Comparing: M18 Hellcat vs. Type 64 vs. Cromwell

Development started in 1942. In April 1943 the General Motors company produced the first prototypes. One of a few American tank destroyers manufactured on its original chassis, not on a tank chassis. The tank destroyer became the fastest armored vehicle, of this type, of World War II. A total of 2,507 vehicles were produced from July 1943 through October 1944.

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.

The Cromwell was developed in 1941–1942 by BRC&W. A total of 1,070 vehicles were mass-produced from late 1943 through 1945. They were extensively used by the British Army in the Northwest Europe Campaign of 1944–1945.
