NSGA Adak Disestablished, January 31, 1996

In July 1995, Naval Security Group activity (NSGA) Adak was slated for closure under the Base Realignment and Closure Act and deactivated on January 31, 1996. At the time of deactivation approximately 500 military and 50 civilian personnel were on the island. Officially, the military mission ended on March 31, 1997, and the station closed.

Naval Security Group activity (NSGA) Adak’s history dates back to the early days of World War II in the Pacific. Shortly after Japan bombed Dutch Harbor, located on Unalaska Island east of Adak near the mainland, and occupied the Aleutian Islands of Attu and Kiska, located to the west of Adak, the Navy established two major naval installation on Adak to counter the Japanese threat, Naval Air Station in May 1943 and Naval Operating Base in July 1943. In September 1943, the Naval Communication Supplementary Activity, Adak, NSGA Adak’s progenitor organization, was established to provide communications support to the location forces. The original activity, consisting of eight men, operated out of Quonset huts through the war’s conclusion until June 1948 when a new communication facility was constructed to replace the temporary wartime structures.
