Michael Hoffman reports in Military Times that five (some say six) nuclear-armed Advanced Cruise Missiles were mistakenly flown on a B-52H bomber from Minot Air Force Base in North Dakota to Barksdale Air Force Base in Louisiana on August 30.

I disclosed in March that the Air Force had decided to retire the Advanced Cruise Missile (ACM), and the Minot incident apparently was part of the dismantlement process of the weapon system.

Article: U.S. Nuclear Stockpile Today and Tomorrow

The latest FAS-NRDC estimate of the U.S. nuclear weapons stockpile has been published in the Bulletin of the Atomic Scientists.

By Hans M. Kristensen

The U.S. nuclear weapons stockpile currently contains an estimated 9,900 nuclear warheads of 15 different versions of nine basic types, according to the latest FAS-NRDC Nuclear Notebook published in the Bulletin of the Atomic Scientists. By 2012, approximately 4,470 of the warheads will have been withdrawn, leaving a stockpile of roughly 5,500 warheads.

The administration insists that the size and breakdown of the stockpile must be kept secret in the interest of national security, but a growing number of lawmakers argue that some stockpile information is not necessary to classify.

The Nuclear Notebook is written by FAS’ Hans M. Kristensen and NRDC’s Robert Norris.
