Comparing: Object 416 vs. Chieftain/T95

The development of the Object 416 started at the Construction Bureau of Factory No. 75 in the fall of 1949. The blueprint was developed by March 1950. Due to technical problems with the turret, a working prototype was not ready until April 1952. Improvements were made, and another prototype was built in the summer of 1953, but the vehicle never entered mass production.

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.
