A new review published in the November/December issue of the Bulletin of the Atomic Scientists shows that the United States stores its nearly 10,000 nuclear warheads at 18 locations in 12 states and six European countries.

The highest concentration of nuclear warheads is at the Strategic Weapons Facility Pacific in Bangor, Washington, which is home to more than 2,300 warheads – probably the most nuclear weapons at any one site in the world. At any given moment, nearly half of these warheads are on board ballistic-missile submarines in the Pacific Ocean.

The 10 U.S. sites that currently host nuclear weapons are: the Strategic Weapons Facility Pacific, Bangor, Washington; Nellis Air Force Base, Nevada; Warren Air Force Base, Wyoming; Kirtland Air Force Base, New Mexico; Malmstrom Air Force Base, Montana; Minot Air Force Base, North Dakota; Pantex Plant, Texas; Barksdale Air Force Base, Louisiana; Whiteman Air Force Base, Missouri; and the Strategic Weapons Facility Atlantic, Kings Bay, Georgia. (See map.)

The U.S. government refuses to disclose where it stores nuclear weapons, but the researchers emphasize that all the locations have been known for years to house nuclear weapons. Safety of nuclear weapons is determined not by knowledge of their location but by the military's physical protection of the facilities and that the weapons cannot be detonated by unauthorized personnel.
