Five are considered to be nuclear-weapon states (NWS) under the terms of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). In order of acquisition of nuclear weapons these are the United States, Russia (the successor state to the Soviet Union), the United Kingdom, France, and China.Since the NPT entered into force in 1970, three states that were not parties to the Treaty have conducted overt nuclear tests, namely India, Pakistan, and North Korea.

Statistics and force configuration

{{Weapons of mass destruction}}The following is a list of states that have admitted the possession of nuclear weapons or are presumed to possess them, the approximate number of warheads under their control, and the year they tested their first weapon and their force configuration. This list is informally known in global politics as the "Nuclear Club"."Nuclear club", Oxford English Dictionary: "nuclear club n. the nations that possess nuclear weapons." The term's first cited usage is from 1957.Jane Onyanga-Omara, "The Nuclear Club: Who are the 9 members?" {{Webarchive|url= |date=2017-09-04 }}, USA TODAY, 6 January 2016 With the exception of Russia and the United States (which have subjected their nuclear forces to independent verification under various treaties) these figures are estimates, in some cases quite unreliable estimates. In particular, under the Strategic Offensive Reductions Treaty thousands of Russian and U.S. nuclear warheads are inactive in stockpiles awaiting processing. The fissile material contained in the warheads can then be recycled for use in nuclear reactors.From a high of 70,300 active weapons in 1986, {{as of|2019|lc=on||df=}} there are approximately 3,750 active nuclear warheads and 13,890 total nuclear warheads in the world.WEB,weblink World Nuclear Forces, SIPRI yearbook 2019, July 2019, Stockholm International Peace Research Institute, Stockholm International Peace Research Institute, 18 June 2015, live, 5 August 2019, Many of the decommissioned weapons were simply stored or partially dismantled, not destroyed.Webster, Paul (July/August 2003).

When a range of weapons is given (e.g., 0–10), it generally indicates that the estimate is being made on the amount of fissile material that has likely been produced, and the amount of fissile material needed per warhead depends on estimates of a country's proficiency at nuclear weapon design.|group=nb}}!

Five nuclear-weapon states under the NPT

{{See also|History of nuclear weapons}}These five states are known to have detonated a nuclear explosive before 1 January 1967 and are thus nuclear weapons states under the Treaty on the Non-Proliferation of Nuclear Weapons. They also happen to be the UN Security Council's permanent members with veto power on UNSC resolutions.

United States

File:Trinity Test Fireball 16ms.jpg|right|thumb|An early stage in the "Trinity" fireball, the first nuclear explosionnuclear explosionThe United States developed the first nuclear weapons during World War II in cooperation with the United Kingdom and Canada as part of the Manhattan Project, out of the fear that Nazi Germany would develop them first. It tested the first nuclear weapon on July 16, 1945 ("Trinity") at 5:30 am, and remains the only country to have used nuclear weapons in war, devastating the Japanese cities of Hiroshima and Nagasaki. It was the first nation to develop the hydrogen bomb, testing an experimental prototype in 1952 ("Ivy Mike") and a deployable weapon in 1954 ("Castle Bravo"). Throughout the Cold War it continued to modernize and enlarge its nuclear arsenal, but from 1992 on has been involved primarily in a program of Stockpile stewardship.BOOK, Chuck, Hansen, U.S. nuclear weapons: The secret history, Arlington, TX, Aerofax, 1988, 978-0-517-56740-1, BOOK, Chuck, Hansen, The Swords of Armageddon: U.S. nuclear weapons development since 1945, Sunnyvale, CA, Chukelea Publications, 1995,weblink 2016-02-20,weblink" title="">weblink 2016-12-30, live, Stephen I.

Russia (formerly part of the Soviet Union)

{{See also|Soviet atomic bomb project}}(File:US and USSR nuclear stockpiles.svg|thumb|U.S. and USSR/Russian nuclear weapons stockpiles, 1945–2014)The Soviet Union tested its first nuclear weapon ("RDS-1") in 1949. This crash project was developed partially with information obtained via espionage during and after World War II. The Soviet Union was the second nation to have developed and tested a nuclear weapon. The direct motivation for Soviet weapons development was to achieve a balance of power during the Cold War. It tested its first megaton-range hydrogen bomb ("RDS-37") in 1955. The Soviet Union also tested the most powerful explosive ever detonated by humans, ("Tsar Bomba"), with a theoretical yield of 100 megatons, intentionally reduced to 50 when detonated. After its dissolution in 1991, the Soviet weapons entered officially into the possession of the Russian Federation.BOOK, David, Holloway, Stalin and the bomb: The Soviet Union and atomic energy, 1939-1956, New Haven, CT, Yale University Press, 1994, 978-0-300-06056-0, The Soviet nuclear arsenal contained some 45,000 warheads at its peak (in 1986); the Soviet Union built about 55,000 nuclear warheads since 1949.

