Comparing: 110 vs. KV-5

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.

Development was started in June 1941 at the Leningrad Kirov Plant and completed by August, but the German invasion prevented development from progressing to the prototype stage. The KV-5 was expected to share some components with the KV-1. A new turret was designed, incorporating the 107-mm ZIS-6 gun. Early plans called for a new 1,200 hp diesel engine, but later adjustments, recognizing wartime disruptions, replaced this with two V-2K engines.
