Tysons Corner Communications Tower, also known as Site E, is a classified United States military microwave tower located in Tysons Corner, Virginia. The tower is administered by the United States Army from Fort Belvoir.
The specific uses of the tower today are classified. It is rumored to be a government intelligence numbers station, although others argue that the tower's communications equipment is obsolete. Indeed, several microwave antennas have been removed from the tower, include those pointed to Mount Weather Emergency Operations Center, although it is speculated that these have been replaced by fiber-optic cable links. Additionally, the tower is reportedly connected by underground fiber-optic cable to Warrenton Training Center, which is a continuity of government facility as well as a Central Intelligence Agency communications facility.
