Aerospace Defense Command (Air Defense Command before 1968) was a Cold War military organization established as one of the initial United States Air Forces major commands. Activated in 1946 by the United States Army Air Force, its mission was to organize and administer the integrated air defense system of the Continental United States (CONUS), exercise direct control of all active measures, and coordinate all passive means of air defense.
Overview
During the 1946 transition to an independent Air Force military branch, the United States Army Air Forces activated Air Defense Command (ADC) with a Numbered Air Force of the former Continental Air Forces, from which it took its mission of air warning and air defense. After the 1947 USAF transfer, ADC become part of Continental Air Command (ConAC) on 1 December 1948. ConAC gradually assumed direct charge of ADC air defense components and ADC inactivated on 1 July 1950 at the beginning of the Korean War. On 10 November 1950, Generals Vandenberg and Twining notified General Whitehead that "the Air Force had approved activation of a separate Air Defense Command [from CONAC] with headquarters on Ent"[1]:140 with the mission to stop a handful of conventionally armed piston engine-powered bombers on a one-way mission.
With advances in USSR bombers, ADC completed improved radar networks and manned interceptors in the 1950s, and at the end of the decade computerized Air Defense Direction Centers to allow air defense controllers to more quickly review integrated military air defense warning (MADW) data and dispatch defenses (e.g., surface-to-air missiles in 1959). ADC began missile warning and space surveillance missions in 1960 and 1961, established a temporary missile warning network for the 1962 Cuban Missile Crisis, and in 1968 was redesignated Aerospace Defense Command (ADCOM).
In 1975, ADCOM became a specified command and the United States' executive agent in the North American Air Defense Command—the single CINCNORAD/CINCAD commanded both. ADCOM's last surface-to-air missiles were taken off alert in 1972, and the Federal Aviation Administration took over many of ADCOM's SAGE radar stations. In 1979 the number of manned interceptors had dropped to tbd, and on 1 October 1979 ADCOM interceptors/bases and remaining air warning radar stations transferred to Tactical Air Command. ADCOM's missile warning and space surveillance installations transferred in 1979 to SAC/SX,[2]) and the Air Force Element, NORAD/ADCOM (AFENA)[2] was redesignated the Aerospace Defense Center.[3]
Within a few years, the Aerospace Defense Center, the ADCOM specified command organizations, along with SAC's missile warning and space surveillance installations became part of the 1982 Space Command which activated its headquarters in the same building where ADCOM had been inactivated on 31 March 1980.
Chronology of major events

Background
Continental United States air defense forces during World War II were initially under the command of four military organizations--Northeast Air District, Northwest Air District, Southeast Air District, and Southwest Air District established on 16 January 1941 before the Pearl Harbor attack.[5] The four air defense districts also handled USAAF "participation with Army Ground Forces in combat training maneuvers" and "organization and training of bomber, fighter and other units and crews for assignments overseas" after individual crewmember training by the Western and Eastern Technical Training Commands.[5] The air defense districts were redesignated on 26 March 1941 as the 1st Air Force, 2nd Air Force, 3rd Air Force, & 4th Air Force,[5] The differing military Aircraft Warning Corps (cf. the civilian Aircraft Warning Service) was a USAAF organization for air defense warning with information centers that networked an area's "Army Radar Stations" which communicated radar tracks by telephone. The AWC information centers also integrated visual reports processed by Ground Observer Corps filter centers. AWC information centers notified air defense command posts of the "4 continental air forces" for deploying interceptor aircraft which used command guidance for ground-controlled interception. The USAAF "inactivated the aircraft warning network in April 1944",[6]:38 e.g., the Mount Tamalpais Radar Site in California[7] (the landform was later used by ADC.)
