In 1970, Krupp GmbH investigated the possibility of creating a vehicle with a crew of one to three members, or even a remote-controlled tank without a crew. The basic prototype was supposed to feature an adjustable hydropneumatic suspension with very long rollers' travel and high specific power. The main armament was a gun with two-plane stabilization. Using a lifting roof over the gun breech provided a depression angle of -10 degrees. The crew was located in the rear and controlled the vehicle using cameras and highly-automated remote systems. The vehicle's excellent mobility was intended to be its main form of protection. Work on the project was discontinued at the modeling and blueprint stage.
