Flakpanzer Gepard

The Flugabwehrkanonenpanzer Gepard "Anti-aircraft cannon tank Cheetah", better known as the Flakpanzer Gepard or Gepard 1, is an autonomous, all-weather-capable German self-propelled anti-aircraft gun (SPAAG). It was developed in the 1960s and fielded in the 1970s, and has been upgraded several times with the latest electronics. It constituted a cornerstone of the air defence of the German Army (Bundeswehr) and a number of other NATO countries. In Germany, the Gepard was phased out in late 2010.

The vehicle is based on the hull of Leopard 1 tank with a large fully rotating turret carrying the armament—a pair of 35 mm Oerlikon KDA autocannons and the two radar dishes—a general search radar at the rear of the turret and the tracking radar, and a laser rangefinder, at the front between the guns. Each gun has a firing rate of 550 rounds/min.