Continental Air Forces
Continental Air Forces (CAF) was a command "activated 12 December 1944"[8] with the 4 "Air Forces" as components to consolidate the CONUS air defense mission under one command[9] (AAF Regulation 20-1 later specified the post-war CAF mission.)[10] For aircraft warning, in 1945 CAF had recommended "research and development be undertaken on radar and allied equipment for an air defense system [for] the future threat", e.g., a "radar [with] range of 1,000 miles, [to detect] at an altitude of 200 miles, and at a speed of 1,000 miles per hour";[11] but the Hq AAF responded that "until the kind of defense needed to counter future attacks could be determined, AC&W planning would have to be restricted to the use of available radar sets".[12] CAF's January 1946 Radar Defense Report for Continental United States recommended military characteristics for a post-war Air Defense System "based upon such advanced equipment,"[13] and the HQ AAF Plans reminded "the command that radar defense planning had to be based on the available equipment."[14]
Planning to reorganize for a separate USAF had begun by the fall 1945 Simpson Board to plan "the reorganization of the Army and the Air Force".[15] In January 1946 "Generals Eisenhower and Spaatz agreed on an Air Force organization [to have] the Strategic Air Command, the Air Defense Command, the Tactical Air Command, the Air Transport Command and the supporting Air Technical Service Command, Air Training Command, the Air University, and the Air Force Center."[15]
The "Continental Air Forces reorganization"[16] began in 1945 when Muroc Field transferred to ATSC (16 October), and Moody Field transferred to AAF Training Command (1 November)--ground radar and interceptor plans at CAF HQ "in expectation that it would become" Air Defense Command were prepared for the transfer.[9] CAF military installations that became ADC bases included :

Air Defense Command
Air Defense Command was activated on 21 March 1946 with the former CAF Fourth Air Force, the tbd's Tenth Air Force, and the tbd's Fourteenth Air Force (Second Air Force was reactivated and added on 6 June.) In December 1946 "Development of Radar Equipment for Detecting and Countering Missiles of the German A-4 type" was planned[17] (part of Signal Corps' Project 414A contracted to Bell Laboratories in 1945).[6]:207 The Distant Early Warning Line was "first conceived—and rejected—in 1946".[6]:2
A 1947 proposal for 411 radar stations and 18 control centers costing $600 million[18] was the Project Supremacy plan for a postwar Radar Fence that was rejected by Air Defense Command since "no provision was made in it for the Alaska to Greenland net with flanks guarded by aircraft and picket ships [required] for 3 to 6 hours of warning time",[6]:129 and "Congress failed to act on legislation required to support the proposed system".[6] (In the spring and summer of 1947, 3 ADC AC&W plans had gone unfunded.[19]:53) By 1948 there were only 5 AC&W stations, including the Twin Lights station in NJ that opened in June and Montauk NY "Air Warning Station #3 (July 5)[20]--cf. SAC radar stations, e.g., at Dallas & Denver Bomb Plots.[21]
ADC became a subordinate operational command of Continental Air Command on 1 December 1948 and on 27 June 1950, United States air defense systems began 24-hour operations two days after the start of the Korean War.[22] By the time ADC was inactivated on 1 July 1950, ADC had deployed the Lashup Radar Network with existing radars at 43 sites. In addition, 36 Air National Guard fighter units were called to active duty for the mission.[18]
Reinstatement
ADC was reinstated as a major command on 1 January 1951 at Mitchel Air Force Base, New York, moved to Ent Air Force Base in Colorado Springs on 8 January 1951, and received 21 former ConAC active-duty fighter squadrons (37 additional Air National Guard fighter squadrons if called to active duty). ADC was also assigned the 25th, 26th 27th and 28th Air Divisions (Defense)[22] ADC completed the Priority Permanent System network for Aircraft Warning and Control (ground-controlled interception) in 1952. Gaps were filled by additional Federal Aviation Administration (FAA) radar stations and the Ground Observation Corps (disbanded 1959).[18] In May 1954, ADC moved their 1951 command center from a former hallway/latrine area of the Ent AFB headquarters building into a "much improved 15,000-square-foot concrete block" building[1]:261 with "main battle control center".[23]
