for training in various aircraft, including the USAAF Lockheed P-38 Lightning, and the USN and USMC Grumman F4F Wildcat/General Motors FM-1 Wildcat, Grumman TBF/TBM Avenger, Grumman F6F Hellcat, and Consolidated PB4Y-2 Privateer. In 1946, the Navy decommissioned NAAS Brown Field and turned it over to San Diego County. The county ended up renting portions of the former base for use as a chicken farm and Chula Vista High School was established on the airport property in 1946. In 1951, the Navy reopened the airfield as NALF Brown Field, a naval auxiliary landing field, due to increased military activity stemming from the Korean War and the Cold War. In 1954, Brown Field was again commissioned and redesignated as a Naval Auxiliary Air Station, with facilities to support regular operations of Fleet aircraft, assigned missile programs, and field carrier landing practice. In 1955, NAAS Brown Field was home to one utility squadron (VU), two air antisubmarine warfare squadrons (VS), a fleet aircraft service squadron (FASRON), and a Regulus air missile unit. The following year, the base was home to two utility squadrons, VU-3 and VU-7, the headquarters for Commander, Utility Wing Pacific (COMUTWINGPAC), a FASRON 4 detachment, and a ground control approach unit. Aircraft that operated at NAAS Brown Field included the F6F Hellcat, F9F Cougar, SNB, R4D Skytrain, JD-1 Invader, P2V Neptune, and FJ Fury. On November 2, 1954, the Convair XFY-1 Pogo made a transitional flight from vertical takeoff to horizontal flight, then back to a vertical landing at NAAS Brown Field. In 1957, NAAS Brown Field was selected as a site for one of the Vanguard Earth Satellite Tracking Stations. On September 1, 1962, the Navy decommissioned NAAS Brown Field again and transferred ownership of Brown Field to the City of San Diego with the condition that it remain a public airport. During the mid to late 1960s, Pacific Southwest Airlines, an airline based in San Diego, trained its pilots at Brown Field using Piper Arrows, Comanches, Aztecs, and Beechcraft Bonanzas. PSA also had a contract to train Lufthansa pilots at Brown Field. In 1970, Lufthansa training moved to Phoenix, Arizona, where it remains today. Brown field is regularly visited by a Boeing 727 of IFL Group and other large private jets, mainly for customs, along with C-130s and F/A-18s of the USN, mainly due to the relatively long runway.
