About this Unit
Sugar Grove Station, located near Sugar Grove, West Virginia, was established in the early 1960s as a United States Navy installation. Its primary mission was to support the National Security Agency (NSA) with signals intelligence (SIGINT) operations, utilizing large radio antennas to intercept and monitor communications, including satellite transmissions during the Cold War. The station played a key role in global intelligence-gathering efforts until the early 21st century. In 2017, the base was officially closed and later repurposed for civilian use, marking the end of its military service.
