Nebraska Avenue Complex
The Nebraska Avenue Complex (NAC) is a U.S. Department of Homeland Security facility in Washington, DC. It is located at 3801 Nebraska Avenue NW in the AU Park neighborhood, and is bound by Nebraska and Massachusetts Avenue.
The campus was originally built for the Mount Vernon Seminary. Since 1943 it has been owned by the U.S. federal government, housing the Navy Communication Security Section and later the headquarters of the National Security Agency and later of the Department of Homeland Security.
Between 1917 and 1942, the complex was the third location of Mount Vernon Seminary.
By the end of 1942, the United States Department of the Navy took over the buildings, and formally acquired the land for $1.1 million US dollars on July 20, 1943. After they acquired the land, the area was renamed to the Communications Supplementary Annex.
Between February 1943 and July 1946, the Annex housed the Communication Security Section, which was relocated from the Main Navy Department building in Washington, D.C. It changed to Navy Communications Station (also known as NAVCOMMSTA Washington (NCSW)) on July 7, 1948, and was redesignated as the Naval Security Station (NAVSECSTA) on September 21, 1950. Between June 1943 and December 1949, the Annex also housed Naval Code and Signals Laboratory.
In September 1950, the Communications Security Group and the Communications Supplementary Activity Washington, merged to officially form the establishment of the Naval Security Group, headquartered at NAVSECSTA.
From 1951 onwards, the Station housed Armed Forces Security Agency units. After its redesignation as the National Security Agency (NSA) in 1952, the Station housed NSA headquarters and its Security Branch, Naval Communications Division.
In 1956, NSA Security Branch, Naval Communications Division was redesigned into Naval Security Group Headquarters Activity. By 1961 it changed to Naval Security Group Headquarters, Washington D.C. and in 1968 to Naval Security Group Command, Washington D.C. In 1971 it was redesigned as Naval Security Group Command Headquarters.
