In November 1944 the Krupp company presented several avant-projects aimed to upgrade armament of tanks and tank destroyers in service. Among them there was a project of mounting a Panther's Schmalturm (tight turret) on the Pz IV Ausf. J. The project was canceled due to phasing out the Pz IV production.

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.
