The IS-7 wasn't the only Soviet post-war super-tank. The Chelyabinsk Kirov Factory worked on Object 705, with similar characteristics, but a rear turret.

Aside from the original 65 ton design, ChKZ also had a 100 ton Object 705A in store, but we all know what happened to Soviet heavy tanks over 50 tons.
