The Missile Warning Center coordinates, plans, and executes worldwide missile, nuclear detonation, and space re-entry event detection to provide timely, accurate, and unambiguous strategic warning in support of the United States and Canada.
The BMEWS Central Computer and Display Facility built as an austere facility instead of the planned AICBM control center became operational on September 30, 1960, at Ent AFB when BMEWS' Thule Site J became operational. Site J's computers processed 4 RCA AN/FPS-50 Radar Sets' data, and alerts transferred via the BMEWS Rearward Communications System to the CC&DF for NORAD attack assessment and warning to RCA Display Information Processors at the NORAD/CONAD command center, SAC's Offutt AFB nuclear bunker, and The Pentagon's new National Military Command Center. DIPs presented impact ellipses and drove a "threat summary display" with a count of incoming missiles and a countdown of "Minutes Until First Impact" In July 1961 separate from the CC&DF, the surveillance center in New Hampshire "was discontinued as the new SPADATS Center became operational at Ent AFB" with the 496L Space Detection and Tracking System. In 1962 the Army's LIM-49 Nike Zeus program was assigned the satellite intercept mission, and the 1962 SECDEF assigned the USAF to develop the Satellite Intercept System which would use orbit data from a Space Defense Center. By December 15, 1964, NORAD had an implementation plan for a "Single Integrated Space Defense Center" for NORAD/CONAD to centralize both missile warning and space surveillance.
1967 Space Defense Center
The 1st Aero on February 6, 1967, moved operations to the Group III Space Defense Center, the integrated missile warning/space surveillance facility at the Cheyenne Mountain nuclear bunker Interim operations of the Avco 474N SLBM Detection and Warning System began in July 1970, and in 1972 20% of the Bendix AN/FPS-85 Phased Array Radar's surveillance capability "became dedicated to search for SLBMs".
1975 NORAD/ADCOM center
The NORAD/CONAD Missile Warning Center came under NORAD/ADCOM control in 1975 when the unified Continental Air Defense Command ended and in early 1972, the 427M improvement program was planned; e.g., After SAC assumed control of ballistic missile warning and space surveillance facilities on December 1, 1979, the MWC was in the same room as HQ NORAD/ADCOM J31's Space Surveillance Center The "NORAD Missile Warning and Space Surveillance System" was the general term for the entire network applied by the House's 1981 Armed Services Committee—the Core Processing Segment handled missile warning/space surveillance with three Honeywell H6080 computers, e.g., a NORAD Computer System H6080 for command and control and for missile warning functions. Circa 1986, the "missile and space surveillance and warning system" consisted of a space computational center and 5 sensor systems:
By 1981 Cheyenne Mountain was providing 6,700 messages per hour compiled via sensor inputs from the Joint Surveillance System, BMEWS, the SLBM "Detection and Warning System, COBRA DANE, and PARCS as well as SEWS and PAVE PAWS". During the 1991 Gulf War, the missile operations section that supported the MWC processed SCUD missile detections and interceptions for theater warning units. The Space and Warning Systems Center maintained "26 stovepipe systems" for USSPACECOM, NORAD, and AFSPC, and the Space Computational Center was replaced in 1992. In February 1995, "the missile warning center at Cheyenne Mountain AS undergoing a $450 million upgrade program as part of Cheyenne Mountain's $1.7 billion renovation package." At Cheyenne Mountain on September 11, 2001, Major Richard J. Hughes was the Missile Warning Center Commander and the Chief of the J7 Exercise Branch. In 2003, construction began for a new command center at Cheyenne Mountain to include Ground-Based Midcourse Defense—the "new Missile Correlation Center" was to have new consoles, mission system connectivity and communications capabilities.
Missile Correlation Center
The Missile Correlation Center and Space Control Center were in Cheyenne Mountain by March 4, 2005 when Patrick Mullin was the commander of the MCC, which by 2006 was receiving input from five Joint Tactical Ground Stations.
Missile Warning Operations Center
The 2006-8 Cheyenne Mountain Realignment divided MCC operations into NORAD/NORTHCOM's Missile and Space Domain at Peterson AFB and STRATCOM's facility in Cheyenne Mountain USSTRATCOM announced a 2007 plan to relocate the MWOC from Cheyenne Mountain to Schriever AFB In May 2010, USSTRATCOM decided to keep its missile warning center at Cheyenne Mountain, which had begun a $2.9 million renovation in January 2010
