T57 Heavy Tank

A project for a heavy tank with an oscillating turret and automatic loader, developed from 1951. Experimental turrets for 120 mm and 155 mm guns were manufactured by 1957. However, the project was deemed unsuccessful and development was discontinued.

T110E5

Developed from 1952 as a heavy tank with more powerful armament, compared to the T-43 (M103). Restrictions were placed on the vehicle sizing as the tank was supposed to pass through the narrow tunnels of the Bernese Alps. Several designs were considered, but the project was canceled. No vehicles were ever manufactured.

T95E6

Some military analysts deemed the experimental tanks of the T95 series to be undergunned. In order to increase the tank's firepower, a new, heavier turret, designated T96, was to be mounted on the hull. This would allow replacement of the 105-mm gun with a 120-mm gun. However, development proved unsuccessful, and the project was canceled on July 7th, 1960. Only one dummy vehicle was built.

M103

The development started in 1948. In 1952 the order was placed for production of 300 vehicles to fight in the Korean War. The tank was designated as M103.

T34 Independence

In 1945 two prototypes of the T30 were armed with 120 mm guns and redesignated as the T34 Heavy Tank. The vehicle never entered mass production, nor saw service. The T34 Independence is a holiday version featuring special camouflage.

T34

Developed in 1945 as a modernization of the T30 heavy tank. The vehicle was equipped with the 120 mm T53 gun and the new Continental AV-1790 engine. Because of the decline in heavy tank development after the end of World War II, the T34 never entered service. The prototypes were used in field trials.

T32

An experimental World War II American heavy tank. Developed on the basis of the M26 Pershing and T29 tanks. Prototypes were built in 1946; however, the T32 never entered mass production.

M6A2E1 EXP

The M6A2E1 was a further development of the T1 and M6 heavy tanks. Developed in August 1944, the vehicle had a larger turret and the 105-mm gun. Never saw mass production.

T26E5

Successful combat use of the assault M4A3E2 tank with enhanced armor spurred the decision to create a similar modification of the M26. Chrysler started production of the improved vehicles in July 1945. Trials revealed that it was necessary to reduce its off-road speed to avoid damage to the suspension. A total of 27 vehicles were manufactured to take part in trials and experiments.

Chrysler K

A project of the Chrysler Corporation, developed in the summer of 1946. The vehicle featured a number of design solutions that were not typical of U.S. tank-building. In particular, the Chrysler K was to have its transmission and engine located in the front, and the armament compartment—in the rear part of the hull. All crew members would have sat in the turret. It is thought that this project was the first U.S. project to position the driver in the turret. It was not supported by the army due to limited funding.

T29

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.

M6A2E1

The M6A2E1 was a further development of the T1 and M6 heavy tanks. Developed in August 1944, the vehicle had a larger turret and the 105-mm gun. Never saw mass production.

M6

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

T1 Heavy Tank

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.

T14

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.
