The Ostwind was a German anti-aircraft tank
designed during World War II
. It consisted of a 37mm Flak 43 gun
mounted in a hexagonal armor
ed turret on the chassis of a PzKpfw IV. The turret
was open-topped but intended to give the crew
better protection from ground fire
than previous self-propelled anti-aircraft units.
Developed late in 1943, few were produced due to growing resource shortages in the German economy. This was unfortunate for the AAA crews of the Wehrmacht at the time, as the Ostwind was quite a bit more effective than the other weapons available at the time.
