Comparing: KV-5 vs. AMX 50 100

Development began in June 1941 at the Leningrad Kirov Plant and was completed by August, but plans were interrupted due to the complicated situation on the front. The KV-5 was to utilize some components of the KV-1. A new turret was designed, incorporating the 107-mm ZIS-6 gun. Two roadwheels and a single support roller were to be added on each side. A new 1,200 h.p. diesel engine was being developed for the vehicle, however it was not completed in time and was replaced 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.
