The Chidlaw Building is a former United States Air Force facility located in the Knob Hill neighborhood of Colorado Springs, Colorado. The building was close to, but not within, the Ent Air Force Base complex, and was leased by the military for several decades, housing headquarters for several military commands, starting with the Air Defense Command (ADC) and the North American Aerospace Defense Command (NORAD). When Chidlaw was completed, personnel from multiple locations, including the Ent Air Force Base, were consolidated into the new building.
In 1993, the building was renovated into an office building and housed Premiere Global Services (PGi) as its main tenant. Once PGi moved out in 2011, building occupancy dropped to 45%, but still included a customer service center for Time Warner Cable. The building went into foreclosure in 2012. [2]
By April 1958, North American Aerospace Defense Command (NORAD) informed the Joint Chiefs of Staff of the need for a Ballistic Missile Early Warning System (BMEWS) to be located in a new, underground Combat Operations Center in the Colorado Springs, Colorado area. Building the Combat Operations Center within a granite mountain in the Colorado Springs area was shown to be the best solution at the lowest cost. NORAD also concluded that it was important to have related commands nearby, such for joint planning and combat readiness, [3] : 154 but not so close that they could be destroyed easily at the same time. [3] : 155 On 18 March 1959, and upon review of findings by the Corps of Engineers, the Joint Chiefs of Staff determined that Cheyenne Mountain should be the location of the underground facility (Cheyenne Mountain Complex). [3] : 155–156
While the construction was performed, an interim location for the Zone of Interior BMEWS equipment was to be established in the basement of a building near the base. That way, BMEWS equipment could be utilized as early as 1961 and until the new Combat Operations Center was completed. [3] : 158 NORAD said that the only initial active Advanced Intercontinental Ballistic Missile (AICBM) system that could be ready in sufficient numbers to be effective by 1964 was the Nike Zeus, which would integrate the use of radar, anti-missile missiles and atomic warheads. [3] : 148 In December 1958, NORAD called for the hasty development of the anti-Intercontinental ballistic missile (ICBM) system, the WS-117L reconnaissance satellite. [3] : 157–159 The Clear Air Force Station system in Alaska was scheduled to be completed in 1961, but the hardened Combat Operation Center would not be operations until sometime after that. So, an interim BMEWS central display facility was built as an annex to the Ent Combat Operation Center. It would not, though, have an interim satellite prediction computer, as that would be placed in the new Cheyenne Mountain facility. In the meantime, each radar site's computer would make its own calculations. [4] : 93–94 The Ent Air Force Base COC annex would not be completed until December 1960, so an interim solution was to be implemented at Thule by September 1960 and until December 1960. [4] : 94 SPADATS was transferred to NORAD and CONAD command in November 1960 and was activated at the Ent Air Force Base on 14 February 1961 by the 1st Aerospace Surveillance and Control Squadron, which was also responsible for the operation of the BMEWS Central Computer and Display Facility in the NORAD Operations Center. SPADATS was dedicated at Ent on 3 July 1961, just a few months after excavation began on Cheyenne Mountain. [5]
The plan to use an off-base leased facility was implemented for the Combined Operations Center[ citation needed ] when the Cheyenne Mountain Air Force Station was delayed and an earlier Semi-Automatic Ground Environment command post was needed as an interim Air Defense Operations Center for combining NORAD's attack warning and CONAD's weapons direction missions.[ citation needed ]
The Chidlaw Building, built in 1963 at 2221 East Bijou Street, Colorado Springs as the headquarters for the Aerospace Defense Command and North American Aerospace Defense Command (NORAD), [2] [7] was named for retired Air Force Gen. Benjamin W. Chidlaw. The 300,000 square feet (28,000 m2) building was built with fortified walls, an auditorium for 174 people, two electrical substations, and elaborate heating and cooling systems. [2] Of three floors, one is underground, and the only windows were those in the lobby. [6] : 491
The Chidlaw Building consolidated Air Defense Command personnel from 14 different locations, including the Ent Air Force Base, into one location. [7] It had command sections for NORAD headquarters, ADTAC headquarters, and an ADTAC command section, and a secure communications complex with links to the Cheyenne Mountain Air Force Station. Facilities included a printing plant, exercise room, cafeteria, and executive dining room. There were also a food store, small base exchange, commercial bank, and Ent Credit Union on site. There was a civilian guard force. [6] : 492 Department of Defense graphic artist Terrance Patterson was commissioned to make nine paintings of the evolution of air and space for the building. When the military vacated the building, the paintings were moved to the lobby of the Cheyenne Mountain Air Force Station technical support building. [8]
