Editing CIM-10 Bomarc (section)

===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 propellant]]s (hydrazine and nitric acid) were very dangerous to handle, leading to several serious accidents.<ref name="Gibson"/>

As soon as high-thrust [[solid-fuel rocket]]s became a reality in the mid-1950s, the USAF began to develop a new solid-fueled Bomarc variant, the IM-99B Bomarc&nbsp;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 [[SSM-N-9 Regulus II|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 {{convert|700|km|mi|abbr=on|order=flip}}. The terminal homing system was also improved, using the world's first [[Pulse-Doppler radar|pulse Doppler search radar]], the Westinghouse AN/DPN-53.<ref name="ReferenceA"/> All Bomarc&nbsp;Bs were equipped with the W-40 nuclear warhead. In June 1961, the first IM-99B squadron became operational, and Bomarc&nbsp;B quickly replaced most Bomarc&nbsp;A missiles.<ref name="Gibson"/> On 23 March 1961, a Bomarc&nbsp;B successfully intercepted a Regulus&nbsp;II cruise missile flying at {{cvt|100000|ft|m}}, 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.<ref name="Gibson"/>

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 (Florida)|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, [[Aerospace Defense Command|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.<ref name="Gibson"/>
