Comparing: KV-5 vs. VK 100.01 (P)

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.

A version of the Maus from June 4, 1942. The 120-ton predecessor of the superheavy tank existed only in blueprints and never saw service. The vehicle was only an intermittent stage in the development of the Maus.
