T34 Heavy Tank

The T34 Heavy Tank was an American design for a heavy tank. It evolved from the T29 Heavy Tank and T30 Heavy Tank in 1945, using the same chassis, but sporting a 120 mm (4.72 in) modified 120 mm Gun M1 anti-aircraft gun. Extra armor plating was applied to the rear of the turret bustle as a counterweight for the heavier 120mm T53 main gun. No production orders were placed for the T34, which was felt to be too heavy.
