Unlike earlier self-propelled anti-aircraft guns, it had a fully enclosed, rotating turret.
The MK 103 had also been fitted in single mounts to such planes as the Henschel Hs 129 in a ventral gun pod, and to the twin-engined Dornier Do 335.
The Kugelblitz combined the chassis and basic superstructure of the Panzer IV tank with a newly designed oscillating turret.
Mass production was planned, but never happened due to the disruption by Allied bombing efforts.
[4] Today, one complete Kugelblitz turret is exhibited at the Lehrsammlung der Heeresflugabwehrschule (collection of the German army anti-aircraft school), Rendsburg.
