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 By 2012, approximately 4,470 of the warheads will have been withdrawn, leaving a stockpile of roughly 5,500 warheads.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.
