There are currently five nations considered to be "nuclear weapons nations", an internationally recognized status conferred by the Nuclear Non-Proliferation Treaty. In order of acquisition of nuclear weapons these are: The United States of America, Russia, The United Kingdom, France, and China. Since the nuclear tests conducted by India and Pakistan, both nations have publicly declared themselves to be in possession of a nuclear arsenal, but this status is not formally recognized by international bodies; neither of the two countries have signed the Nuclear Non-Proliferation Treaty.

Declared nuclear states in order of number of deployed weapons

The following is a list of nations that have admitted the possession of nuclear weapons, and the approximate number of warheads under their control. This list is informally known in global politics as the "Nuclear Club".

From a high of 65,000 weapons in 1985, there were about 40,000 nuclear weapons in the world in 2002.

Suspected nuclear states

Countries believed to have or sometimes suspected of having at least one unconfirmed nuclear weapon currently, or at some point in history, or research programs with a realistic chance of producing a nuclear weapon in the near future:

States formerly possessing nuclear weapons or programs

These are nations known to have initiated serious nuclear weapons programs, with varying degrees of success. All of them are now regarded as currently no longer actively developing, or possessing, nuclear arms.

Other nuclear capable states

Virtually any industrialized nation today has the technical capability to develop nuclear weapons within several years if the decision to do so were made. Nations already possessing substantial nuclear technology and arms industries could do so in no more than a year or two. The larger industrial nations (Japan and Germany for example) could, within several years of deciding to do so, build arsenals rivaling those planned by Russia and the U.S. This list below mentions some notable capabilities possessed by certain states that could potentially be turned to the development of nuclear arsenals. It should also be noted that this list represents only strong nuclear capability, not that any political will to develop such weapon would exist. All of the listed countries signed the Nuclear Non-Proliferation Treaty.
