Comparing: T95E6 vs. 121

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.

Development began in 1962 on a new medium tank based on the Type 59. The new tank was expected to feature improvements in firepower and armor protection. However, the project was canceled shortly after. Some technical innovations were applied later, in the development of the Type 69 tank. All 121 tank prototypes were destroyed during Chinese nuclear weapon testing.