The Chidlaw Building's Combined Operations Center was transferred from the Ent AFB combat center.[ citation needed ] It had an IBM 1410 computer in 1965 for systems analysis, and air defense consoles presenting data from various Air Divisions (e.g., for the Goose Air Defense Sector in Canada).[ citation needed ] Systems which transmitted data to the building[ citation needed ] included AN/FSQ-8 Combat Control Centrals at Semi-Automatic Ground Environment (SAGE) Combat Centers which forwarded the divisional air defense status to NORAD. [9]
As the highest echelon of command and control for the SAGE Defense System, the Chidlaw Building was the primary node of NORAD's Alert Network Number 1.[ citation needed ] The network was to warn military installations with low rate teletype data, like SAC Emergency War Order Traffic [10] that included Positive Control/Noah's Ark instructions through northern NORAD radio sites to confirm or recall SAC bombers if SAC decided to launch the alert force before receiving an execution order from the JCS. [3] : 120–121 The NORAD Combined Operations Center operations was transferred from Ent Air Force Base to the Cheyenne Mountain Complex on 20 April 1966. Space Defense Center at Cheyenne Mountain Complex became fully operational on 6 February 1967. [5]
In addition to the Combined Operations Center, the Chidlaw Building housed the headquarters for several military commands:
The Chidlaw Building was an off-site building of the Ent Air Force Base that was leased under an "expensive rental arrangement". The Ent Air Force Base was a complex in Colorado Springs without room for expansion, so the base was closed down in 1975 and became an annex to Peterson Air Force Base. [17] In December 1976, personnel from Ent were moved to Chidlaw and Peterson Air Force Base. [11] : 22 By 1979, the General Services Administration had leased the Chidlaw for use by the Air Force. A plan calling for a realignment, or distribution, of the Aerospace Defense Command responsibilities and assets to the Tactical Air Command, Strategic Air Command, and the Air Force Communication Services. It also included distributing personnel from Chidlaw to other military locations and deactivating the Aerospace Defense Command/. [18]
By the late 1980s, the functions performed within the building were moved to other military installations. [2] USSPACECOM and NORAD headquarters were moved to Peterson Building 470. [6] : 667
When preparing to move furniture from Chidlaw's Air Defense Command war room to Peterson Air Force Base, Tony Wells was surprised to find the chair that President John F. Kennedy sat in when he received a Cheyenne Mountain briefing on 5 June 1963. The chair, which had a plaque affixed to the underside of the chair to commemorate the occasion, was then placed in the Peterson Air and Space Museum. [19]
Several million dollars were spent since 1993 to gut the building, make numerous improvements and turn it into office space. Lars Akerberg purchased the building in 1993, and Premiere Global Services (PGi), which operated a teleconference center, became its largest tenant. [2] [20]
The building went into foreclosure in early 2012 with an occupancy rate of only 45% after Premier Global had moved out the previous year. According to Turner Commercial Research, the city's office vacancy rate (14.5%) is almost three times what it was in 2000. Buildings like the Chidlaw struggle to compete with modern buildings that are more conveniently located either along the Interstate 25 corridor or within downtown Colorado Springs. [2]
Current tenants as of 2022:
North American Aerospace Defense Command, known until March 1981 as the North American Air Defense Command, is a combined organization of the United States and Canada that provides aerospace warning, air sovereignty, and protection for Canada and the continental United States.
The Cheyenne Mountain Complex is a United States Space Force installation and defensive bunker located in unincorporated El Paso County, Colorado, next to the city of Colorado Springs, at the Cheyenne Mountain Space Force Station, which hosts the activities of several tenant units. Also located in Colorado Springs is Peterson Space Force Base, where the North American Aerospace Defense Command (NORAD) and United States Northern Command (USNORTHCOM) headquarters are located.
Ent Air Force Base was a United States Air Force base located in the Knob Hill neighborhood of Colorado Springs, Colorado. A tent city, established in 1943 during construction of the base, was initially commanded by Major General Uzal Girard Ent (1900–1948), for whom the base is named. The base was opened in 1951.
The RCA 474L Ballistic Missile Early Warning System was a United States Air Force Cold War early warning radar, computer, and communications system, for ballistic missile detection. The network of twelve radars, which was constructed beginning in 1958 and became operational in 1961, was built to detect a mass ballistic missile attack launched on northern approaches [for] 15 to 25 minutes' warning time also provided Project Space Track satellite data.
