Sugar Grove Station

[citation needed][2] In April 2013, the Chief of Naval Operations ordered that the NAVIOCOM support base be closed by September 30, 2015, as "a result of the determination by the resource sponsor National Security Agency to relocate the command's mission.

"[3][4] The naval base is being repurposed as a privately owned healthcare facility for veterans, while the NSA listening station, to the south, continues to operate.

Naval Radio Station Sugar Grove was activated on May 10, 1969, and two Wullenweber AN/FRD-10 Circulary Disposed Antenna Arrays (CDAAs) were completed on November 8, 1969.

The zone was established by Congress in 1958 to facilitate its mission and that of the National Radio Astronomy Observatory located 30 miles (48 km) away at Green Bank in Pocahontas County, West Virginia.

[12] In 2017, the second auction resulted in a $4 million purchase by an Alabama-based investment group with plans to convert the base into a healthcare facility for active-duty military, veterans, and their families.
