In 1940, the United States Army established
Camp Seeley; its combat firing range site is within the current boundaries of the El Centro Naval Reservation. In 1941 the
Civil Aeronautics Administration offered to replace the small airport in
Imperial, California with a larger complex consisting of two 4,500ft runways. After the outbreak of World War II, the U.S. Navy leased the new airport and an adjacent 749 acres for additional construction. During this time the runways were extended and a third one was added. The expansion of MCAS El Centro was done by Vinson & Pringle and
Del E. Webb Construction Company out of
Phoenix, Arizona. MCAS El Centro was commissioned on July 23, 1943. During the war, the air station was used as a training base for new squadrons and as a facility for squadrons returning from overseas to reorganize and begin preparing to deploy again. On March 15, 1945 a Marine Corps Aerial Gunnery School was opened. MCAS El Centro was decommissioned on May 1, 1946, the same day it was taken over by the Navy for use as a
Naval Air Station. Fleet Air Gunnery Unit was opened. Through the years, Navy El Centro has had several names: Naval Air Facility, Naval Auxiliary Landing Field, Naval Air Station, and the National Parachute Test Range. For the first 35 years, the mission of NAF El Centro was devoted to aeronautical escape system testing, evaluation, and design. In November 1947, the Parachute Experimental Division from
Naval Air Station Lakehurst, New Jersey moved to El Centro. In 1951, the Joint Parachute Facility was established and consisted of the Naval Parachute Unit and the
U.S. Air Force (USAF) 6511th Parachute Development Test Group. The USAF remained part of El Centro's test organization for the next 27 years. On August 12, 1954, "[t]he 6511th Parachute Development Test Group redesignated as the 6511th Test Group (Parachute). The unit’s personnel did not change and its location remained at El Centro. Administrative and operational control remained with the
Air Force Flight Test Center" and the
Wright Air Development Center continued its technical supervision and test programming as before. In 2011,
Prince Harry, Duke of Sussex trained at El Centro and at
Gila Bend Air Force Auxiliary Field. While at both bases Harry trained on the
AgustaWestland Apache. ==Current operations==