United Kingdom

File:Trident II missile image.jpg|thumb|right|A Trident missile launched from a Royal Navy Vanguard class ballistic missile submarineballistic missile submarineThe United Kingdom tested its first nuclear weapon ("Hurricane") in 1952. The UK had provided considerable impetus and initial research for the early conception of the atomic bomb, aided by Austrian, German and Polish physicists working at British universities who had either fled or decided not to return to Nazi Germany or Nazi controlled territories. The UK collaborated closely with the United States and Canada during the Manhattan Project, but had to develop its own method for manufacturing and detonating a bomb as U.S. secrecy grew after 1945. The United Kingdom was the third country in the world, after the United States and Soviet Union, to develop and test a nuclear weapon. Its programme was motivated to have an independent deterrent against the Soviet Union, while also maintaining its status as a great power. It tested its first hydrogen bomb in 1957 (Operation Grapple), making it the third country to do so after the United States and Soviet Union.BOOK, Margaret, Gowing, Independence and deterrence: Britain and atomic energy, 1945-1952, London, Macmillan, 1974, 978-0-333-15781-7, BOOK, Lorna, Arnold, Britain and the H-bomb, Basingstoke, Palgrave, 2001, 978-0-312-23518-5, The UK maintained a fleet of V bomber strategic bombers and ballistic missile submarines (SSBNs) equipped with nuclear weapons during the Cold War. It currently maintains a fleet of four 'Vanguard' class ballistic missile submarines equipped with Trident II missiles. In 2016, the UK House of Commons voted to renew the British nuclear weapons system with the Dreadnought-class submarine, without setting a date for the commencement of service of a replacement to the current system.

It was motivated by the Suez Crisis diplomatic tension vis-à-vis both the Soviet Union and its allies, the United States and United Kingdom. It was also relevant to retain great power status, alongside the United Kingdom, during the post-colonial Cold War (see: Force de frappe). France tested its first hydrogen bomb in 1968 ("Opération Canopus"). After the Cold War, France has disarmed 175 warheads with the reduction and modernization of its arsenal that has now evolved to a dual system based on submarine-launched ballistic missiles (SLBMs) and medium-range air-to-surface missiles (Rafale fighter-bombers).

China tested its first nuclear weapon device ("596") in 1964 at the Lop Nur test site. The weapon was developed as a deterrent against both the United States and the Soviet Union. Two years later, China had a fission bomb capable of being put onto a nuclear missile. It tested its first hydrogen bomb ("Test No. 6") in 1967, a mere 32 months after testing its first nuclear weapon (the shortest fission-to-fusion development known in history).John Wilson Lewis and Xue Litai, China Builds the Bomb (Stanford, Calif.: Stanford University Press, 1988). {{ISBN|0-8047-1452-5}} China is the only NPT nuclear-weapon state to give an unqualified negative security assurance with its "no first use" policy.WEB,weblink No-First-Use (NFU), Nuclear Threat Initiative,weblink" title="">weblink 2010-01-25, JOURNAL,weblinkweblink" title="">weblink 2007-08-24, Statement on security assurances issued on 5 April 1995 by the People's Republic of China, United Nations, 6 April 1995, S/1995/265, 20 September 2012, China signed the Nuclear Non-Proliferation Treaty in 1992.

India is not a party to the Nuclear Non-Proliferation Treaty. India tested what it called a "peaceful nuclear explosive" in 1974 (which became known as "Smiling Buddha"). The test was the first test developed after the creation of the NPT, and created new questions about how civilian nuclear technology could be diverted secretly to weapons purposes (dual-use technology). India's secret development caused great concern and anger particularly from nations that had supplied its nuclear reactors for peaceful and power generating needs, such as Canada.WEB, 18 MAY 1974 - SMILING BUDDAH,weblink CTBTO, 24 January 2018, Indian officials rejected the NPT in the 1960s on the grounds that it created a world of nuclear "haves" and "have-nots", arguing that it unnecessarily restricted "peaceful activity" (including "peaceful nuclear explosives"), and that India would not accede to international control of their nuclear facilities unless all other countries engaged in unilateral disarmament of their own nuclear weapons. The Indian position has also asserted that the NPT is in many ways a neo-colonial regime designed to deny security to post-colonial powers.George Perkovich, India's Nuclear Bomb: The Impact on Global Proliferation (Berkeley: University of California Press, 1999), 120-121, and 7. Even after its 1974 test, India maintained that its nuclear capability was primarily "peaceful", but between 1988 and 1990 it apparently weaponized two dozen nuclear weapons for delivery by air.George Perkovich, India's Nuclear Bomb: The Impact on Global Proliferation (Berkeley: University of California Press, 1999), 293–297.

