Comparing: T1 Heavy Tank vs. M6 vs. T29

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 from 1940 through 1942, with a total of 40 vehicles manufactured from November 1942 through February 1944. It never saw action.

Development of this experimental heavy tank started in 1944. The prototype was built in 1947. The vehicle featured the 105 mm T5E1 gun. After the war, the mass production of heavy tanks was deemed unreasonable, and only a few prototypes of this vehicle were built.
