History

Facility for Department of the Navy and National Security Agency

Between 1917 and 1942, the complex housed 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)) in July 7, 1948, and redesignated as the Naval Security Station (NAVSECSTA) in September 21, 1950. Between June 1943 and December 1949, the Annex also housed Naval Code and Signals Laboratory.[2]

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[3] and after creation of the National Security Agency in 1952, the Station housed NSA headquarters and Security Branch, Naval Communications Division.[4]

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. Since 1971 it was redesigned as Naval Security Group Command Headquarters.[5]

The Communication Security Group (COMNAVSECGRU) headquarters staff officially moved from NAVSECSTA to Fort George G. Meade in November 1995.

Naval Computer and Telecommunications Command was present in the area between December 1990 and August 2001.

Department of Homeland Security headquarters

In 2002, the complex housed the Office of Homeland Security. After it was reformed into the United States Department of Homeland Security, the Nebraska Avenue Complex became the main headquarters for this department. Since 2005, the Nebraska Avenue Complex is owned by the General Services Administration.[9]
