General Dynamics AGM-129A Advanced Cruise Missile The Advanced Cruise Missile (ACM) is an air-to-ground cruise missile developed to provide the U.S. Air Force with a long range, highly survivable, strategic standoff weapon. The ACM uses laser sensor updates to give it high navigation accuracy, and stealth technology gives it a low radar cross section and increased chance to penetrate enemy defenses. The distinctive forward swept wing is an example of the application of stealth technology. Up to 12 ACMs can be carried by a B-52H bomber, allowing the bomber to attack multiple targets without penetrating enemy airspace. Full-scale development of the ACM began in 1983, and the first production missile was delivered in 1987. Production contracts for ACMs were awarded to General Dynamics and McDonnell Douglas. The ACM on display is the 12th full-scale development article built. It was used for numerous captive-carry (unlaunched) test flights with both B-52H and B-1B aircraft at Edwards Air Force Base, Calif. Tests of missile software and systems integration with the carrier aircraft were completed successfully during those flights.
