Successful test of Boeing AGM 86D CALCM
30 November 2001
The US Air Force recently flight-tested the new AGM-86D Conventional Air-Launched Cruise Missile (CALCM) at White Sands Missile Range in New Mexico. The missile was launched from a US Air Force B-52 bomber and flew a pre-planned flight path to its target — a hardened, buried target complex, which the warhead penetrated prior to detonation.
Boeing is under contract to convert Air Launched Cruise Missiles (ALCM) to a CALCM variant designated as AGM-86D.
"The AGM-86D will be able to destroy buried or reinforced targets from standoff ranges of hundreds of miles," said Carl Avila, Boeing ALCM/CALCM programme manager. "While the penetrating warhead provides the warfighter with a critical new tool, the key enabling technology is the precision accuracy upgrade — first fielded in the Block 1A configuration — that puts the CALCM within meters of the target."
The AGM-86D uses an advanced unitary penetrating warhead and precision accuracy guidance to hold a portion of the hard and deeply buried target set at risk. Previous conversions have been for the AGM-86C CALCM, which has a 3,000 pound-class blast fragmentation warhead. CALCM has become the Air Force's long-range standoff weapon of choice, principally because of its unparalleled ability to deliver very large warheads with exceptional accuracy over distances in excess of 600 miles.
The conversion process includes a total disassembly of the ALCMs — some of which have been in storage for several years — refurbishment or replacement of nearly every part, overhaul of the engine and other hardware, structural modification of the airframe, then reassembly with modified avionics and a new conventional warhead.
CALCM is the only air-launched, conventionally armed, long-range standoff missile deployed in the Air Force inventory today. Coupled with long-range bombers and air-refueling aircraft, the CALCM missile provides the Air Force a highly responsive capability to launch very accurate conventional attacks against targets located nearly anywhere in the world, without the support of bases located outside the continental United States.
