It was developed on the chassis of the then-new Light Tank M5 (Stuart VI). The test vehicle had the standard M5 turret removed, and replaced with an open-topped turret, this vehicle was designated the T17E1 HMC.
Armament consisted of a new open-topped turret armed with a 75 mm M2 howitzer, later a 75 mm M3 howitzer, which were reworks of the M1A1 pack howitzer. It carried 46 rounds of 75 mm ammunition; types of ammunition carried were Smoke M89 and H.E. (high explosive) M48. Unlike the standard M5 Light tank, the M8 featured no hull-mounted or coaxial Browning M1919A4 .30-06 machine guns. A Browning M2HB .50-caliber machine gun was mounted on the right rear corner of the turret for local defense and anti-aircraft purposes. 400 rounds of .50-caliber were stowed on board for the M2HB. M4 Sherman tanks equipped with 105mm howitzers were available from late 1944 and gradually replaced the M8 Howitzer Motor Carriage.
The T17E1 HMC was ordered into production as the 75 mm Howitzer Motor Carriage M8 in April 1942. Production ran from September 1942, to January 1944. A total of 1,778 vehicles were produced.
The M8 saw action in the Italian Campaign, the Western Front, and in the Pacific Theater of Operations during the war. It was used by the French Union and State of Vietnam during the First Indochina War.
