The Black Knight is a prototype unmanned ground combat vehicle designed by BAE Systems. It weighs approximately 12 tons and is deployable from a C-130; thus, the Black Knight can be airlifted by military transport aircraft. Similar in appearance to a tank, it is armed with a turret-mounted 30 mm gun and a 7.62 mm coaxial machine gun. The vehicle is fitted with a 300-horsepower Caterpillar Corporation diesel engine. The vehicle is currently being evaluated by the US Army. It is a proof of concept for military unmanned vehicles, specifically as a combat asset.
