Comparing: VK 30.01 (D) vs. VK 30.01 (P)

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.

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.