During the mid-1950s, the nation's defense planners devised the idea of extending the wall of powerful land-based radar seaward with Airborne early warning and control units. This was done by equipping two wings of Lockheed RC-121 Warning Star aircraft, the 551st Airborne Early Warning and Control Wing, based at Otis Air Force Base, Massachusetts, and the 552nd AEWCW, based at McClellan Air Force Base, California, one wing stationed on each coast. The RC-121s, EC-121s and Texas Towers, it was believed, would contribute to extending contiguous east-coast radar coverage some 300 to 500 miles seaward. In terms of the air threat of the 1950s, this meant a gain of at least 30 extra minutes warning time of an oncoming bomber attack.[24] ADC's Operation Tail Wind on 11–12 July tested its augmentation plan that required Air Training Command interceptors participate in an air defense emergency. A total of seven ATC bases actively participated in the exercise, deploying aircraft and aircrews and supporting the ADC radar net.[25] As the USAF prepared to deploy the Tactical Air Command E-3 Sentry in the later 1970s, active-duty units were phased out EC-121 operations by the end of 1975. All remaining EC-121s were transferred to the Air Force Reserve, which formed the 79th AEWCS at Homestead Air Force Base, Florida in early 1976. The active duty force continued to provide personnel to operate the EC-121s on a 24-hour basis, assigning Detachment 1, 20th Air Defense Squadron to Homestead AFB as associate active duty crews to fly the Reserve-owned aircraft. Besides monitoring Cuban waters, these last Warning Stars also operated from NAS Keflavik, Iceland. Final EC-121 operations ended in September 1978.
Interceptor Aircraft
ADC had four day-type fighter squadrons (FDS) in 1946, and the ADC interceptor force grew to ninety-three (93) active Air Force fighter interceptor squadrons, seventy-six (76) Air National Guard fighter interceptor squadrons, several Naval fighter squadrons, USAF and USN airborne early warning squadrons, radar squadrons, training squadrons and numerous support units that have played important roles in our nation's defense.[22]
The first ADC interceptor, the P-61 Black Widow did not have the capabilities to engage the Soviet Tu-4 bomber. Its successor, the F-82 Twin Mustang, was even more disappointing. It took a long time to get into production and did not perform well in inclement weather.[26][27]
The early jet fighters, such as the F-80 Shooting Star and F-84 Thunderjet, lacked all-weather capability and were deemed useless for air defense purposes. Much hope was placed on two jet-powered interceptors, the XP-87 Blackhawk and the XP-89 Scorpion. (Designations changed to XF-87 and XF-89.) They, in their turn, proved to be inadequate. The XF-87 was cancelled and the Scorpion had to undergo extensive redesign.[28][29]
The first-generation jets gave way to all-weather dedicated interceptor jets. The F-94 Starfire was pressed into service as an "interim" interceptor. North American in 1949 pushed an interceptor version of the Sabre, the F-86D. Despite the demands its complexity made upon a single pilot, the F-86D was backed by senior Air Force officials. Some 2,504 would be built and it would in time be the most numerous interceptor in the Air Defense Command fleet, with more than 1,000 in service by the end of 1955[30]
The F-86D was not ideal, however, for its afterburner consumed a great deal of fuel in getting it to altitude, and the pilot was overburdened by cockpit tasks. The F-89D was modified to accept AIM-4 Falcon guided missiles (F-89H) and AIR-2 Genie atomic warhead rockets (F-89J) as armament. The F-86D was modified (F-86L) to include an FDDL SAGE data link that permitted automatic ground control. The F-86L and F-89H became available in 1956, the F-89J in 1957.[30]
The first of the Century Series supersonic interceptors was the F-102A Delta Dagger in 1956, followed by the F-104A Starfighter in 1958. The F-101B Voodoo and F-106 Delta Dart were first received by ADC during the first half of 1959. By 1960, the ADC interceptor force was composed of the F-101, F-104, F-106, and the F-102.[31]
The North American F-108 Rapier was the first proposed successor to the F-106. It was to be capable of Mach 3 performance and was intended to serve as a long-range interceptor that could destroy attacking Soviet bombers over the poles before they could get near US territory. It was also to serve as the escort fighter for the XB-70 Valkyrie Mach-3 strategic bomber, also to be built by North American. The Air Force expected that the first F-108A would be ready for service by early 1963. An order for no less than 480 F-108s was anticipated.
