Comparing: VK 100.01 (P) vs. IS-3A

A version of the Maus from June 4, 1942. The 120-ton predecessor of the superheavy tank existed only in blueprints and never saw service. The vehicle was only an intermittent stage in the development of the Maus.

In 1956–1957, the Military Armored Forces Academy developed a speculative design for a new loading system on the IS-3 and T-10 heavy tanks. The IS-3 variant featured a double-row ammo rack with an automatic loading system. The crew was reduced to three members: commander, gunner, and driver. The turret was redesigned in order to accommodate the loading mechanism. The vehicle existed only in blueprints.
