Comparing: Löwe vs. KV-5

Development of this 70-ton super-heavy tank started on November 1, 1941. In February 1942, the Krupp company suggested the VK 70.01 avant project, later designated the Löwe ("Lion"). Several designs varying in configuration, armament, and armor, were drafted. However, the project was canceled after the Führer made the decision to develop even heavier tanks. No prototypes were ever built.

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.
