Starting in 1938, the VK 20 series were the proposed replacements of the Panzer IV and Panzer III tanks with entries by MAN, Krupp and Daimler Benz. It was initially projected to weigh 20 tonnes but grew to 24 tonnes. By November 1941, the designs almost reached completion but against the professional judgement of Wa Pruef 6, political interference on December 1941 lead to all of the designs being dropped.
