The Americans’ Super Heavy Tank: T28

Most of the technology we feature here is either Soviet or secret Nazi stuff so it’s good to take a detour around the totalitarian regimes of World War II for a change and look at what the Americans were up to.

The heaviest tank developed in the United States during the war was the T28. It was conceived in the spring of 1945 and designed to break through the German defenses at the Siegfried Line — a string of bunkers and fortifications bordering France.

Only two T28s were ever built. The war was over before they could enter service. The slow moving behemoths weighed nearly one hundred tons and had an impractical range of less than twenty miles.

One of the prototypes was dismantled after the war had ended in the Pacific as well. The other was apparently abandoned in an Army depot and rediscovered in 1974 at Fort Belvoir, Virginia. It would go on to be exhibited at the Patton Museum of Cavalry and Armor in Kentucky where it remains up to this day.


  1. Without a turret its effectively a ‘self propelled gun’ and this one looked to be an answer to the German heavy tanks (60+tons) with heavy armor few allied tanks could deal with (other than being so numerous like Shermans that could buzz around while they were being picked off so that a few could get around behind where the armor was thinner.
