Holston Army Ammunition Plant (HSAAP) manufactures Research Department Explosive (RDX) and High Melting Explosive (HMX) for ammunition production and development. It is government-owned and contractor-operated (GOCO) facility.
The Holston Army Ammunition Plant, also known as the Holston Ordnance Works, was constructed by Tennessee Eastman in Kingsport, Tennessee to manufacture explosives during World War II.
BAE Systems' division Ordnance Systems, Inc. currently operates the plant under a 25-year facilities use contract. On May 12, 2011, the Army announced that BAE Systems had won the contract to operate Radford Army Ammunition Plant in nearby Radford, VA as well.
Capabilities of the plant include: production and development of insensitive munitions explosives; synthesis and manufacture of high explosives; recrystallization and purification from organic solvents; melt-cast, cast-cured, pressed and extruded explosives formulation; explosives performance testing; full-spectrum explosives research and development capability; and custom and fine chemical manufacture for the defense industry.
