NSA Northwest Annex is located in Chesapeake, Virginia on the border of North
Carolina, 40 miles southwest of Virginia Beach, 35 miles south of Norfolk and
Portsmouth. Approximately 2/3 of the land is located in Virginia, while the remaining
1/3 is in North Carolina. NSA Northwest Annex originated in 1955, as the U.S.
Naval Radio Station as a receiving facility for naval activities. In 1970 it became
a part of the Naval Communication Station Norfolk.
Northwest Annexs mission is to coordinate and provide multi-service shore
activity support to 12 tenant activities and to the operations forces. It provides
environmental stewardship to the farm and wetlands in Southeastern corner of
Virginia, and crypto logic support to global U.S. Navy.
