WW2 German SPAAGs

Flakpanzer I

Nazi Germany (1941) SPAAG – 24 built

The first German dedicated SPAAG

Although most armored vehicles in service had some AA capabilities thanks to articulated pintle arms and the rapid-fire of the MG 34, half-tracks carrying 20 (0.79 in) and 37 mm (1.46 in) guns were envisioned at first in order to support the mobile Panzer Divisions. However, tanks chassis soon started being used for this role. Although the Luftwaffe had overall superiority in France in 1940, the need for a mobile, well protected anti-aircraft vehicle that could follow the Panzerdivisions was recognized. The 2 cm Flak 38 auf Panzer I Ausführung A was planned by the Heereswaffenamt in 1941 and conversions begun at the Stoewer company on obsolete Panzer I Ausf.A chassis.

Design of the Flakpanzer I

Stoewer was not content with just erasing the superstructure. To improve stability, the frontal part of the superstructure was kept, but moved 20 cm (7.9 in) forward, and the engine deck cover was modified in order to increase the usable area when using the gun. On both sides, flaps made of sheet metal did not provide any protection, but created a platform when lowered, which again increased available space. In order to store extra ammunition, the original emitter/receiver radio was disposed of. Only the driver was offered some protection. Ammunition was stored under his seat and behind the loader. The 2 cm FlaK 38 L/112.5 was installed slightly offset to the right. This quick-firing autocannon was protected by a shield.
This piece of ordinance was produced by Rheinmetall-Borsig and Mauser until the end of the war, with some 144,000 units being delivered by the end. It weighed about 450 kg (992 lbs), was served by a normal crew of 7 (reduced to 5 in thid case), had a 360° traverse, -12° to ±90° elevation, 120-180 or 280–450 rpm (cyclic/practical), and 2200 m (2200 yd) maximal range for a muzzle velocity of about 900 m/s (3000 ft/s). Other than that, the crew relied on personal weaponry for close defense. Importantly, the vehicle was modified to tow a Sonderanhänger 51 trailer, which could house the extra ammo and spare barrels, while the crew usually followed in trucks or half-tracks.

The Flakpanzer I in action

Due to the small number of conversions, only the Flak Abteilung (mot) 614 was fully equipped in 1941 and stationed in Romania. It later departed to the southern front. The puny gun was of little use against fast-flying aircraft, but was found quite useful for infantry support, due to its high rate of fire and extreme accuracy. However, the lack of protection meant high casualties in operations, so the vehicles were reallocated to quieter sectors. Some took part in the AA defense of the Stalingrad sector, but the surviving vehicles were all wiped out during the great counter-offensive of 1943.

Hey there! Thanks for covering so many tanks in detail.
It would be very nice if you could cover the rest of the Flakpanzer.
– Flakpanzer 38(t) “Gepard” – Sd.Kfz. 140
– Flakpanzer IV “Möbelwagen” (Sd.Kfz. 161/3)
– Flakpanzer IV “Wirbelwind” (Sd.Kfz. 161/4)
– Flakpanzer IV “Ostwind”
– Flakpanzer IV Kugelblitz (Prototype)

Interesting article on a fascinating piece of ordinance. I love these Pz.I concessions!
But you state that “with some 144,000 units being delivered by the end”, yet “the small number of conversions” and the total production was “24”.
Some clarification would be helpful.

Because they’re re-purposed tank chassis, perhaps? The natural lineage of the Panzer I should include the Flakpanzer I.

I find it kind of amusing that a weapon such as this could be pounding away at the sky and suddenly find itself squared off against enemy armor. Especially so on the Russian Front. I imagine suddenly looking down from my mount and find myself eye to eye with a BT-7 or an early production T-34. This is an awesome site. One of the best armor sites on the web. Kudos guys.

I like tank encyclopedia David i am italian modeler i use this encyclopedia for my tanks. i like the pictures and story of tanks.
