3.7cm Flak 43 Flakpanzer IV Ostwind The Ostwind ("East Wind") was a self-propelled anti-aircraft system based on the chassis of the Panzer IV tank. The main armament was a 3.7cm FlaK 43/1 cannon mounted in a six-sided open-topped turret that could traverse 360. An order for 100 such vehicles was placed in August 1944, with such vehicles being necessary to counter enemy aircraft that freely roved the skies due to Allied air superiority.
