T28 Super Heavy Tank

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.
