Comparing: T34 vs. Löwe vs. KV-5

Developed in 1945 as a modernization of the T30 heavy tank. The vehicle was equipped with the 120 mm T53 gun and the new Continental AV-1790 engine. Because of the decline in heavy tank development after the end of World War II, the T34 never entered service. The prototypes were used in field trials.

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 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.
