The M36 tank destroyer, formally 90 mm Gun Motor Carriage, M36, was an American tank destroyer used during World War II. American soldiers usually referred to them as TDs for 'tank destroyers'. The M36 first served in combat in Europe in September 1944, and served until the end of the war; it also served during the Korean War, and in the armies of several other countries.
With the advent of heavy German armor such as the Panther and Tiger, the standard U.S. tank destroyer, the 3in Gun Motor Carriage M10, was rapidly becoming obsolete, because its main armament, the 3in M7 gun, had difficulty engaging these new tanks past 500 meters. This was foreseen, however, and in September, 1942 American engineers had begun designing a new tank destroyer armed with the M3 90 mm gun. This was several months before any Allied unit encountered a Tiger in combat, as the British First Army in Tunisia was the first western Allied unit to encounter the Tiger I in the leadup to the Battle of the Kasserine Pass at the start of 1943, and well over a year before any US unit encountered a Panther in combat.
The first M36 prototype was completed in March 1943, with a new turret mounting the 90 mm M3 gun on a standard M10 chassis. After testing, an order for 500 was issued. The prototype was designated T71 Gun Motor Carriage; upon standardization the designation was changed to 90 mm Gun Motor Carriage M36 in June 1944.
Like all US tank destroyers, the turret was open-topped to save weight and provide better observation. Postwar, a folding armored roof kit was developed to provide some protection from shell fragments, as with the M10. The M36 had a large bustle at the rear of its turret which provided a counterweight for the main gun. Eleven additional rounds of ammunition were stored inside the counterweight.
