Comparing: KV-5 vs. 112

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.

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.
