were also assigned. The upgrades to the former NAAS to achieve status as a full-fledged NAS and Master Jet Base included lengthening of the main runway to with additional overruns of approximately on both ends; construction of additional new hangars; barracks and administrative support buildings for the air station, heavy attack wing, heavy attack squadrons, and Marine Barracks; installation or upgrades to precision approach radar/ground controlled approach (PAR/GCA), non-directional beacon (NDB) and tactical air navigation (TACAN) navigational aids; a robust storage and distribution system for JP-5 jet fuel (which relied on resupply via a railroad spur into the base); secure weapon/air-dropped ordnance storage facilities; a Navy Dispensary; a Navy Exchange complex and associated garage/service station/MiniMart; and morale, welfare and recreation (MWR) facilities that included a base movie theater, two swimming pools, lakeside recreational facilities and separate clubs for officers, chief petty officer and enlisted personnel pay grade E-6 and below. Like Pinecastle AFB (later renamed McCoy AFB), a Strategic Air Command installation approximately to the south, a commissary and full-fledged Naval Hospital facilities were not considered necessary at NAS Sanford due to the relatively close proximity of a commissary and USAF Hospital at Central Florida's other major military installation at the time, the nearby Orlando AFB (which was transferred to the U.S. Navy's control in December 1968 and renamed Naval Training Center Orlando), approximately to the south. NAAS / NAS Sanford also retained control of OLF Osceola into the early 1960s. However, OLF Osceola's 4000 to runways lacked sufficient length and pavement strength for contemporary carrier-based jet aircraft like the A3D. As a result, no improvements were made to the OLF's infrastructure and it was effectively abandoned as an operational facility. HATWING ONE consisted of nine Heavy Attack Squadrons (VAH), also known as HATRONs: VAH-1, VAH-3, VAH-5, VAH-6, VAH-7, VAH-9, VAH-11, VAH-12 and VAH-13. All were Fleet deployable units with the exception of VAH-3, which conducted Replacement Air Group (RAG) / Fleet Replacement Squadron (FRS) functions. In addition to the HATWING ONE squadrons, Air Development Squadron FIVE (VX-5), based at NAWS China Lake, California, also maintained a detachment (VX-5 Det Alfa) at NAS Sanford until the detachment's relocation to Kirtland AFB, New Mexico in 1962. Due to the Skywarrior's nuclear strike mission and the presence of an associated special weapons storage area at NAS Sanford, U.S. Marine Corps personnel provided both base security and special weapons storage area security, leading
