Comparing: T34 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. The end of World War II lowered interest in heavy tank development, so the T34 never entered service. The prototypes were used in field trials.

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.
