Comparing: T26E4 SuperPershing vs. Object 416

To increase firepower, a new long-barrelled 90-mm gun was mounted on the T26E1 in January 1945. The prototype was designated the T26E4. Development was discontinued in January 1947 due to problems with the gun and the loading mechanism. A total of 25 vehicles had been built by that time, but never entered service.

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.
