Comparing: KV-5 vs. AMX 50 100

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.

Development of this heavy tank started in 1945, and was influenced by German wartime tank designs. In 1950 a prototype with an oscillating turret and the 100 mm gun was manufactured. The vehicle never entered mass production nor saw service.
