The T28 Super Heavy Tank was an American super-heavy tank/assault gun designed for the United States Army during World War II. It was originally designed to break through German defenses of the Siegfried Line and was later considered as a possible participant in the planned invasion of the Japanese mainland.
The near 100-ton vehicle was initially designated a heavy tank. It was re-designated as the 105 mm Gun Motor Carriage T95 in 1945, and then renamed in 1946 as the Super Heavy Tank T28.
Only two prototypes were built before the project was terminated.
Name
Initially named Heavy Tank T28 when construction was authorized in 1944, the design did not fit in the usual categories of vehicles leading to reclassification. As it did not have its armament in a revolving turret, Ordnance requested a name change to 105 mm Gun Motor Carriage T95, the change becoming official in March 1945. However, due to its heavy armor and armament—while self-propelled guns in United States service were lightly armored—it was renamed Super Heavy Tank T28 in June 1946 by OCM 37058.<
