Ostwind paired the Panzer IV chassis with a rotating open turret and a single 37 mm Flak 43, trading Wirbelwind’s volume of fire for greater range and hitting power.

Development and design
Ostwind developed from the same Panzer IV Flakpanzer program as Wirbelwind but mounted a 37 mm Flak 43 in a larger open turret. The heavier gun answered criticism that 20 mm weapons were losing effectiveness against fast, robust aircraft. 1, 2
Operational use
Only limited numbers were completed before Germany’s collapse. The type nonetheless represented a more balanced mobile gun-defense concept, combining immediate turreted reaction with a harder-hitting weapon. 1, 2
Role and significance
Ostwind illustrates the late-war shift from sheer rate of fire toward larger-caliber automatic cannon with greater engagement reach. 1, 2
