Comparing: T34 vs. IS-5 (Object 730)

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.

The development of the vehicle was started in 1949 by the Design Bureau of the Chelyabinsk Kirov Plant under the supervision of Joseph Kotin. In 1950 a preproduction batch of 10 vehicles was launched. After the vehicle underwent all trials and received upgrades, it was adopted for service in 1953 under the designation IS-8.
