Comparing: Kirovets-1 vs. T32

The Kirovets-1 project (IS-3, prototype No. 1) was developed from July through November 1944. The prototype was built at the Chelyabinsk Kirov Plant in September–October 1944. From December 18 through December 24, 1944, the vehicle underwent trials at the NIBT proving grounds in Kubinka. After it was decided to manufacture a pilot series of the modified IS-2 with a hull proposed by engineers of Plant No. 100 and Сentral Research Institute-48, the work on the Kirovets-1 was discontinued.

An experimental World War II American heavy tank. Developed on the basis of the M26 Pershing and T29 tanks. Prototypes were built in 1946; however, the T32 never entered mass production.
