Comparing: KV-5 vs. VK 45.02 (P) Ausf. A

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 vehicle started in April 1942. The Krupp company received an order for construction of turrets. However, the prototype was never manufactured. The turrets were mounted on the first Tiger IIs.
