Sugar Grove is the name of an American government communications site in West Virginia. It’s run by the National Security Agency. The site intercepts all international communications entering the Eastern United States. The Naval Information Operations Command is in charge of the operation.
It started in 1960 with a radio telescope that was to intercept Soviet radar and radio signals by reflecting the signals from the moon. The project got halted and began again in 1962 as a radio receiving station. Sugar Grove is located in an officially designated National Radio Quiet Zone. It covers 13,000 square miles in West Virginia and Virginia.
The zone was established in 1958 by Congress to facilitate its mission and the mission of the National Radio Astronomy Observatory located about 30 miles away. There is a small community called Sugar Grove near the site.
