It was powered by a water-cooled Maybach HL 120 TR engine and it had a top speed of about 38.6 km/h (24 mph). The weight of the Wirbelwind was about 21,772 kg and the length was 5.92m. It had a 6 speed forward, 1 speed reverse transmission and it was also capable of storing up to about 3,200 rounds for the main AA guns. The armor varied between 7.6 cm in the front to 2.5 cm in the sides.The Wirbelwind had no other variants besides the main production model. However, there was an attempt to put the Wirbelwind turret or the Ostwind turret on a Panzer III body, but the war ended in Europe before this could happen.
The Flakpanzer IV Wirbelwind's first prototype appeared in 1944 and mainly all Wirbelwinds were then assaigned to Flugabwehrzüge units which were meant to be Anti-Aircraft. By the time WWII ended in Europe, around 105-110 Wirbelwinds had been produced. They were produced by Ostbau and in 1945 Soviet troops forced the Ostbau factory to move from Silesia to Teplitz which is northwest of Berlin.
