The Flakpanzer IV "Ostwind" (East Wind in English) 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 and produced at the Ostbau Works plant.
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. While a closed-top design was preferred, this was precluded by the amount of smoke generated by the gun.
