Comparing: Chieftain/T95 vs. Panzer 58

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.

Swiss project of a medium tank with improved combat characteristics and the ability to fight in mountainous terrain, developed in 1953. The plans called for using the gun from the British Centurion tank. A total of two prototypes and ten vehicles were produced, but the vehicle never saw mass production.
