Massachusetts Institute of Technology, performed aerial photography missions, and helped to recover test torpedoes for the Navy torpedo station in Newport, Rhode Island. A sub-detachment operated from Elizabeth Field on Fisher's Island, New York. In 1944, NAS South Weymouth was the starting point for the first transatlantic crossings of non-rigid airships. United States Navy K-ships (blimps) K-123 and K-130 from Blimp Squadron 14 (also known as ZP-14, Blimpron 14, or "The Africa Squadron") left South Weymouth on 28 May 1944 and landed at Argentia, Newfoundland about 16 hours later. The two K-ships then flew approximately 22 hours to Lagens Field on Terceira Island in the Azores. The last leg of the flight was a ~20-hour flight to their destination with Fleet Air Wing (FAW) 15 at Port Lyautey, French Morocco (now Kenitra, Morocco). Blimps K-123 & K-130 were followed by K-109 & K-134 and K-112 & K-101 which left South Weymouth on 11 and 27 June, respectively, in 1944. These six blimps initially conducted nighttime anti-submarine warfare operations to complement the daytime missions flown by FAW-15 aircraft (PBYs and B-24s) using magnetic anomaly detection to locate U-boats in the relatively shallow waters around the Straits of Gibraltar. Later, ZP-14 K-ships conducted minespotting and minesweeping operations in key Mediterranean ports and various escort missions including that of the convoy carrying Franklin Roosevelt and Winston Churchill to the Yalta Conference in early 1945. Post-war demobilization and Cold War use South Weymouth was downgraded from a naval air station to a naval air facility on 9 August 1945 after Germany surrendered, thus ending the U-Boat threat to the east coast, and was thereafter used to store surplus naval aircraft that were awaiting final disposition. Many of these aircraft, especially Eastern/Grumman TBM/TBF Avengers, were subjected to elaborate cocooning and preservation methods in the two huge blimp hangars. During this period of South Weymouth's history the base was known as a naval aircraft parking station or "NAPS". Naval Air Facility South Weymouth was placed into caretaker status on 30 June 1949 and downgraded again to an auxiliary landing field or "ALF". In 1950 the Navy decided to close Squantum Naval Air Station, traditionally the focus of Navy and Marine Corps reserve aviation training in New England, and move the reserve program to ALF South Weymouth. The decision to close NAS Squantum resulted from increasing incidents of airspace conflicts with Boston's commercial airport (modern-day Logan International
