The T34 Heavy Tank was an American design for a heavy tank. It was evolved from the T29 Heavy Tank and T30 Heavy Tank in 1945, sporting a 120 mm (4.72 in) modified anti-aircraft gun. Extra armor plating was applied to the rear of the turret bustle as a counterweight for the heavier 120mm T53[3][4] main gun. The vehicle was deemed too heavy and no production orders were placed.[5]


In 1945, encounters with heavy German tanks and tank destroyers such as the Tiger II and Jagdtiger lead to a new project to counter these new threats. It was built on the same chassis as the earlier T29 and T30, which was a lengthened version of the T26E3 chassis.[6]


There is at least one surviving example in National Armor and Cavalry Museum, Fort Benning, Georgia.[7][8]
