The Gun Motor Carriage, M18, popularly known as Hellcat, was designed from the start as a high-speed tank destroyer. When it was first suggested, the design called for a 37 mm tank gun. As the armor of German tanks increased, however, this was changed first for a 57 mm tank gun, and later the 76.2 mm tank gun being developed for the Medium Tank, M4.
Production of the Gun Motor Carriage, M18 started in July 1943, and it entered service in February 1944. By the time production ended in October 1944, 2507 vehicles had been produced. It served on the Western Front in both Northern Europe and Italy, where its combination of firepower and a reliable, agile chassis made it popular with its crews and feared by the Germans.
