The Boeing AGM-86 ALCM (AGM-86B and AGM-86C) is an Americansubsonicair-launchedcruise missile (ALCM) built by Boeing Company and operated by the United States Air Force. The missiles were developed to increase the effectiveness and survivability of Boeing B-52H Stratofortress bombers. In combination, they dilute an enemy's forces and complicate defense of its territory. The ALCM is being replaced in the nuclear role by the AGM-129 ACM, with most ALCMs being converted to carry conventional warheads.