However, by mid-1959, the Air Force was already beginning to experience some doubts about the high cost of the Rapier program. The primary strategic threat from the Soviet Union was now perceived to be its battery of intercontinental ballistic missiles instead of its force of long-range bombers. Against intercontinental ballistic missiles, the F-108A interceptor would be completely useless. In addition, the Air Force was increasingly of the opinion that unmanned intercontinental ballistic missiles could accomplish the mission of the B-70 Valkyrie/F-108 Rapier combination much more effectively and at far lower cost. Consequently, the F-108A project was cancelled in its entirety on 23 September 1959, before any prototypes could be built.
In 1968, ADCOM began the phaseout of the F-101 and F-102 interceptors from active duty units. George W. Bush, later President of the United States, flew the F-102 as part of his Air National Guard service in the late 1960s and early 1970s. The F-106 Delta Dart remained, as it was considered by many as being the finest all-weather interceptor ever built. It was the primary air defense interceptor aircraft for the US Air Force during the 1970s through the early 1980s. It was also was the last dedicated interceptor in U.S. Air Force service to date. It was gradually retired during the 1980s, though the QF-106 drone conversions of the aircraft were used until 1998 as aerial targets under the FSAT program.[32]
Interceptor gunnery training
B-57E Canberra dedicated Air Defense Command target towing aircraft were used for training of F-86D Sabre, F-94C Starfire, and F-89D Scorpion interceptors firing 2.75-inch Mk 4/Mk 40 Folding-Fin Aerial Rockets. Due to the nature of air-to-air weapon training requiring a large amount of air space, only a few locations were available for practice ranges. ADC assigned these aircraft to bases close to these large, restricted areas, and fighter-interceptor squadrons deployed to these bases for this type of "hot fire" training which took place in these ranges.
The gunnery schools were located at Yuma AFB, Arizona (17th TTS), and later moved to MacDill AFB, Florida where the training continued over the Gulf of Mexico. With the move to Florida, the 3d TTS was formed at George AFB, California which performed training over the Mojave Desert in Southern California. Additional units were located at Biggs AFB, near El Paso, Texas (1st TTS) and the 4756th TTS was located at Tyndall AFB, Florida to support the Fighter Weapons Center located there. ADC also supported overseas training at Johnson AB, Japan (6th TTS). From Johnson AB, B-57Es deployed to Clark AB, Philippines; Andersen AFB, Guam, Naha AB, Okinawa and Itazuke AB, Misawa AB and Yokota AB, all in Japan for training of the interceptor squadrons assigned to those bases. The 6th TTS was inactivated by late 1957 and the Canberra trainers were designated a flight of the 8th Bombardment Squadron at Johnson AB. In Europe, USAFE supported a squadron of B-57E gunnery trainers at Wheelus AB, Libya where European-based interceptors deployed for "live firing" over the vast desert range there.[33]
To provide challenges for interceptors, The B-57Es towed styroforam, bomb-shaped radar reflectant targets. These could be towed at higher altitudes than the high-drag 45' banners but hits could still be scored on them. By 1960, the rocket firing interceptors were giving way to F-102 Delta Dagger interceptors firing heat-seeking AIM-4 Falcon air-to-air missiles. This made the target towing mission of the B-57E obsolete, and the B-57Es were adapted to electronic countermeasures and faker target aircraft (EB-57E) (see below).[33]
In order to cover combat losses in the Vietnam War caused by two major ground explosions, twelve B-57Es were reconfigured as combat-capable B-57Bs at the Martin factory in late 1965 and were deployed to Southeast Asia for combat bombardment operations. Six other B-57Es were converted to RB-57E "Patricia Lynn" tactical reconnaissance aircraft in 1966 during the Vietnam War, operating from Tan Son Nhut Air Base until 1971.[33]
- Interceptor Missiles (IMs)
- The Bomarc Missile Program delivered the first CIM-10 Bomarc supersonic surface-to-air missile to ADC during September 1959 at Fort Dix's BOMARC Base No. 1 near the missile launch control center on McGuire AFB (groundbreaking for McGuire's Air Defense Direction Center to house the IBM AN/FSQ-7 Combat Direction Central for Bomarc ground-controlled interception had been in 1957.) To ensure probability of kill before bombers could drop their weapons, the AN/FSQ-7 used the Automatic Target and Battery Evaluation (ATABE) to determine which bombers/formations to assign to which manned interceptor base (e.g., using nuclear air-to-air missiles), which to assign to Bomarcs (e.g., with W-40 nuclear warheads) and if available, which to assign to the region's Nike Army Air Defense Command Post (that also had ATABE software for efficiently coordinating fire from multiple Hercules missile batteries.) Bomarc missiles bases were along the east and west coasts of North America and the central areas of the continent (e.g., Suffolk County Missile Annex was on Long Island, New York.) The supersonic Bomarc missiles were the first long-range anti-aircraft missiles in the world, and the longer range BOMARC B models required less time after erected until they could be launched.[34]