Peterson Space Force Base, previously Peterson Air Force Base, Peterson Field, and Army Air Base, Colorado Springs, is a United States Space Force base that shares an airfield with the adjacent Colorado Springs Municipal Airport and is home to the North American Aerospace Defense Command (NORAD), the Space Force's 21st Space Wing, elements of the Space Force's Space Systems Command, and United States Northern Command (USNORTHCOM) headquarters. Developed as a World War II air support base for Camp Carson, the facility conducted Army Air Forces training and supported Cold War air defense centers at the nearby Ent Air Force Base, Chidlaw Building, and Cheyenne Mountain Complex. The base was the location of the Air Force Space Command headquarters from 1987 to 20 December 2019 and has had NORAD/NORTHCOM command center operations since the 2006 Cheyenne Mountain Realignment placed the nearby Cheyenne Mountain Complex on standby. On 26 July 2021, the installation was renamed Peterson Space Force Base to reflect its prominent role in the new space service.
Aerospace Defense Command was a major command of the United States Air Force, responsible for air defense of the continental United States. It was activated in 1968 and disbanded in 1980. Its predecessor, Air Defense Command, was established in 1946, briefly inactivated in 1950, reactivated in 1951, and then redesignated Aerospace rather than Air in 1968. Its mission was to provide air defense of the Continental United States (CONUS). It directly controlled all active measures, and was tasked to coordinate all passive means of air defense.

The Aerospace Defense Center (ADC) was a unit of the United States Air Force. It was under the command of the general that also commanded both North American Aerospace Defense Command and Aerospace Defense Command (ADCOM). The center included the Office of Astrodynamics (ADC/DO6) and the Office of History.
Cheyenne Mountain Space Force Station (CMSFS) is located in Cheyenne Mountain on the Front Range of the Rocky Mountains in unincorporated El Paso County, Colorado, next to Colorado Springs, The Cheyenne Mountain Complex, an underground facility within Cheyenne Mountain SFS, was first built for the North American Aerospace Defense Command (NORAD) Combat Operations Center, though NORAD moved day-to-day operations to its headquarters on Peterson AFB in 2006. However, day-to-day operations were moved back in 2011 after a major overhaul and renovation.
The Space Defense Center (SDC) was a space operation center of the North American Aerospace Defense Command. It was successively housed at two Colorado locations, Ent Air Force Base, followed by Cheyenne Mountain's Group III Space Defense Center The 1st Aerospace Control Squadron manned the SDC at both locations, which used the Electronic Systems Division's 496L System for processing and displaying data combined from the U.S. "Air Force's Space Track and the Navy's Spasur" (NAVSPASUR).
The Federal Building, originally the Burroughs Building, was a Cold War military computer systems building on the Ent Air Force Base in Colorado Springs. It was built in 1962 to be used by Burroughs Corporation for its project to build an automated facility to take input, like satellite and radar information, and instantaneously assess its degree of combat importance. The program was designed in conjunction with Air Force 425L System Project engineers and was an important component in North American Aerospace Defense Command (NORAD)'s command and control system. It was an Ent Air Force Base building until 1975 when the base was inactivated. It then became an off-base installation to the Peterson Air Force Base. Over the next several decades there were varying uses for the building by the federal government. After 2007, the building was vacated and in 2009 it was sold.
Continental Air Defense Command (CONAD) was a Unified Combatant Command of the United States Department of Defense, tasked with air defense for the Continental United States. It comprised Army, Air Force, and Navy components. It included Army Project Nike missiles anti-aircraft defenses and USAF interceptors. The primary purpose of continental air defense during the CONAD period was to provide sufficient attack warning of a Soviet bomber air raid to ensure Strategic Air Command could launch a counterattack without being destroyed. CONAD controlled nuclear air defense weapons such as the 10 kiloton W-40 nuclear warhead on the CIM-10B BOMARC. The command was disestablished in 1975, and Aerospace Defense Command became the major U.S. component of North American Air Defense Command (NORAD).
The Missile Warning Center (MWC) is a center that provides missile warning and defense for United States Space Command's Combined Force Space Component Command, incorporating both space-based and terrestrial sensors. The MWC is located at Cheyenne Mountain Space Force Station.
Construction of the Cheyenne Mountain Complex began with the excavation of Cheyenne Mountain in Colorado Springs, Colorado on May 18, 1961. It was made fully operational on February 6, 1967. It is a military installation and hardened nuclear bunker from which the North American Aerospace Defense Command was headquartered at the Cheyenne Mountain Complex. The United States Air Force has had a presence at the complex since the beginning, the facility is now the Cheyenne Mountain Space Force Station, which hosts other military units, including NORAD.
On 21 September 1979, Major General John L. Piotrowski assumed the duty of Tactical Air Command Deputy Commander for Air Defense. (10:xxxi) General Piotrowski and his staff were initially stationed in the Chidlaw Building, Headquarters ADCOM, Colorado Springs, Colorado.
