Comparing: KV-5 vs. KV-4 by Kreslavskiy

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.

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