Defense Systems Evaluation
"Faker", or simulated target aircraft flew mock penetrations into air defense sectors to exercise GDI stations, Air Defense Direction Centers, and interceptor squadrons. Initially using modified B-25 Mitchell and B-29 Superfortress bombers, the aircraft would fly attack profile missions at unexpected, random times and attempt to evade coverage by flying at low altitudes and randomly flying in different directions to confuse interceptors. The aircraft were modified to carry electronic countermeasures (ECM) gear to attempt to confuse radar operators. In 1957, the propeller-driven aircraft were phased out and replaced by Martin B-57 medium bombers which were being phased out of Tactical Air Command. Initially RB-57As from reconnaissance units were modified to have their former camera bays refitted to carry out the latest ECM systems to confuse the defenders. Wing racks, originally designed for bombs, now carried chaff dispensers and the navigator position was replaced with an Electronic Warfare Officer (EWO). The modified B-57s were designated as EB-57 (E for special electronic installation).[33]
Considerable realism would be generated into these simulated aggressor attack missions being flown by the B-57 crews. Often several EB-57s were used to form separate tracks and provide a coordinated jamming attack to complicate the testing. When inside the range of the GCI radar, and in anticipation of interception, chaff was dispensed to confuse the defense force and electronic pulses to jam radar signals were turned on. It was up to the defending interceptors and GCI stations to sort out the correct interception.[33]
Units operating these specially equipped aircraft were designated Defense Systems Evaluation Squadrons (DSES). The 4713th Defense Systems Evaluation Squadron was stationed for training in the Northeast. The 4713th also deployed frequently to USAFE in West Germany for training of NATO forces. The other was the 4677th Defense Systems Evaluation Squadron, which concentrated on Fighter Interceptor Squadron training for units in the Western United States. In 1974, the 4713th DSES was inactivated and its EB-57s were divided between two Air National Guard units and the 4677th DSES was redesignated as the 17th Defense Systems Evaluation Squadron. This unit was inactivated in July 1979 and was the last to fly B-57s in the active duty USAF. It shared the Defense Systems Evaluation mission with the Kansas and Vermont Air National Guard. Defense Systems Evaluation operations were also carried out by the 6091st Reconnaissance Squadron, Yokota AB, Japan; later the 556th Reconnaissance Squadron and moved to Kadena AB, Okinawa. EB-57s were also deployed to Alaskan Air Command, Elmendorf AFB, Alaska, frequently.[33]
The 134th Defense Systems Evaluation Squadron, Vermont Air National Guard, retired its last EB-57 in 1983, and the operational use of the B-57 Canberra ended.[33]
Continental defense
From 1 September 1954 until 1975, ADC was a component of the unified Continental Air Defense Command (CONAD) along with the Army's ARAACOM (1957 ARADCOM) and until 1965, the Navy's NAVFORCONAD. The USAF as the executive CONAD agent initially used ADC's:
- commander as CINCONAD,
- headquarters staff in ADC's HQ building for the unified command staff, and
- new blockhouse for the unified command center
ADC'a Permanent System radar stations were used for CONAD target data, along with Navy picket ships (Atlantic and Pacific Barrier until 1965) and Army Project Nike "target acquisition radars". A CONAD reorganization that started in 1956 created a separate multi-service CONAD headquarters staff (with Air Force Element), separated command of ADC from CINCONAD (LGen Atkinson became ADC commander on 22 September), and in 1957 added Alaskan Air Command and Northeast Air Command components to ADC[23]—former NEAC installations in a smaller "Canadian Northeast Area" were transferred under control of Royal Canadian Air Force ADC[36] (e.g., the Hall Beach "FOX.MAIN" DEW Line station constructed 1955-1957[37]--cf. Canada's Hopedale stations of the 1954 Pinetree Line and 1957 Mid-Canada Line.)
