Comparing: T1 Heavy Tank vs. T14 vs. Churchill III

Development of the T1E2 started in the U.S.A. in May 1940. The vehicle was designed as a heavy tank. The distinctive features of the vehicle were a cast hull and hydromechanical transmission with a double-disc hydraulic converter. Later, the tank was designated M6. A total of 9 vehicles (1 of which was experimental) were produced. The tank never saw action.

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.

A British tank supplied to the U.S.S.R. under Lend-Lease. The U.S.S.R. received a total of 301 vehicles, with some lost at sea during transport to Murmansk.
