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

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 By 2012, approximately 4,470 of the warheads will have been withdrawn, leaving a stockpile of roughly 5,500 warheads.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

China is NOT a nuclear “peer” of the United States, as some contend.
China’s total number of approximately 600 warheads constitutes only a small portion of the United States’ estimated stockpile of 3,700 warheads.
