The U.S. Air Force has decided to retire the Advanced Cruise Missile, the most modern and capable nuclear cruise missile in the U.S. arsenal, according to information obtained by the Federation of American Scientists.
The decision affects approximately 400 ACMs (AGM-129A) currently deployed at Minot Air Force Base in North Dakota and Barksdale Air Force Base in Louisiana. Each missile carries a W80-1 warhead with a yield of 5-150 kilotons. The ACM is designed for delivery by B-52H strategic bombers.
FAS analyst Hans Kristensen noticed elimination of funding for the ACM in the Air Force’s FY2008 budget request, and a subsequent email to the Air Force confirmed the decision to retire the weapon system. The Air Force has not announced when the retirement will be completed, but it appears to be within the next year.
