The KW-2 is a Soviet heavy tank from the interwar period and the beginning of World War II. The first prototypes of this vehicle were created in 1940, and the car entered service in the same year. About 330 vehicles of this type were built during the production process. The combat weight of the tank was up to 52 tons. The drive was provided by a single diesel engine with a power of up to 600 HP. The main armament consisted of a 152mm M-10 gun and three 7.62mm DT machineguns.

The KW-2 vehicle was developed as a development of the KW-1 tank, and its production was the responsibility of the Leningrad Plant named after Kirov. The vehicle was created as a result of the experience of the Winter War (1939-1940), and its main task was to destroy the enemy's fortified resistance points and support their own infantry in the attack, not fight with tanks. For this reason, one can risk a statement that the KW-2 was essentially a self-propelled gun, and not a strictly senso tank. Despite their powerful armament and armor, the KW-2 vehicles suffered from high faults, especially in the drive train, which effectively reduced their combat value. Cars of this type were used primarily in the initial phase the German-Soviet war in 1941, although some of them served until 1945.
