with a capacity of 20 kVA for the ventilation, fire-control and radar systems, and a 300 A 28 volt direct current generator for the electrical system. The fuel capacity is 985 liters, which ensures a combined operating time of approximately 48 hours. The chassis and the track were taken directly from the Leopard 1. It has torsion bar spring-mounted roadwheels with seven roadwheel pairs per side. They are connected to the torsion bars on swing arms, whose deflection is limited by volute springs. Drive is through the drive sprockets located at the rear. The rubber-mounted shocks were modified to achieve better stability during firing. The track is manufactured by the company Diehl, rubber track pads fitted, and is "live" track with rubber bushings between the track links and pins (type: D 640 A). Grouser/icecleats can replace the rubber pads on some track links to increase traction on slippery surfaces. The hull only had slight modifications, i.e. a modified roadwheel distance (8 cm increased distance between the third and fourth roadwheel) and the transfer of additional batteries in battery boxes at the rear. The batteries and the electrical system operate at 24 volts DC. Turret 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 that is placed in the front of the hull to the left of the driver. It also powers the radars and the fire-finding system. Radar and laser The Gepard has two radar dishes: a general search radar at the rear of the turret and a tracking radar at the front between the guns. Some are equipped with a laser rangefinder on top of the tracking radar. Guns The guns are 90 calibres () long, with a muzzle velocity of (FAPDS (Frangible Armour Piercing Discarding Sabot) rounds), giving an effective range of . The ammunition is 35×228mm calibre (STANAG 4516). The KDA autocannon has a dual belt feed for two different ammunition types; the usual loading per gun is 320 AA rounds fed from inside the turret and 20 AP rounds fed from a small outlying storage. Each gun has a firing rate of 550 rounds/min. The combined rate of fire is 1,100 rounds/min, which – in unlimited mode – gives a continuous fire time of 35 seconds before running out of ammunition (with 640 AA rounds for both guns). It is standard to fire
