Comparing: 112 vs. IS-3A

The development of the 112 tank started in 1962. The project was to feature parts and components of medium and heavy tanks. Existed only in blueprints. The 113 tank was a further development of the 112.

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.
