Truman Annex (formerly Naval Station Key West), Trumbo Point, Meacham Field (Key West International Airport), and Boca Chica, were now permanently etched in military history.In 1946, Air Test and Evaluation Squadron 1 (VX-1) was established at NAS Key West and for the next three decades conducted airborne antisubmarine warfare (ASW) systems evaluation out of Boca Chica, while Helicopter Antisubmarine Squadron 1 (HS-1) conducted Atlantic Fleet helicopter fleet replacement training in the SH-3 Sea King out of the former seaplane base at Trumbo Point.This continued until the late 1960s/early 1970s when these squadrons relocated to NAS Patuxent River, Maryland and NAS Jacksonville, Florida, respectively, with HS-1 having an intermediate base assignment to NAS Quonset Point, Rhode Island prior to its final relocation to NAS Jacksonville.
