Naval Air Station Sanford was a naval air station of the United States Navy in Sanford, Florida, approximately 20 miles north of Orlando, Florida. Opening less than a year after the start of World War II, NAS Sanford's initial function was as an advanced training base for land-based patrol bombers, followed by carrier-based fighter aircraft. The air station briefly closed in 1946 and was placed in caretaker status until being reactivated in 1950. It eventually served as a Master Jet Base for carrier-based heavy attack and reconnaissance aircraft until 1969. After its closure, it reopened as civilian general aviation airport under various names with a non-Navy civilian airport identifier until finally transitioning to a scheduled air carrier airport under its current name of Orlando-Sanford International Airport. History Naval Air Station Sanford was commissioned as an active naval installation on 3 November 1942 and was initially assigned the airport codes NRJ and KNRJ. The base initially concentrated on advanced land-based patrol plane training, operating PV-1 Venturas, PBO Hudsons and SNB-2 Kansans. Peak wartime complement during 1943–1945 reached approximately 360 officers and 1400 enlisted men, both Navy and Marine Corps, with an additional complement of Naval Reserve officer and enlisted WAVES (Women Accepted for Volunteer Emergency Service) who served in air traffic control, meteorological services, administrative support, and aircraft maintenance. In 1943, training at NAS Sanford shifted to carrier-based fighter aircraft using the F4F, FM-1 and FM-2 Wildcat and F6F Hellcat. The air station also held oversight of an auxiliary airfield known as Outlying Field Osceola (OLF Osceola) approximately east-southeast of NAS Sanford. Decommissioned in 1946 and placed in a caretaker status, the base was recommissioned as Naval Auxiliary Air Station Sanford (NAAS Sanford) in 1950 in response to both the Korean War and the Cold War. Subsequently, redesignated as a full naval air station and renamed NAS Sanford once again, the installation initially served as a home station for carrier-based F9F Panther, F2H Banshee, AD Skyraider and AJ Savage attack aircraft assigned to the Atlantic Fleet. In the late 1950s, substantial upgrades followed in order to turn the air station into a Master Jet Base for the carrier-based Douglas A-3 Skywarrior (at the time, designated the A3D Skywarrior) nuclear attack aircraft of Heavy Attack Wing ONE (HATWING ONE). In addition to the Skywarrior, other associated sea-based and land-based training aircraft supporting A3D training, such as the F9F-T Cougar and P2V-3W Neptune,
