CIM-10 Bomarc. The Boeing CIM-10 Bomarc ("Boeing Michigan Aeronautical Research Center") (IM-99 Weapon System prior to September 1962) was a supersonic ramjet powered long-range surface-to-air missile (SAM) used during the Cold War for the air defense of North America. In addition to being the first operational long-range SAM and the first operational pulse doppler aviation radar, it was the only SAM deployed by the United States Air Force.

Stored horizontally in a launcher shelter with a movable roof, the missile was erected, fired vertically using rocket boosters to high altitude, and then tipped over into a horizontal Mach 2.5 cruise powered by ramjet engines. This lofted trajectory allowed the missile to operate at a maximum range as great as . Controlled from the ground for most of its flight, when it reached the target area it was commanded to begin a dive, activating an onboard active radar homing seeker for terminal guidance. A radar proximity fuse detonated the warhead, either a large conventional explosive or the W40 nuclear warhead.

The Air Force originally planned for a total of 52 sites covering most of the major cities and industrial regions in the US. The United States Army was deploying their own systems at the same time, and the two services fought constantly both in political circles and in the press. Development dragged on, and by the time it was ready for deployment in the late 1950s, the nuclear threat had moved from manned bombers to the intercontinental ballistic missile (ICBM). By this time the Army had successfully deployed the much shorter range Nike Hercules that they claimed filled any possible need through the 1960s, in spite of Air Force claims to the contrary.

As testing continued, the Air Force reduced its plans to sixteen sites, and then again to eight with an additional two sites in Canada. The first US site was declared operational in 1959, but with only a single working missile. Bringing the rest of the missiles into service took years, by which time the system was obsolete. Deactivations began in 1969 and by 1972 all Bomarc sites had been shut down. A small number were used as target drones, and only a few remain on display today.

Design and development

Initial studies
During World War II, the US Army Air Force (USAAF) concluded that existing anti-aircraft guns, only marginally effective against existing generations of propeller-driven aircraft, would not be effective at all against the emerging jet-powered designs. Like the Germans and British before them, they concluded the only successful defence would be to use guided weapons.

As early as 1944 the United States Army started exploring anti-aircraft missiles, examining a variety of concepts. At the time, two basic concepts appeared possible; one would use a short-range rocket that flew directly at the target from below following a course close to the line-of-sight, and the other would fly up to the target's altitude and then tip over and fly horizontally towards the target like a fighter aircraft. As both concepts seemed promising, the Army Air Force was given the task of developing the airplane-like design, while the Army Ordnance Department was given the more ballistic collision-course concept. Official requirements were published in 1945.

Official requirements were published in 1945; Bell Laboratories won the Ordnance contract for a short-range line-of-sight weapon under Project Nike, while a team of players led by Boeing won the contract for a long-range design known as Ground-to-Air Pilotless Aircraft, or GAPA. GAPA moved to the United States Air Force when that branch was formed in 1947. In 1946, the USAAF also started two early research projects into anti-missile systems in Project Thumper (MX-795) and Project Wizard (MX-794).

Bomarc A
Formally organized in 1946 under USAAF project MX-606, by 1950 Boeing had launched more than 100 test rockets in various configurations, all under the designator XSAM-A-1 GAPA. The tests were very promising, and Boeing received a USAF contract in 1949 to develop a production design under project MX-1599.

The MX-1599 missile was to be a ramjet-powered, nuclear-armed long-range surface-to-air missile to defend the Continental United States from high-flying bombers. The Michigan Aerospace Research Center (MARC) was added to the project soon afterward, and this gave the new missile its name Bomarc (for Boeing and MARC). In 1951, the USAF decided to emphasize its point of view that missiles were nothing else than pilotless aircraft by assigning aircraft designators to its missile projects, and anti-aircraft missiles received F-for-Fighter designations. The Bomarc became the F-99.

By this time, the Army's Nike project was progressing well and would enter operational service in 1953. This led the Air Force to begin a lengthy series of attacks on the Army in the press, a common occurrence at the time known as "policy by press release". When the Army released its first official information on Ajax to the press, the Air Force responded by leaking information on BOMARC to Aviation Week, and continued to denigrate Nike in the press over the next few years, in one case showing a graphic of Washington being destroyed by nuclear bombs that Ajax failed to stop.

