The Flugabwehrkanonenpanzer Gepard is an 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 and replaced by Wiesel 2 Ozelot Leichtes Flugabwehrsystem (LeFlaSys) with four FIM-92 Stinger or LFK NG missile launchers. A variant with the MANTIS gun system and LFK NG missiles, based on the GTK Boxer, was also considered.
The vehicle is based on the hull of the 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. The guns are 90 calibres long, with a muzzle velocity of 1,440 m/s, giving an effective range of 5,500 m. The KDA autocannon can take two different ammunition types; the usual loading is a mix of 320 AA and 20 AP rounds per gun. Combined rate of fire is 1,100 rounds/min. The electrically driven turret is powered by a 40 kW generator driven by a 4-cylinder, 3.8 litre Mercedes-Benz OM 314 multi-fuel engine.
