United States

Main article: United States and weapons of mass destruction

Note: US 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 W-91 missile warhead (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.

In some cases, such as B53 nuclear bomb and W-53 warhead, and the W54 and Davy Crockett Mk-54, the same core nuclear system was used in multiple applications. This is indicated by the same sequence number for all versions of that nuclear weapon system.

In other cases, variants are assigned their own number, such as the B61 nuclear bomb which was the parent design for the W80, W81, and W84.

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 as listed as canceled, along with the year or date of cancellation of their program.

  • Bombs — designated with Mark ("Mk") numbers until 1968, and with "B" numbers after that. "Test Experimental" bombs designated with "TX".
    • Mark 1 – "Little Boy" gun-type weapon (used against Hiroshima). (13-16 Kt, 1945-1950)

Soviet Union/Russia

Main article: Russia and weapons of mass destruction

At the peak of its arsenal, Russia possessed around 16,000 nuclear weapons in its stockpile, rivaled only by the United States arsenal.

  • Tests
  • Torpedoes
  • Bombs
    • RDS-1, 22 kiloton bomb. Tested 29 August 1949 as "First Light" (Joe 1). Total of 5 stockpiled
    • RDS-2, 38 kiloton bomb. Tested 24 September 1951 as "Second Light." The RDS-2 was an entirely Russian design, delayed by development of the RDS-1
    • RDS-3, 42 kiloton bomb. First Soviet bomb tested in an airdrop on 18 October 1951. First 'mass produced" Soviet bomb
    • RDS-31, 62 kiloton bomb. Tested 24 October 1954. The RDS-31 was an improved RDS-3 with external neutron generator
    • RDS-4, "Tatyana" 42 kiloton bomb. The RDS-4 was smaller and lighter than previous Soviet Bombs.
    • RDS-6, also known as RDS-6S, or "sloika" or 'layer cake" gaining about 20% of its yield from fusion. RDS-6 was tested on 12 August 1953. Yield 400 kilotons
    • RDS-7, a backup for the RDS-6, the RDS-7 was a 500 kiloton all fission bomb comparable to the US Mk-18, development dropped after success of the RDS-6S
    • RDS-27, 250 kiloton bomb, a 'boosted' fission bomb tested 6 November 1955.
    • RDS-37, 1.6 megaton bomb, the first Soviet two-stage hydrogen bomb, tested 22 November 1955
    • RDS-220 Tsar Bomba an extremely large three stage bomb, initially designed as an 100-megaton-bomb, but was scaled down to 50 megatons for testing.
  • ICBM Missiles
  • Various tactical nuclear weapons including "suitcase bombs"

United Kingdom

Main article: United Kingdom and Weapons of Mass Destruction

The United Kingdom is said to have an arsenal of 350 nuclear weapons stockpiled as of 2001.

Although the stockpile of "operationally available warheads" was reduced from 300 to less than 200 in 1998. [citation needed]

Canada

Main article: Canada and weapons of mass destruction

Canada has not maintained a stockpile of nuclear weapons since 1984.

France

Main article: France and weapons of mass destruction

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

China

Main article: China and weapons of mass destruction

China is believed to possess around 400 nuclear weapons, but has released very little information about the contents of its arsenal.

India

Main article: India and weapons of mass destruction

India is said to possess between 60-120 nuclear weapons, although not many are thought to be ready for use. The specifications of its weapons are not public.

Iran

Main article: Iran and weapons of mass destruction

Persistent rumors throughout the 1990s that Iran had obtained ex-Soviet nuclear weapons have never been confirmed or conclusively refuted.

Iran is actively seeking nuclear capability, which they state is not for military use.

Many experts have concluded that Iran's contemporary late 1990s and 2000 formerly covert uranium enrichment program was part of a secret nuclear weapons program. Iran disputes this conclusion. As of April 2007, the International Atomic Energy Agency and United Nations Security Council are involved in addressing this question. Also unconfirmed reports from April 12 2007 Iranian President, Mahmoud Ahmadinejad, announced that Iran has enriched uranium. As of April 13 2007 Iran now demands to be seen as a nuclear power.[citation needed] The UN has voted to sanction Iran if it doesn't shut down its uranium enriching facilities. Recently Iran has failed to meet the deadline.

Israel

Main article: Israel and weapons of mass destruction

Israel is widely believed to possess a substantial arsenal of nuclear weapons and missiles, estimated at 75-130 and 100-200[1] 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. [2]

The BBC News Online website published an article[6] on the 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. Defence Secretary Robert Gates at a Senate hearing and had apparently been confirmed a short time later by Israeli Prime Minister Ehud Olmert. [3]

Pakistan

Main article: Pakistan and weapons of mass destruction

Pakistan is believed to have around 40-60 HEU based nuclear weapons.Though Plutonium based research is also available but the estimated stockpile is not enough to be comparable to Uranium ones, however the specifications of these are not available publicly. The main series for nuclear transportation is Hatf.

The first two in the above mentioned series are not confirmed to be capable for nuclear standoff

North Korea

Main article: North Korea and weapons of mass destruction

North Korea claims to possess nuclear weapons, however, the specifications of its systems are not public. On 9 October 2006, North Korea carried out an alleged nuclear test. (See 2006 North Korean nuclear test)

South Africa

Main article: South Africa and weapons of mass destruction

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.