Tests of the XF-99 test vehicles began in September 1952 and continued through early 1955. The XF-99 tested only the liquid-fueled booster rocket, which would accelerate the missile to ramjet ignition speed. In February 1955, tests of the XF-99A propulsion test vehicles began. These included live ramjets, but still had no guidance system or warhead. The designation YF-99A had been reserved for the operational test vehicles. In August 1955, the USAF discontinued the use of aircraft-like type designators for missiles, and the XF-99A and YF-99A became XIM-99A and YIM-99A, respectively. Originally the USAF had allocated the designation IM-69, but this was changed (possibly at Boeing's request to keep number 99) to IM-99 in October 1955.

By this time, Ajax was widely deployed around the United States and some overseas locations, and the Army was beginning to develop its much more powerful successor, Nike Hercules. Hercules was an existential threat to BOMARC, as its much greater range and nuclear warhead filled many of the roles that BOMARC was designed for. A new round of fighting in the press broke out, capped by an article in The New York Times entitled "Air Force Calls Army Nike Unfit To Guard Nation".

In October 1957, the first YIM-99A production-representative prototype flew with full guidance, and succeeded to pass the target within destructive range. In late 1957, Boeing received the production contract for the IM-99A Bomarc A, and in September 1959, the first IM-99A squadron became operational.

The IM-99A had an operational radius of  and was designed to fly at Mach 2.5–2.8 at a cruising altitude of . It was  long and weighed . Its armament was either a  conventional warhead or a W40 nuclear warhead (7–10 kiloton yield). A liquid-fuel rocket engine boosted the Bomarc to Mach 2, when its Marquardt RJ43-MA-3 ramjet engines, fueled by 80-octane gasoline, would take over for the remainder of the flight. This was the same model of engine used to power the Lockheed X-7, the Lockheed AQM-60 Kingfisher drone used to test air defenses, and the Lockheed D-21 launched from the back of an M-21, although the Bomarc and Kingfisher engines used different materials due to the longer duration of their flights.

Operational units

The operational IM-99A missiles were based horizontally in semi-hardened shelters, nicknamed "coffins". After the launch order, the shelter's roof would slide open, and the missile raised to the vertical. After the missile was supplied with fuel for the booster rocket, it would be launched by the Aerojet General LR59-AJ-13 booster. After sufficient speed was reached, the Marquardt RJ43-MA-3 ramjets would ignite and propel the missile to its cruise speed of Mach 2.8 at an altitude of .

When the Bomarc was within  of the target, its own Westinghouse AN/DPN-34 radar guided the missile to the interception point. The maximum range of the IM-99A was , and it was fitted with either a conventional high-explosive or a 10 kiloton W-40 nuclear fission warhead.

The Bomarc relied on the Semi-Automatic Ground Environment (SAGE), an automated control system used by NORAD for detecting, tracking and intercepting enemy bomber aircraft. SAGE allowed for remote launching of the Bomarc missiles, which were housed in a constant combat-ready basis in individual launch shelters in remote areas. At the height of the program, there were 14 Bomarc sites located in the US and two in Canada.

Bomarc B
The liquid-fuel booster of the Bomarc A had several drawbacks. It took two minutes to fuel before launch, which could be a long time in high-speed intercepts, and its hypergolic propellants (hydrazine and nitric acid) were very dangerous to handle, leading to several serious accidents.

As soon as high-thrust solid-fuel rockets became a reality in the mid-1950s, the USAF began to develop a new solid-fueled Bomarc variant, the IM-99B Bomarc B. It used a Thiokol XM51 booster, and also had improved Marquardt RJ43-MA-7 (and finally the RJ43-MA-11) ramjets. The first IM-99B was launched in May 1959, but problems with the new propulsion system delayed the first fully successful flight until July 1960, when a supersonic MQM-15A Regulus II drone was intercepted. Because the new booster required less space in the missile, more ramjet fuel could be carried, thus increasing the range to . The terminal homing system was also improved, using the world's first pulse Doppler search radar, the Westinghouse AN/DPN-53. All Bomarc Bs were equipped with the W-40 nuclear warhead. In June 1961, the first IM-99B squadron became operational, and Bomarc B quickly replaced most Bomarc A missiles. On 23 March 1961, a Bomarc B successfully intercepted a Regulus II cruise missile flying at , thus achieving the highest interception in the world up to that date.

