This M60 was built by combining the hull, main gun and cupola of the M-60A1 and the turret of an M48. It was an easy fun conversion to create a tank not available in model form. The M-48 hull need not be wasted. It can be converted to a bridge carrier or any number of other vehicles.
The M60 Patton first saw trials in 1957. It was designed to counter British reports of existing Soviet 100mm gun performance and reports of a new Russian tank armed with a 115mm gun. The urgent need to upgrade the 90mm gun in the M-48 Patton, due to the threat posed by newer Soviet tanks starting to equip the Warsaw Pact Forces. The US Army felt improved design provided an increased operational range and mobility, required less refuelling and servicing, and incorporated a 105 mm gun as main armament. The hull was a one piece steel casting divided into two compartments, the crew in the front, and the engine at the rear. (courtesy of Wikipedia)
