Raven Rock Mountain Complex

DescriptionEdit

The installation's largest tenant unit is the Defense Threat Reduction Agency, and RRMC communications are the responsibility of the 114th Signal Battalion. The facility has 38 communications systems, and the Defense Information Systems Agency provides computer services at the complex. Additional names for the installation are Raven Rock Military Complex, National Military Command Center Reservation (NMCC-R), "Backup Pentagon", Site R, or "The Rock".

Site RTEdit

Site RT is the portion of the military installation with communication towers and buildings atop the mountain.

HistoryEdit

Raven Rock Mountain and the adjacent Jacks Mountain on the north were formed in the Ordovician Period geologic period, and Miney Branch flows west-to-east between them in the Potomac River Watershed. The 1820 Waynesboro-Emmitsburg Turnpike with toll station for the 1787 crossroad was constructed between the mountains, where the Fight at Monterey Gap was conducted after the 1863 Battle of Gettysburg (Stuart's artillery at Raven Rock Gap shelled Federal troops.) In 1870 copper ore was discovered to the north, and the nearby Fountain Dale Springs House was established in 1874. The scenic area's mountain recreation facilities to the west included the 1877 Pen Mar Park, the 1878 High Rock Tower, the 1885 Monterey Country Club, and several resorts (e.g., Blue Mountain House, Buena Vista Springs Hotels, & Washington Cliff House). The 1889 Jacks Mountain Tunnel on the Western Extension (Baltimore and Harrisburg Railway) was completed near Raven Rock Mountain, and nearby stations were at Blue Ridge Summit and Charmian. The Army's 1942 Camp Ritchie was built southwest of the resorts, and a local road was built eastward from Blue Ridge Summit and intersected the north-south Fountaindale-Sabillasville Road (the intersection now provides access to the RRMC main gate.)

Planning for a protected Cold War facility near Washington, D.C. began in 1948 for relocation of military National Command Authorities and the Joint Communications Service.

Super underground communications centerEdit

The planned deep underground communications center was identified in the original 1950 federal petition to seize the Beard Lot, a 1,500-foot-high, mile-long hill located at Fountaindale and extending east and south along the Waynesboro-Emmitsburg road, The "Declaration of Taking" for "United States of America Versus 1,100 Acres of Land" was filed at the Adams County courthouse on January 23, 1951, and made the government the official owner of the 280-acre tract seized from four properties (17 total properties had been requested by February 15—some only for temporary use.) South of and above the Carson service station on the Sunshine trail, bulldozers began work on January 19, 1951; by February 3 a roadway to the site had been leveled behind a farmhouse; and by February 24 underground work had commenced (40 men working "normally" on that date were only performing above-ground construction.) By May 26 the Army had named the landform Raven Rock Mountain ("Raven Rock" is a pillar landform to the north along the mountain range) and listed its elevation as 1,527 feet.

By October 17, 1951, there had been two deaths: one due to premature dynamite detonation in the Beard Lot tunnel, and another due to crushing of a power-shovel operator. The S. A. Healy Company was working on the alternate pentagon in November 1951, when Washington [announced] a cut-back in defense appropriations would affect the installation. On January 16, 1952, the government indicated that when completed, the bunker would have a standby group of approximately 100 personnel. Because of construction damage to the Sunshine Trail, the US said it would rebuild the trail in any fashion the state desired.

By March 29, 1952, more than 100 workers were striking from building additional Raven Rock housing at Camp Ritchie, which was to be a supplemental installation for the underground Pentagon at Fountaindale. No work was going on in the Raven Rock (Beard Lot) tunnel at that time. Local travelers having to bypass on the serpentine on the slope between Monterey and Fountaindale grew frustrated during the delay (the incomplete tunnel was derogatorily dubbed "Harry's Hole," for President Truman.) By April 7, 1952, United Telephone Company rights of way had been secured for four tracts, including one in Cumberland Township. Easements for three additional private tracts were filed by the government in December 1953 (a 1954 lawsuit against the U.S. by Alfred Holt was seeking $2,000 an acre for his 140-acre woodlot atop the Beard Lot [after] turning down an offer of $2,800 from the government.)

A 1952 Army history disclosed Raven Rock information. Three underground buildings were completed in 1953, the year a guard shelter burned on the installation. By April 1954, "Little Pentagon" development had cost $35,000,000.

