Comparing: KV-220-2 Beta Test vs. T14

Development of KV-220 on the basis of the KV heavy tank started in the summer of 1940. A prototype was built on December 5. Unlike other KV modifications, the tank featured an elongated hull, additional support roller, enhanced armor (100 mm), and a new turret with the 85 mm F-30 gun. In the fall of 1941, production of the KV-1 was discontinued. The vehicle received the mass-produced KV turret and was sent to the frontlines.

Developed between May 1942 and May 1943. Two prototypes were manufactured and tested. However, mass production was canceled, and T14 never became more than an experimental vehicle.
