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

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.

In the winter of 1941–1942 the WaPrüf 6 issued technical requirements for a new 30-ton tank. The orders for development were placed with MAN and Daimler-Benz. The prototypes were to be ready by May 1942. However, on May 13th, 1942 only comparative characteristics of the projects were submitted. The MAN's project was preferred, and the Daimler-Benz's project was canceled.
