The components of a B83 nuclear bomb used by the United States

This is a list of nuclear weapons listed according to country of origin, and then by type within the states.

United States

American nuclear weapons of all types – bombs, warheads, shells, and others – are numbered in the same sequence starting with the Mark 1 and (as of March 2006) ending with the W91 (which was canceled prior to introduction into service). All designs which were formally intended to be weapons at some point received a number designation. Pure test units which were experiments (and not intended to be weapons) are not numbered in this sequence.

Early weapons were very large and could only be used as free fall bombs. These were known by "Mark" designators, like the Mark 4 which was a development of the Fat Man weapon. As weapons became more sophisticated they also became much smaller and lighter, allowing them to be used in many roles. At this time the weapons began to receive designations based on their role; bombs were given the prefix "B", while the same warhead used in other roles, like missiles, would normally be prefixed "W". For instance, the W-53 warhead was also used as the basis for the B53 nuclear bomb. Such examples share the same sequence number.

In other cases, when the modifications are more significant, variants are assigned their own number. An example is the B61 nuclear bomb, which was the parent design for the W80, W81, and W84. There are also examples of out-of-sequence numbering and other prefixes used in special occasions.

This list includes weapons which were developed to the point of being assigned a model number (and in many cases, prototypes were test fired), but which were then canceled prior to introduction into military service. Those models are listed as canceled, along with the year or date of cancellation of their program.

Soviet Union/Russia

At the peak of its arsenal in 1988, Russia possessed around 45,000 nuclear weapons in its stockpile, roughly 13,000 more than the United States arsenal, the second largest in the world, which peaked in 1966.[2]

United Kingdom

  • Blue Steel
  • Yellow Sun productionised air-delivered thermonuclear bomb casing.

    • Blue Cat – nuclear warhead a.k.a. Tony - UK version of US W44, a.k.a. Tsetse.
    • Blue Fox – kiloton range nuclear weapon, later renamed Indigo Hammer - not to be confused with the later Blue Fox radar.
    • Blue Peacock ten-kiloton nuclear land mine, a.k.a. the "chicken-powered nuclear bomb", originally 'Blue Bunny' It used the Blue Danube physics package.
    • Blue Rosette – short-case nuclear weapon bomb casing for reconnaissance bomber to spec R156T, including the Avro 730, Handley Page HP.100, English Electric P10, Vickers SP4 and various others.

    • Green Grass – nuclear weapon
    • Indigo Hammer – nuclear weapon
    • Orange Herald – fusion-boosted fission weapon. It is believed that the fusion boost didn't work, which would make it the most powerful fission bomb ever tested at 720 kt.
    • Violet Club – nuclear weapon

France

France is said to have an arsenal of 350 nuclear weapons stockpiled as of 2002.

China

China is believed to possess around 250 nuclear weapons, but has released very little information about the contents of its arsenal.

India

Although India's nuclear programme and its details are highly classified, international figures suggest that India possesses about 150 nuclear weapons, with enough weapons-grade plutonium for another 150–200 nuclear weapons (2020 estimate). In 1999, India was estimated to have 800 kg of separated reactor-grade plutonium, with a total amount of 8,300 kg of civilian plutonium, enough for approximately 1,000 nuclear weapons.[6][7][8]

Israel

Israel is widely believed to possess a substantial arsenal of nuclear weapons and missiles, estimated at 75–130 and 100–200[9] warheads, but refuses officially to confirm or deny whether it has a nuclear weapon program, leaving the details of any such weapons unclear. Mordechai Vanunu, a former nuclear technician for Israel, confirmed the existence of a nuclear weapons program in 1986.

Unconfirmed rumors have hinted at tactical nuclear artillery shells, light fission bombs and missile warheads, and perhaps thermonuclear missile warheads.[10]

The BBC News Online website published an article[11] on 28 May 2008, which quotes former U.S. President Jimmy Carter as stating that Israel has at least 150 nuclear weapons. The article continues to state that this is the second confirmation of Israel's nuclear capability by a U.S. spokesman following comments from U.S. Defense Secretary Robert Gates at a Senate hearing and had apparently been confirmed a short time later by Israeli Prime Minister Ehud Olmert.[12]

Pakistan

As of June 2019, Pakistan is believed to possess about 160 nuclear weapons. The specifications of its weapon production are not disclosed to the public. The main series for nuclear transportation is Hatf (lit. Target).[13][14]

North Korea

North Korea claims to possess nuclear weapons, however, the specifications of its systems are not public. It is estimated to have 6–18 low yield nuclear weapons (August 2012 estimate).[15] On 9 October 2006, North Korea achieved its first nuclear detonation.

On 25 May 2009, North Korea conducted a second test of nuclear weapons at the same location as the original test. The test weapon was of the same magnitude as the atomic bombs dropped on Japan in the 2nd World War. At the same time of the test, North Korea tested two short range ballistic missiles. The country tested a 7 kt nuclear weapon on 2 February 2013. On 3 September 2017, North Korea conducted an underground thermonuclear test which had an estimated yield of 100kt to 250kt, according to various sources.

On March 24, 2023, North Korea unveiled the Hwasal-31 화살-31 tactical nuclear bomb with at least 10 warheads shown, each measuring an estimated 40 to 50 centimeters in diameter and 1 meter in length as reported by the South Korean media. KN-23 and KN-25 ballistic missiles are capable of carrying it.[16][17][18]

South Africa

South Africa built six or seven gun-type weapons. All constructed weapons were verified by International Atomic Energy Agency and other international observers to have been dismantled, along with the complete weapons program, and their highly enriched uranium was reprocessed back into low enriched form unsuitable for weapons.
