The Boeing CIM-10 Bomarc (IM-99 Weapon System prior to September 1962) was a supersonic ramjet powered interceptor for Cold War air defense of North America which, in addition to being the first long-range anti-aircraft missile (cf. proposed WIZARD predecessor), was the only SAM deployed by the United States Air Force. It used the same Marquardt RJ43 as the Lockheed X-7 hypersonic prototype and the Lockheed AQM-60 drone.