Pakistan also is not a party to the Nuclear Non-Proliferation Treaty. Pakistan covertly developed nuclear weapons over decades, beginning in the late 1970s. Pakistan first delved into nuclear power after the establishment of its first nuclear power plant near Karachi with equipment and materials supplied mainly by western nations in the early 1970s.

In October 2006, North Korea stated that, in response to growing intimidation by the United States, it would conduct a nuclear test to confirm its nuclear status. North Korea reported a successful nuclear test on October 9, 2006 (see 2006 North Korean nuclear test).

Other states believed to possess nuclear weapons


Israel is widely believed to have been the sixth country in the world to develop nuclear weapons, but has not acknowledged its nuclear forces. It had "rudimentary, but deliverable," nuclear weapons available as early as 1966.{{Sfn | Cohen | 1998a | p = 349}}WEB, Mohamed, ElBaradei,weblink Transcript of the Director General's Interview with Al-Ahram News, Mohamed ElBaradei, International Atomic Energy Agency, July 27, 2004, June 3, 2007,weblink" title="">weblink April 18, 2012, live, WEB, June 23, 2009, Israel, Nuclear Overview, profile, NTI,weblink dead,weblink" title="">weblink January 2, 2009, My Promised Land, by Ari Shavit, (London 2014), page 188WEB, Israel's Quest for Yellowcake: The Secret Argentina-Israel Connection, 1963–1966, Nuclear Proliferation International History Project,weblink Woodrow Wilson International Center for Scholars, 2013-06-28, 2017-11-22,weblink 2017-08-14, live, WEB,weblink Nuclear Weapons, John Pike,, 2017-11-22,weblink 2017-11-17, live, WEB,weblink Nuclear Weapons,, 2015-11-07,weblink" title="">weblink 2010-12-07, live, NTI Israel Profile {{Webarchive|url= |date=2011-07-28 }} Retrieved July 12, 2007. Israel is not a party to the NPT. Israel engages in strategic ambiguity, saying it would not be the first country to "introduce" nuclear weapons into the region, but refusing to otherwise confirm or deny a nuclear weapons program or arsenal. This policy of "nuclear opacity" has been interpreted as an attempt to get the benefits of deterrence with a minimal political cost.According to the Natural Resources Defense Council and the Federation of American Scientists, Israel likely possesses around 75–200 nuclear weapons.There are a wide range of estimates as to the size of the Israeli nuclear arsenal. For a compiled list of estimates, see Avner Cohen, The Worst-Kept Secret: Israel's bargain with the Bomb (Columbia University Press, 2010), Table 1, page xxvii and page 82.Israel's Nuclear Weapons {{Webarchive|url= |date=2010-12-07 }}, Federation of American Scientists (August 17, 2000) The Stockholm International Peace Research Institute estimates that Israel has approximately 80 intact nuclear weapons, of which 50 are for delivery by Jericho II medium-range ballistic missiles and 30 are gravity bombs for delivery by aircraft.

States formerly possessing nuclear weapons

Nuclear weapons have been present in many nations, often as staging grounds under control of other powers. However, in only one instance has a nation given up nuclear weapons after being in full control of them. The fall of the Soviet Union left several former Soviet republics in physical possession of nuclear weapons, though not operational control which was dependent on Russian-controlled electronic Permissive Action Links and the Russian command and control system.BOOK,weblink Why Ukraine gave up nuclear weapons : nonproliferation incentives and disincentives, William C.

South Africa

South Africa produced six nuclear weapons in the 1980s, but dismantled them in the early 1990s.In 1979, there was a detection of a putative covert nuclear test in the Indian Ocean, called the Vela incident. It has long been speculated that it was a test by Israel, in collaboration with and support of South Africa, though this has never been confirmed. South Africa could not have constructed such a nuclear bomb until November 1979, two months after the "double flash" incident.South Africa signed the Nuclear Non-Proliferation Treaty in 1991.Nuclear Weapons Program (South Africa) {{Webarchive|url= |date=2015-10-16 }}, Federation of American Scientists (May 29, 2000).Von Wielligh, N. & von Wielligh-Steyn, L.
