Warrenton Training Center

Warrenton Training Center is a classified U.S. government communications complex located in the state of Virginia. WTC has served multiple roles, most notably as a Central Intelligence Agency (CIA) signals intelligence facility, numbers station, and communications laboratory. The center also houses at least one underground "relocation" bunker that serves U.S. continuity of government purposes, and is a communications and signals intelligence training school for various federal departments and agencies, including the CIA, National Security Agency (NSA), Department of Defense and Department of State. Additionally, it is a relay facility for the Department of State's Diplomatic Telecommunications Service. The United States Army administers WTC on behalf of the U.S. government.
