T28 Concept

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 (called the Westwall by the Germans). The U.S. land forces rejected the project during the design phase. The vehicle was later modified to the T95 heavy breakthrough tank.
