification of the T-34 to fit a 122mm D-30. Notice that they reversed the hull and fitted the gun on to the rear in order to avoid difficulty in creating a new turret or superstructure in which to house the gun. This means that the vehicle can maintain a very low profile, avoid weight problems and thus keep its maneuverability.
A scale model of a T-34 with a Tiger’s 88mm gun and ammo basket mounted on it. This is one of many scale models as seen on the internet. This one shows it to feature a more common German green color, despite other sources referring to other colors.
KV-1 kwk 40
A KV-1 with a KwK 40 gun as seen at Kursk. Conversions of guns onto captured vehicles appears to have been rare, this being the only known photograph of the modified KV-1. The monumental task of mounting a German gun onto a Soviet tank would be staggering, but it is more than possible.