Automatic activationEdit

After the 1954 Air Defense Command blockhouse was built at Ent Air Force Base where the joint 1955 Continental Air Defense Command was activated, in August 1955 OSD approved the automatic activation of Raven Rock's Alternate Joint Communication Center on declaration of air defense warning or notice of surprise attack (SAC similarly completed a bunker in 1955). The AJCC was equipped with command and control (C²) hardware by the end of 1955.

1956 War Room AnnexEdit

In July 1956 at Raven Rock, a joint War Room Annex was established and was operated by the Air Force, and Raven Rock's readiness was broadened in April 1957 [for] activation prior to emergency if JCS thought it necessary. By 1959, the services as well as JCS regarded Raven Rock as their primary emergency deployment center. For the Air Force, it served as Headquarters USAF Advanced, capable of receiving the Chief of Staff and key officers. After President Dwight D. Eisenhower expressed concern about nuclear command and control, a 1958 reorganization in National Command Authority relations with the joint commands was implemented. On 1 July 1958 Raven Rock's USAF facility, ADCC (Blue Ridge Summit), became one of the 33 NORAD Alert Network Number 1 stations (but with receive-only capability as at TAC Headquarters, Sandia Base, and the Presidio at San Francisco.) On 20 October 1960, the JCS instructed the Joint Staff to establish a Joint Alternate Command Element (JACE) for rotating battle staffs to Raven Rock for temporary duty. In November 1960, consoles at the Pentagon's Joint War Room became operational, and the Raven Rock JACE was activated on 11 July 1961 under USAF Brig. Gen. Willard W. Smith [with the 5] staffs permanently stationed in Washington and an administrative section at Ft. Ritchie —rotations began in October 1961 (Fort Ritchie also had the OSD Defense Emergency Relocation Site.) An expansion project by the Frazier – Davis – McDonald Company was underway in December 1961 at the "little Pentagon", and bunker personnel were evacuated during a 1962 fire. Pentagon construction to provide an entire JCS center at the Joint War Room opened the National Military Command Center (NMCC) in early October 1962. It was initially considered an interim center until a nearby Deep Underground Command Center (DUCC) could be completed after which Raven Rock would be phased out as superfluous, whichever version [50-man or 300-man DUCC] was chosen, but neither was built—nor were SAC's similar Deep Underground Support Center or NORAD's Super Combat Centers.

1962 ANMCCEdit

Raven Rock's joint War Room, USAF ADCC, and other facilities were designated the Alternate National Military Command Center (ANMCC) on 1 October 1962 when the Burroughs SS-416L Control and Warning Support System with the Semi Automatic Ground Environment had been deployed (Back-Up Interceptor Control began at North Bend AFS in December.) The term AJCC remained in use, only [for] the Army-managed communications complex. On 17 October 1962, DOD Directive S-5100.30 conceived the Worldwide Military Command and Control System with five groups of C² systems: the National Military Command System was the primary group (to serve the President/SECDEF/JCS) and was to contain the Pentagon NMCC, Raven Rock's ANMCC, 3 NEACP aircraft on 24-hour ground alert, 2 NECPA ships, and interconnecting communications—the Raven Rock bunker was hardened further to about 140 psi blast resistance by 1963 when the Cheyenne Mountain nuclear bunker was being completed for tbd psi. The USAF's subsequent IBM 473L Command and Control System with AN/FYA-2 Integrated Data Transfer Consoles and Large Panel Display Subsystem had equipment deployed at both the NMCC and ANMCC (a 2nd IBM 1410 computer was installed by December 15, 1966.)

1976 Telecommunications CenterEdit

The USACC Site R Telecommunications Center was designated in 1976, and the 1977 Alternate National Military Command and Control Center Improvement Program was worked on by the DoD Special Projects Office (later renamed Protective Design Center) for a new deep underground C² center with >3 mi (4.8 km) of air entrainment tunnels (cancelled in 1979.) After the 2001 September 11 attacks, Vice President Cheney used Raven Rock as a protected site away from President George W. Bush. The Raven Rock military installation was declared part of the Pentagon Reservation under 10 U.S.C. § 2674(g) and on May 25, 2007, DoD policy declared it is unlawful for any person entering in or on the property … to make any photograph, sketch, picture, drawing, map or graphical representation of the Raven Rock Mountain Complex without first obtaining the necessary permission" (cf. persons not entering or on the property such those of Google Maps.)

In 1977, the bunker had an Emergency Conference Room, and the Current Action Center was a military intelligence unit (an Air Force general was responsible for overseeing the installations' communications.)
