The T28 Super Heavy Tank was an American heavily armored tank self-propelled gun designed for the United States Army during World War II. It was originally designed to be used 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 massive 100-ton vehicle was initially designated as Heavy Tank T28, it was later re-designated as the 105 mm Gun Motor Carriage T95 in 1945, and then renamed again in 1946 as the Super Heavy Tank T28. It first appeared in Girls und Panzer der Film.
