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.
Characteristics are specified for a vehicle with crew members trained to 100%.