Boeing built 570 Bomarc missiles between 1957 and 1964, 269 CIM-10A, 301 CIM-10B.

In September 1958 Air Research & Development Command decided to transfer the Bomarc program from its testing at Cape Canaveral Air Force Station to a new facility on Santa Rosa Island, south of Eglin AFB Hurlburt Field on the Gulf of Mexico. To operate the facility and to provide training and operational evaluation in the missile program, Air Defense Command established the 4751st Air Defense Wing (Missile) (4751st ADW) on 15 January 1958. The first launch from Santa Rosa took place on 15 January 1959.

Operational history
In 1955, to support a program which called for 40 squadrons of BOMARC (120 missiles to a squadron for a total of 4,800 missiles), ADC reached a decision on the location of these 40 squadrons and suggested operational dates for each. The sequence was as follows: ... l. McGuire 1/60 2. Suffolk 2/60 3. Otis 3/60 4. Dow 4/60 5. Niagara Falls 1/61 6. Plattsburgh 1/61 7. Kinross 2/61 8. K.I. Sawyer 2/61 9. Langley 2/61 10. Truax 3/61 11. Paine 3/61 12. Portland 3/61 ... At the end of 1958, ADC plans called for construction of the following BOMARC bases in the following order: l. McGuire 2. Suffolk 3. Otis 4. Dow 5. Langley 6. Truax 7. Kinross 8. Duluth 9. Ethan Allen 10. Niagara Falls 11. Paine 12. Adair 13. Travis 14. Vandenberg 15. San Diego 16. Malmstrom 17. Grand Forks 18. Minot 19.  Youngstown 20. Seymour-Johnson 21. Bunker Hill 22. Sioux Falls 23. Charleston 24. McConnell 25. Holloman 26. McCoy 27. Amarillo 28. Barksdale 29. Williams.

United States
The first USAF operational Bomarc squadron was the 46th Air Defense Missile Squadron (ADMS), organized on 1 January 1959 and activated on 25 March. The 46th ADMS was assigned to the New York Air Defense Sector at McGuire Air Force Base, New Jersey. The training program, under the 4751st Air Defense Wing used technicians acting as instructors and was established for a four-month duration. Training included missile maintenance; SAGE operations and launch procedures, including the launch of an unarmed missile at Eglin. In September 1959 the squadron assembled at their permanent station, the Bomarc site near McGuire AFB, and trained for operational readiness. The first Bomarc-A were used at McGuire on 19 September 1959 with Kincheloe AFB getting the first operational IM-99Bs. While several of the squadrons replicated earlier fighter interceptor unit numbers, they were all new organizations with no previous historical counterpart.

ADC's initial plans called for some 52 Bomarc sites around the United States with 120 missiles each but as defense budgets decreased during the 1950s the number of sites dropped substantially. Ongoing development and reliability problems didn't help, nor did Congressional debate over the missile's usefulness and necessity. In June 1959, the Air Force authorized 16 Bomarc sites with 56 missiles each; the initial five would get the IM-99A with the remainder getting the IM-99B. However, in March 1960, HQ USAF cut deployment to eight sites in the United States and two in Canada.

Bomarc incident

Within a year of operations, a Bomarc A with a nuclear warhead caught fire at McGuire AFB on 7 June 1960 after its on-board helium tank exploded. While the missile's explosives did not detonate, the heat melted the warhead and released plutonium, which the fire crews spread. The Air Force and the Atomic Energy Commission cleaned up the site and covered it with concrete. This was the only major incident involving the weapon system. The site remained in operation for several years following the fire. Since its closure in 1972, the area has remained off limits, primarily due to low levels of plutonium contamination. Between 2002 and 2004, 21,998 cubic yards of contaminated debris and soils were shipped to what was then known as Envirocare, located in Utah.

Modification and deactivation
In 1962, the US Air Force started using modified A-models as drones; following the October 1962 tri-service redesignation of aircraft and weapons systems they became CQM-10As. Otherwise the air defense missile squadrons maintained alert while making regular trips to Santa Rosa Island for training and firing practice. After the inactivation of the 4751st ADW(M) on 1 July 1962 and transfer of Hurlburt to Tactical Air Command for air commando operations the 4751st Air Defense Squadron (Missile) remained at Hurlburt and Santa Rosa Island for training purposes.

