Naval Air Station South Weymouth, was an operational United States Navy airfield from 1942 to 1997 in South Weymouth, Massachusetts. It was first established as a regular Navy blimp base during World War II. During the postwar era the base became part of the Naval Air Reserve Training Command, hosting a variety of Navy and Marine Corps reserve aircraft squadrons and other types of reserve units. Environmental contamination from wastes stored in 3 landfills was detected in 1986, and since 1993 the site has been on the National Priorities List of Superfund sites. Numerous remedies and long term monitoring of ground water are in place. Since 2005, over 600 acres have been transferred to the affected towns for reuse, and in 2011 the Navy signed a $25 million contract to transfer its remaining land.World War IIIn 1938, the site was surveyed as a possible location for a municipal airport, which was never built. Construction work on the base began in September 1941 and the base was commissioned as the United States Naval Air Station South Weymouth on 1 March 1942. During World War II the base's primary mission was to provide support for anti-submarine blimp operations. In its original as-built format South Weymouth's main facilities consisted of two gigantic blimp hangars, the earlier (LTA Hangar One or "The Big Hangar") of steel construction and the second (LTA Hangar Two) of the more common World War II standardized design of nearly all-wooden construction employed to conserve rationed metals. The base also had a 2000ft Macadamized blimp landing mat, six mooring circles, and a 4500ft cinder-surfaced turf runway.
