Comparing: STA-1 vs. Chieftain/T95

The first Japanese post-war tank was developed on the basis of U.S. vehicles. The STA-1 was developed, taking into consideration Japanese terrain, rail network specifications, and anthropometric data of Japanese tankers. Only one prototype was built, in December 1956.

Development of the FV4201 Chieftain allowed for the interchangeability of guns with the U.S. T95 tank by means of exchanging turrets. The project was discontinued because of numerous problems with training crews to master two artillery systems.
