The 17th Combat Sustainment Support Battalion was originally constituted on 25 July 1941 in the Regular Army as Headquarters and Headquarters Detachment, 7th Ordnance Battalion and was later activated on 1 August 1941 at Birmingham, Alabama. In March 1946 the Battalion was inactivated in India.

It was redesignated on 1 May 1965 as Headquarters, 7th Maintenance Battalion and activated on 15 July 1965 in Thailand. It was later reorganized and redesignated on 1 September 1966 as Headquarters and Main Support Company, 7th Maintenance Battalion.

The unit was redesignated on 16 October 1986 as Headquarters and Headquarters Detachment, 7th Maintenance Battalion, and activated at Schofield Barracks, Hawaii.

This marked the beginning of transformation for the 17th Corps Support Battalion. In 2004, 4th Quartermaster Detachment became part of 17th Combat Sustainment Support Battalion giving the unit the capability of a Theatre Airdrop Support Unit. As part of the reorganization of US forces in the Pacific and the transforamtion of the Army as a whole to the modular force structure, the 17th Corps Support Battalion was subsequently reorganized and redesignated as the 17th Combat Sustainment Support Battalion.
