The T54 was a series of prototype American tanks of the 1950s with three different turrets, all armed with a 105 mm gun, mounted on the M48 Patton chassis.

[2] The turret on the T54E1 was similar to that of the T69 in its oscillating design and in that it held a crew of three and a nine-round drum autoloader under the gun.

The T54E1 was abandoned in 1956 and in 1957 the entire project was cancelled in favor of the T95 Medium Tank.

[2] In December 1950, the Army Equipment Development Guide recommended that a 105 mm tank gun be pursued.

By 6 July 1951, OTCM (Ordnance Technical Committee Minutes) 33842 officially initiated the development project with two new vehicles designated: the 105 mm gun tank T54, and the 105 mm gun tank T54E1.
