Located at the Museum of Flight are a large number of static aircraft on display. One of them is a Boeing AGM-86B Air Launch Cruise Missile. A nearby placard highlights the background information on this missile and it reads:
A Standoff Weapon
The Air Launch Cruise Missile (ALCM) is a small, unmanned air vehicle carried by the U.S. Strategic Air Command B-52 and B-1 bombers. The cruise missile is called a "Stand-off weapon" because of its ability to hit a target hundreds of miles away without endangering air crews. The unmanned ALCM can carry a nuclear or high explosive warhead over 1,550 miles (2,494 km).
The ALCM flies low, at treetop level, to avoid detection and enemy air defenses. It is guided by a computer that uses a radar altimeter to match the surrounding terrain with an electronic "map" of the ALCM's pre-planned route.
The Museum's ALCM was built by Boeing in Kent, Washington. During its operational life, it was often loaded onto readied aircraft, but was never used in combat.
