T58 Heavy
#70689

Description:
The idea for the tank that would become the T58 was proposed in October 1951, not long after development of the 120mm T57 tank had begun. A paper from April 1952 laid out recommendations for the T58’s build, which included a 155mm gun that could fire HEAT and HESH rounds, a six-round autoloader, and construction of two prototype oscillating turrets that could be mounted to a T43E1 chassis. Due to manufacturing delays and changes in American military doctrine, both the T58 and T57 projects were cancelled in January 1957.