In 1964, the liquid-fueled Bomarc-A sites and squadrons began to be deactivated. The sites at Dow and Suffolk County closed first. The remainder continued to be operational for several more years while the government started dismantling the air defense missile network. Niagara Falls was the first BOMARC B installation to close, in December 1969; the others remained on alert through 1972. In April 1972, the last Bomarc B in U.S. Air Force service was retired at McGuire and the 46th ADMS inactivated and the base was deactivated.

In the era of the intercontinental ballistic missiles the Bomarc, designed to intercept relatively slow manned bombers, had become a useless asset. The remaining Bomarc missiles were used by all armed services as high-speed target drones for tests of other air-defense missiles. The Bomarc A and Bomarc B targets were designated as CQM-10A and CQM-10B, respectively.

Following the accident, the McGuire complex has never been sold or converted to other uses and remains in Air Force ownership, making it the most intact site of the eight in the US. It has been nominated to the National Register of Historic Sites. Although a number of IM-99/CIM-10 Bomarcs have been placed on public display, because of concerns about the possible environmental hazards of the thoriated magnesium structure of the airframe several have been removed from public view.

Russ Sneddon, director of the Air Force Armament Museum, Eglin Air Force Base, Florida provided information about missing CIM-10 exhibit airframe serial 59–2016, one of the museum's original artifacts from its founding in 1975 and donated by the 4751st Air Defense Squadron at Hurlburt Field, Eglin Auxiliary Field 9, Eglin AFB. As of December 2006, the suspect missile was stored in a secure compound behind the Armaments Museum. In December 2010, the airframe was still on premises, but partly dismantled.

Canada
The Bomarc Missile Program was highly controversial in Canada. The Progressive Conservative government of Prime Minister John Diefenbaker initially agreed to deploy the missiles, and shortly thereafter controversially scrapped the Avro Arrow, a supersonic manned interceptor aircraft, arguing that the missile program made the Arrow unnecessary.

Initially, it was unclear whether the missiles would be equipped with nuclear warheads. By 1960 it became known that the missiles were to have a nuclear payload, and a debate ensued about whether Canada should accept nuclear weapons. Ultimately, the Diefenbaker government decided that the Bomarcs should not be equipped with nuclear warheads. The dispute split the Diefenbaker Cabinet, and led to the collapse of the government in 1963. The Official Opposition and Liberal Party leader Lester B. Pearson originally was against nuclear missiles, but reversed his personal position and argued in favour of accepting nuclear warheads. He won the 1963 election, largely on the basis of this issue, and his new Liberal government proceeded to accept nuclear-armed Bomarcs, with the first being deployed on 31 December 1963. When the nuclear warheads were deployed, Pearson's wife, Maryon, resigned her honorary membership in the anti-nuclear weapons group, Voice of Women.

Canadian operational deployment of the Bomarc involved the formation of two specialized Surface/Air Missile squadrons. The first to begin operations was No. 446 SAM Squadron at RCAF Station North Bay, which was the command and control center for both squadrons. With construction of the compound and related facilities completed in 1961, the squadron received its Bomarcs in 1961, without nuclear warheads. The squadron became fully operational from 31 December 1963, when the nuclear warheads arrived, until disbanding on 31 March 1972. All the warheads were stored separately and under control of Detachment 1 of the USAF 425th Munitions Maintenance Squadron at Stewart Air Force Base. During operational service, the Bomarcs were maintained on stand-by, on a 24-hour basis, but were never fired, although the squadron test-fired the missiles at Eglin AFB, Florida on annual winter retreats.

No. 447 SAM Squadron operating out of RCAF Station La Macaza, Quebec, was activated on 15 September 1962 although warheads were not delivered until late 1963. The squadron followed the same operational procedures as No. 446, its sister squadron. With the passage of time the operational capability of the 1950s-era Bomarc system no longer met modern requirements; the Department of National Defence deemed that the Bomarc missile defense was no longer a viable system, and ordered both squadrons to be stood down in 1972. The bunkers and ancillary facilities remain at both former sites.

Impact on popular music
The Bomarc missile captured the imagination of the American and Canadian popular music industry, giving rise to a pop music group, the Bomarcs (composed mainly of servicemen stationed on a Florida radar site that tracked Bomarcs), a record label, Bomarc Records, and a moderately successful Canadian pop group, The Beau Marks.
