the first M46 Pattons were deployed to South Korea. The tank proved superior to the much lighter North Korean T-34-85, which were encountered in relatively small numbers. By the end of 1950, 200 M46 Pattons had been fielded, forming about 15% of US tank strength in Korea; the balance of 1,326 tanks shipped to Korea during 1950 included 679 M4A3 Shermans, 309 M26 Pershings, and 138 M24 Chaffee light tanks. The M46 Patton was slower compared to other medium tank counterparts, but its maneuverability and powerful 90 mm gun made it a formidable weapon in the Korean Conflict. Subsequent shipments of M46 and M46A1 Pattons meant all remaining M26 Pershings were withdrawn during 1951, and most Sherman equipped units were also reequipped with the newer models of tanks. Post-Korean War Medium tanks M47 Patton The M47 Patton was intended to replace the M46 Patton and M4 Sherman tanks. It had a 90 mm gun and a crew of five. Although it was the primary tank of the US, it never saw combat while in US service. M48 Patton In early 1951, the U.S. initiated the design of the M48 Patton, designated the T-48 during its prototype stage, with a 90 mm cannon. The T48 featured a new turret, an improved suspension, and a redesigned hull in which the drive was to be seated in a centerline position, which also eliminated the bow machine gun as well as its operator. When the bow machine gunner position was removed, the M48 Patton became the first U.S. medium gun tank to have a centerline tank driver, no bow machine gun, and a 4-man crew. This contrasts all preceding tank designs, which had 5 or more crewmen per tank and the driver was off-set left or right at the front. T95 Medium Tank The T95 was an American series of prototype medium tanks developed from 1955 to 1959. These tanks used many advanced or unusual features, such as siliceous-cored armor, the APFSDS-firing 90 mm T208 smoothbore gun in a rigid mounting without a recoil system, a new transmission, and fire-control system, which incorporated the T53 Optical Tracking, Acquisition and Ranging (OPTAR) system, which worked by emitting pulsed beams of intense incoherent infrared light. Heavy tanks M103 heavy tank The M103 was manufactured at the Detroit Arsenal Tank Plant and the first units were accepted into service in 1957. The M103 was designed to counter