ADC's 64th AD military personnel were assigned to main stations of the 1957 DEW Line and annually inspected auxiliary/intermediate DEW stations maintained by the "DEW M&O Contractor[36]" (the White Alice Communications System linked ADC aircraft with DEW Line radars.) On 1 March 1957 CONAD reduced the number of ADC interceptor squadrons on alert for the Air Defense Identification Zone.[38] "At the end of 1957, ADC operated 182 radar stations…32 had been added during the last half of the year as low-altitude, unmanned gap-filler radars. The total consisted of 47 gap-filler stations, 75 Permanent System radars, 39 semimobile radars, 19 Pinetree stations,…1 Lashup[-era] radar and a single Texas Tower".[1]:223 ADC subsequently became a CONAD component of NORAD, for which the international agreement was signed on 12 May 1958 (RCAF officers agreed NORAD's "primary purpose would be…early warning and defense for SAC's retaliatory forces.")[1]:252
- SAGE
- The Semi-Automatic Ground Environment (SAGE) for radar operators was installed at ADC's general surveillance stations by deploying CDTS electronics. Implementation of the SAGE Geographic Reorganization Plan of 25 July 1958 activated new ADC military installations, e.g., GATR stations for vectoring manned interceptors as well as BOMARC missile launch complexes with nearby GAT Facilities. On 20 December 1958 NORAD approved the "USAF ADC Plan" which included 10 Super Combat Centers (SCCs) in underground bunkers to replace 5 above-ground Combat Centers remaining to be built.[39] Modification of FAA radars to the ARSR-1A configuration (Amplitron, "antenna gear box modification", etc.) were to be complete by November 1960 (e.g., at the Fort Heath radar station)[40] and all 3 Texas Towers were in-service by April 1959 with ADC detachments/radars on offshore platforms near the New England coast, and the Continental Air Defense Integration North schedule for gap-filler radars included those for "P-20F, London, Ontario; C-4-C, Brampton, Ontario; C-5-C, Mt Carleton, New Brunswick; and C-6-D, Les Etroits. Quebec"—in the spring of 1959, ADC requested the Air Defense Systems Integration Division to study accelerating the scheduled 1962 deployment of those 4 sites.[39] After the planned SCCs were cancelled in 1960, the SAGE System was augmented by the "pre-SAGE semiautomatic intercept system" for Backup Interceptor Control as at North Bend AFS in February 1962 (BUIC II first at North Truro AFS in 1966.)
By 30 June 1958, the Zone of the Interior (ZI) facility for anti-ICBM processing that was planned for ADC to coordinate at Ent AFB the ABM missile fire was considered "the heart of the entire [planned] ballistic missile defense system[40] (conceived to have Nike Zeus[41] and Wizard missiles.) On 19 October 1959, HQ USAF assigned ADC the "planning responsibility" for eventual operations of the Missile Defense Alarm System to detect ICBM launches with infrared sensors on space vehicles.[42]
Missile warning and space surveillance
ADC's BMEWS Central Computer and Display Facility was built as an austere network center (instead of for coordinating anti-ICBM fire) which "at midnight on 30 September I960…achieved initial operational capability" (IOC). On 1 July 1961 for space surveillance, ADC took over the Laredo Test Site and the Trinidad Air Station from Rome Air Development Center.[4] The "1st Aero" cadre at the Hanscom AFB NSSCC moved 496L System operations in July 1961 to Ent's "SPADATS Center"[15] in the annex of building P4. Operational BMEWS control of the Thule Site J RCA AN/FPS-50 Radar Sets transferred from RCA to ADC on January 5, 1962 (the 12MWS activated in 1967.) By 30 June 1962, integration of ADC's BMEWS CC&DF and the SPADATS Center was completed at Ent AFB,[43] and the Air Forces Iceland transferred from Military Air Transport Service to ADC on 1 July 1962.
