A missile tank is an armoured fighting vehicle fulfilling the role of a main battle tank, but using only guided missiles for main armament. Several nations have experimented with prototypes, notably the Soviet Union during the tenure of Nikita Khrushchev (projects Obyekt 167, Obyekt 137Ml, Obyekt 155Ml), But only the West German Jaguar 1 Rakete saw service as a standard vehicle, although the Soviet IT-1 missile tank also saw limited service.
