Comparing: T21 vs. Type 64

A lightweight version of the T20 medium tank with the M7 elongated chassis. The vehicle was developed in the first half of 1943. Unlike the T20 tank, the T21 featured reduced armor and lightened armament. The vehicle never entered mass production nor saw service.

More than 50 of these vehicles were produced in Taiwan. All basic components of the vehicle were based on those of American vehicles. The Hellcat turret was mounted on the chassis of the M42 anti-aircraft vehicle, and the armament was the well-proven M1A2 gun. Only one Type 64 prototype survives today.