The 9th ADD established the temporary 1962 "Cuban Missile Early Warning System" for the missile crisis. Responsibility for a USAFSS squadron's AN/FPS-17 radar station in Turkey for missile test monitoring transferred to ADC on 1 July 1963, the same date the site's AN/FPS-79 achieved IOC.[44] By January 1963, ADC's Detachment 3 of the 9th Aerospace Defense Division (9th ADD) was providing space surveillance data from the Moorestown BMEWS station "to a Spacetrack Analysis Center at Colorado Springs."[45] On 31 December 1965, Forward Scatter Over-the-Horizon network data from the 440L Data Reduction Center was being received by ADC for missile warning, and a NORAD plan for 1 April 1966 was for ADC to "reorganize its remaining 26th, 28th, 29th, and 73d Air Divisions into four air forces."[46]
The 1966 20th Surveillance Squadron began ADC's phased array operations with the Eglin AFB Site C-6 Project Space Track radar (the Eglin phased array's IOC was in 1969, and the North Dakota CMEWS "began passing" PARCS phased array data to NORAD in 1977 after being "modified for the ADCOM mission".[2]
After claiming in March 1958 that "the Army's ZEUS did not have the growth potential to handle possible enemy evasion decoy and countermeasure tactics", the USAF similarly identified by early 1959 that its planned Wizard missile was "not cost effective" against ICBM warheads.[47]—the Army Zeus deployed successors against ICBMs (SAFEGUARD System, 1975-6) and space vehicles (Johnston Atoll, 1962-75). After tests of the 1959 High Virgo (at Explorer 5), 1959 Bold Orion (Explorer 6), and 1963 Project 505 (Nike Zeus) anti-satellite tests (the latter's nuclear burst destroyed a satellite), the Air Force Systems Command ASM-135 ASAT collided with a satellite in 1984.
Consolidated C3
ADC's Consolidated Command. Control and Communications Program, FY 1965-1972[46] was an outgrowth of a 196x "ADC-NORAD PAGE Study" for replacing SAGE/BUIC with a Primary Automated Ground Environment (PAGE) .[48] The program with a Joint DOD/FAA National Airspace System (NAS)[49] resulted with DOD/FAA agreements for a common aircraft surveillance system,[50] with the FAA "to automate its new National Airspace System (NAS) centers".[46] ADC estimated its portion "would cost about $6 million, with annual operating, maintenance, and communication costs about $3.5 million"[50] ("the first BUIC III was set to begin in April 1967 at Z-50, Saratoga Springs".)[48]
As the space mission grew the command changed its name, effective 15 January 1968, to Aerospace Defense Command, or ADCOM. Under ADCOM, emphasis went to systems for ballistic missile detection and warning and space surveillance, and the atmospheric detection and warning system, which had been in an almost continuous state of expansion and improvement since the 1950s, went into decline.[22]
BOMARC, for example, was dropped from the weapons inventory, and the F-101 and F-102 passed from the regular Air Force inventory into the National Guard. To save funds and manpower, drastic reductions were made in the number of long range radar stations, the number of interceptor squadrons, and in the organizational structure. By 1968 the DOD was making plans to phase down the current air defense system and transition to a new system which included an Airborne Warning and Control System (AWACS), Over-the-Horizon Backscatter (OTH-B) radar, and an improved F-106 interceptor aircraft.[22]
The changing emphasis in the threat away from the manned bomber and to the ballistic missile brought reorganization and reduction in aeropace defense resources and personnel and almost continuous turmoil in the management structure. The headquarters of the Continental Air Defense Command (CONAD) and ADC were combined on 1 July 1973. Six months later in February 1973, ADC was reduced to 20 fighter squadrons and a complete phaseout of air defense missile batteries.[22]
Continental Air Command was disestablished on 1 July 1975 and Aerospace Defense Command became a specified command by direction of the JCS. Reductions and reorganizations continued into the last half of the 1970s, but while some consideration was given to closing down the major command headquarters altogether and redistributing field resources to other commands, such a move lacked support in the Air Staff.[22]
