Estimated Nuclear Weapons Locations 2009
|Some 23,300 nuclear weapons are stored at 111 locations around the world (click for map)
By Hans M. Kristensen
The world’s approximately 23,300 nuclear weapons are stored at an estimated 111 locations in 14 countries, according to an overview produced by FAS and NRDC.
Nearly half of the weapons are operationally deployed with delivery systems capable of launching on short notice.
The overview is published in the Bulletin of the Atomic Scientists and includes the July 2009 START memorandum of understanding data. A previous version was included in the annual report from the International Panel of Fissile Materials published last month.

Russia has an estimated 48 permanent nuclear weapon storage sites, of which more than half are on bases for operational forces. There are approximately 19 storage sites, of which about half are national-level storage facilities. In addition, a significant number of temporary storage sites occasionally store nuclear weapons in transit between facilities.
This is a significant consolidation from the estimated 90 Russian sites ten years ago, and more than 500 sites before 1991.
Many of the Russian sites are in close proximity to each other and large populated areas. One example is the Saratov area where the city is surrounded by a missile division, a strategic bomber base, and a national-level storage site with probably well over 1,000 nuclear warheads combined (Figure 2).
The United States stores its nuclear weapons at 21 locations in 13 states and five European countries. This is a consolidation from the estimated 24 sites ten year ago, 50 at the end of the Cold War, and 164 in 1985 (see Figure 3).
|Approximately 50 B61 nuclear bombs inside an igloo at what might be Nellis Air Force Base in Nevada. Seventy-five igloos at Nellis store “one of the largest stockpile in the free world,” according to the U.S. Air Force, one of four central storage sites in the United States.
Europe has about the same number of nuclear weapon storage locations as the Continental United States, with weapons scattered across seven countries. This includes seven sites in France and four in Britain. Five non-nuclear NATO countries (Belgium, Germany, Italy, the Netherlands, and Turkey) still host U.S. nuclear weapons first deployed there during the Cold War.
We estimate that China has 8-14 facilities associated with nuclear weapons, most likely closer to the lower number, near bases with units that operate nuclear missiles or aircraft. None of the weapons are believed to be fully operational but stored separate from delivery vehicles at sites controlled by the Central Military Commission.
Is There a Nuclear Weapons Storage Site on Hainan Island?
|Where does China store nuclear warheads for its ballistic missile submarines? The naval base near Julin on Hainan Island has extensive underground facilities. An alternative to the base itself could potentially be a facility elsewhere on the island, such as Foluo Air Base where construction of an underground facility began five years before the first SSBN arrived at Hainan. Or are the weapons stored on the mainland? Click image to enlarge.|
Israel probably has about four nuclear sites, whereas the nuclear storage facilities in India and Pakistan are – despite many rumors – largely undetermined. All three countries are thought to store warheads separate from delivery vehicles.
Despite two nuclear tests and many rumors, we are unaware of publicly available evidence that North Korea has operationalized its nuclear weapons capability.
Warhead concentrations vary greatly from country to country. With 13,000 warheads at 48 sites, Russian stores an average of 270 warheads at each location. The U.S. concentration is much higher with an average of 450 warheads at each location. These are averages, however, and in reality the distribution is thought to be much more uneven with some sites only storing tens of warheads.
Finally, a word of caution is in order: estimates such as these obviously come with a great deal of uncertainty, as we don’t have access to classified intelligence estimates. Based on publicly available information and our own assumptions we have nonetheless produced a best estimate that we hope will assist the public debate. Comments and suggestions are encouraged so we can adjust the overview in the future.
