Comparing: AMX AC mle. 46 vs. T28 Concept

Proposed plan for a heavy tank destroyer on the basis of the M4. Development was started in 1946. The configuration of the vehicle had a strong resemblance to the Jagdpanther. Existed only in blueprints.

The development of this heavy breakthrough tank began in September 1943. It was planned to utilize certain components of the M6 tank as well as the electromechanical transmission and 100-mm T5 gun, mounted in a turret of limited traverse with 203-mm armor protection. The vehicle was intended to assault the fortifications of the German "Siegfried Line" (known as the "Westwall" to the Germans). The U.S. land forces rejected the project during the design phase. The vehicle was later modified into the T95 heavy breakthrough tank.
