History and Performance
In November of 1944, the German armament giant Krupp proposed conceptual designs that would increase the armament of all Jagdpanzers and panzers currently in production. The idea behind the proposal was to permit the German vehicles to engage the enemy with the most effective armament with the minimum amount of protective armor. The E-75 "Standard panzer" was to be a heavy tank to replace the PzKpfW VIB Tiger II. The new vehicle would be armed with the 10.f cm KwK (L/68). This gun would have most likely required the redesign of the turret. The rate of fire would be reduced with the use of two-part munitions, and a second crew loader would be required, adding space for the additional crew. This vehicle never proceeded beyond the design proposal.
