Comparing: T95E6 vs. M6A2E1 vs. Object 260

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.

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.

A version of the Object 260 heavy tank. The design plans were completed in September 1945, but no prototypes were manufactured.
