The KV-2 Heavy Tank was a type of heavy tank developed and equipped by the Soviet Union in 1942. The KV-2 heavy tank is assembled with a new turret and artillery on the chassis of the KV-1 heavy tank. The tank has a total combat weight of 53 tons and a crew of 6 people. The main gun is the M10 152mm howitzer, which fires various types of shells including kill grenades, explosive grenades, and armor piercing shells. The firing rate of the artillery is 2-4 rounds per minute. The maximum range for indirect shooting is 12000 meters. The thickness of armor when launching armor piercing shells can reach 124 millimeters. Due to the unchanged power plant and increased combat weight, the unit power decreased, and the maximum speed of the tank was only 26 kilometers per hour.
The tank's square and tall turret is its prominent external feature. The KV-2 heavy tank began development at the end of 1939, was delivered for prototype testing in 1940, and was finalized for mass production and equipped with the Soviet army in February 1941, and put into practical combat. Discontinued production in October 1941 due to unforeseen circumstances
