Ostwind


The Flakpanzer IV "Ostwind" was a German self-propelled anti-aircraft gun based on the Panzer IV tank. It was developed in 1944 as a successor to the earlier Flakpanzer IV/2 cm Vierling Wirbelwind.
The Panzer IV's turret was removed and replaced with an open-top, hexagonal turret that housed a 3.7 cm FlaK 43. In addition to its intended role as an anti-aircraft weapon, the fast-firing gun was highly effective against light vehicles and minor fortifications. A closed-top design would have been preferable, but this was not possible due to the heavy smoke generated by the gun.
The Ostwind's main improvement over the Wirbelwind was the FlaK 43's increased range and stopping power over the 2 cm Flakvierling 38 and slightly better armor on its turret.
Although an order for 100 vehicles was placed in August 1944, only 44 vehicles were completed from December 1944 to March 1945, all work being carried out by Ostbau Werke in Sagan, Silesia.
