The Flakpanzer IV "Wirbelwind" (Whirlwind in English) was a self-propelled anti-aircraft gun based on the Panzer IV tank. It was developed in 1944 as a successor to the earlier self-propelled anti-aircraft gun Möbelwagen.

In the first years of the war, the Wehrmacht had less interest in developing self-propelled anti-aircraft guns, but as the Allies began to gain air superiority, the need for more mobile and better-armed self-propelled anti-aircraft guns increased. During the early summer of 1944, SS-Hauptsturmführer Karl Wilhelm Krause with the 12th SS Panzer Division Hitlerjugend came up with the concept of the Flakpanzer IV Wirbelwind.[1] He presented the concept to SS-Obersturmbannführer Max Wünsche, commanding officer of the 12th SS Panzer Regiment and it was approved by Hitler.

The Panzer IV's turret was removed and replaced with an open-top, nine-sided turret which housed a quadruple 2 cm Flakvierling 38 L/112.5. A closed-top design would have been preferable, but this was not possible due to the heavy smoke generated by the four anti-aircraft guns. Production of the tank was carried out by Ostbau Werke in Sagan, Silesia. Thereafter, the 2 cm shells proved less effective against aircraft so a more powerful successor was produced which eventually replaced it. Known as the Flakpanzer IV Ostwind (East Wind), the successor was equipped with a single 3.7 cm FlaK 43.[2][3]

The combination of armor and rapid fire from the four guns of the Wirbelwind did make it effective against ground targets.[4]

Between 87 and 105 Wirbelwinds were produced during the war, but due to discrepancies between the recorded production numbers at the Ostbau Works and Wehrmacht service records, the exact number will probably never be known.[5][6]
