Comparing: IS-6 vs. 112 vs. T-34-3

Plans for this vehicle were drawn up in the construction bureau of the Chelyabinsk Kirov plant from December 1943 to the summer of 1944. Further development and the construction of the first prototype took place at the Uralmash plant. However, the vehicle had no advantages over the other heavy tank designs under consideration, and its armor was seen as inferior to the IS-4 (Object 701), so the IS-6 was not selected for production.

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.

The T-34-3 medium tank was to be a modification of the T-34-2. Unlike the Type 59, the T-34-3 featured reduced armor and the 122-mm gun. The design was developed in 1957. However, mass production of the Type 59 was started in 1958, and the T-34-3 project was discontinued.
