Comparing: KV-4 by Kreslavskiy vs. 110

A project by M.I. Kreslavskiy. Due to the beginning of World War II, no prototypes were built. Existed only in blueprints.

From the mid-1940s to the 1950s, Soviet engineers attempted to modernize the IS-2 tank. The IS-2U variant, developed in November 1944, was conceived to have a reinforced frontal hull with a plate configuration resembling that of the IS-3. In the mid-1950s the design project was passed to China and became the basis of further Chinese tank development.