Inactivation
In early 1977 strong Congressional pressure to reduce management "overhead", and the personal conviction of the USAF Chief of Staff that substantial savings could be realized without a reduction in operational capability, moved the final "reorganization" of ADCOM to center stage. Two years of planning followed, but by late 1979 the Air Force was ready to carry it through. It was conducted in two phases:[22]
- On 1 October 1979 ADCOM atmospheric defense resources (interceptors, warning radars, and associated bases and personnel) were transferred to Tactical Air Command, being placed under Air Defense, Tactical Air Command (ADTAC). which was established compatible to a Numbered Air Force under TAC. With this move many Air National Guard units that had an air defense mission also came under the control of TAC. ADTAC was headquartered at North American Aerospace Defense Command, Ent AFB Colorado. In essence, Tactical Air Command became the old Continental Air Command. On the same date, electronic assets went to the Air Force Communications Service (AFCS).[22]
- On 1 December 1979 missile warning and space surveillance assets were transferred to Strategic Air Command. On the same date the Aerospace Defense Center, a Direct Reporting Unit, was established from the remnants of ADCOM headquarters[22]
ADCOM, as a specified command, continued as the United States component of NORAD, but the major air command was inactivated on 31 March 1980. The unit designation of the MAJCOM reverted to the control of the Department of the Air Force.[22]

In November 1945, General Dwight D. Eisenhower became Army Chief of Staff… One of General Eisenhower’s first actions was to appoint a board of officers, headed by Lieutenant General W. H. Simpson, to prepare a definitive plan for the reorganization of the Army and the Air Force that could be effected without enabling legislation and would provide for the separation of the Air Force from the Army. … In July of 1961, the National Space Surveillance and Control Center (NSSCC) was discontinued as the new SPADATS Center became operational at Ent AFB, Colorado. Officially, this marked the beginning of aerospace operations by CINCNORAD.

HQ USAF decided effective 20 October to assign ATC responsibility for supporting Air Defense Command (ADC). All three of ATC's interceptor training bases had air defense commitments. Moody maintained two combat-ready aircraft and crews on five-minute active air alert as ADC augmentation forces. Tyndall had a requirement to deploy 16 combat-ready F-86D aircraft and to maintain 16 others in a 4-hour readiness state in the event of an emergency. Peirin maintained an ADC defense squadron manned with ATC aircraft and instructor pilots as part of the active air alert force.

During the 1 July-31 July period, it would remain the responsibility of WEC [but] operational limitations of the sectors were numerous: landline tie-ins to CONAD's combat operations center were not installed; the rearward UHF and VHF scatter communications systems still required considerable testing … communications circuits to the AMIS facilities had not been connected to their AR'm centers, nor were the AMIS facilities in the AR'm centers ready; the supply depot being constructed at Frobisher had not been completed … In June 1957, it was reported that all military personnel were in-place. On 12 June, some 675 people were on the line with 705·expected to be in-place by 1 July 1957. '!he personnel were receiving OJT with the assistance or WEC. …the efficiency or the "radicians" was expected to be poor until they had gained surficient experience and training. … CONAD was also opposed to the identification procedures outlined in the USAF-RCAF Operations Plan on 1 June 1956. … DEWPO (Distant Early Warning Project Office) … ADC also succeeded NEAC in the responsibilities it held tor supporting and running the DEW line stations in eastern Canada and Greenland.5
