Raven Rock Mountain Complex (RRMC) is an underground continuity of government facility built by the U.S. government in the early 1950s. It is located about 14 km (8.7 miles) east of Waynesboro, Pennsylvania, and 10 km (6.2 miles) north-northeast of Camp David, Maryland. It is also called the Raven Rock Military Complex, or simply Site R. Other designations and nicknames include “The Rock”, NMCC-R (National Military Command Center Reservation), ANMCC (Alternate National Military Command Center), AJCC (Alternate Joint Communications Center), “Backup Pentagon”, or “Site RT”; the latter refers to the vast array of communication towers and equipment atop the mountain. Colloquially, the facility is known as an “underground Pentagon”

The RRMC was one of the “undisclosed locations” frequently used by Vice President Dick Cheney following the September 11 attacks.
