Naval Support Activity Northwest Annex, Virginia

A major security and communications site for the navy and other federal agencies, located on the border of North Carolina, 20 miles south of Norfolk. Among the facilities here is the receiving array for the shortwave radio radar system known as ROTHR (Relocatable Over the Horizon Radar) developed mostly by Raytheon, to track aircraft and ships. It receives signals bouncing back from a transmission plant near New Kent, Virginia, about 90 miles away. There is a second facility of this type in south Texas. The system is used extensively for anti-drug surveillance.
