Naval Surface Warfare Center, Indian Head Division (NSWC IHD)—also known as Naval Support Facility Indian Head—is a United States Navy installation in Charles County, Maryland. Part of Naval Sea Systems Command (NAVSEA), it is one of ten divisions of the Naval Surface Warfare Center (WFC). Its mission is to research, develop, test, evaluate, and produce energetics (i.e., explosives, propellants, pyrotechnics, reactive materials, related chemicals and fuels and their application in propulsion systems and ordnance). The U.S. Navy's presence in Indian Head dates to 1890, when the Bureau of Ordnance dispatched Robert B. Dashiell to establish a naval ordnance center. Dashiell served as Inspector in Charge of Ordnance there from 1890 to 1893. During World War I, the facility served as Naval Proving Ground, Indian Head. It is the United States Department of Defense (DoD)'s largest full-spectrum energetics facility. It employs more than 1,900 people, including more than 850 are scientists, engineers, and technicians that develop and sustain explosives, propellants, pyrotechnics, high-energy chemicals, and their application to weapons. In addition, NSWC Indian Head has the WFC's largest concentration of Ph.Ds working in energetics, including the highest number of synthetic chemists, detonation physicists, and formulation scientists.The Division pursues basic research, applied technology, technology demonstration, prototyping, engineering development, acquisition, low-rate production, in-service engineering/mishaps and failure investigations, surveillance, and demilitarization.As the U.S. Navy’s lead technical authority in the United States, NSWC Indian Head performs more than 60% of all Navy energetics workload, and has an unmatched record of 13 Navy-qualified explosives used in 47 Navy, Army, Air Force, and Marine Corps weapons. Seventy-five percent of all explosives deployed in U.S. weapons were developed by NSWC Indian Head. The main site for NSWC IHD is at Naval Support Facility Indian Head, a 3,500-acre peninsula along the Potomac River in southern Maryland, at the southern terminus of the Indian Head Highway. It also has operations in McAlester, Oklahoma; Colts Neck, New Jersey; Ogden, Utah; Louisville, Kentucky, and Picatinny, New Jersey.

The name of the base has varied over the years from Indian Head Proving Ground, to Naval Powder Factory, to Naval Propellant Plant, to Naval Ordnance Station, to the present Naval Support Facility Indian Head. The facility's main tenant activity is the Indian Head Naval Surface Warfare Center (NSWC/IH). Advanced research in energetic systems takes place at NSWC/IH. NSWC/IH absorbed the function of the closed Naval Ordnance Laboratory, formerly in White Oak. The base currently employs 3,700 people.
