Comparing: VK 30.01 (P) vs. AC 4 Experimental

The Porsche company developed the concept of a new vehicle in 1939. On March 5, 1941, after numerous approvals, the company prepared blueprints and, in July 1941, produced the hull from mild steel. The hull and chassis (with detachable equipment for trenching) passed performance trials. One wooden prototype of the turret and one wooden prototype of the hull were manufactured. In 1942, the project was discontinued in favor of new heavy tanks.

The tank was developed in 1943. An order was placed for 400 vehicles. The prototype was created on the basis of the AC 1 tank with an enlarged superstructure, which allowed mounting a modified turret from the AC 3 tank with a 17-pounder gun. In July 1943, the work on the project was stopped at the final stage, as the program for creating the Australian cruiser tank was discontinued.
