Developed in the late 1960s, the M60A2 was an ambitious attempt to create a multi-tasking battle tank to accompany the M60A1, one capable of firing both conventional 152mm rounds or the new Shillelagh anti-tank missile. It featured a rotating command cupola with integral machine gun and a distinctive low-silhouette turret. Because of its technologically advanced design it was nicknamed “The Starship” by operators. It went into service in 1972, and all told, 526 were manufactured.
Despite the hype, the vehicle proved to be a major disappointment, as the new anti-tank missile lacked both range and armor penetration capability. Consequently, it was phased out of service rapidly, the hulls being converted to M60A3 standards or being used as the basis for bridgelayers. The gun system, however, was incorporated into the M551 Sheridan air-droppable tank after revision due to its light weight.
