List of nuclear weapons
This is a list of nuclear weapons listed according to country of origin, and then by type within the states.
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[update]) ending with the W-91 (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/Russian Federation

France is said to have an arsenal of 350 nuclear weapons stockpiled as of 2002.
- Warheads (and missiles)
China is believed to possess around 250 nuclear weapons, but has released very little information about the contents of its arsenal.
- Ballistic Missiles:
- Cruise Missiles
India is believed to possess between 100-150 nuclear weapons (March 2010 estimate). The specifications of its weapon production are not disclosed to the public.
Israel is widely believed to possess a substantial arsenal of nuclear weapons and missiles, estimated at 75-130 and 100-200 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.
The BBC News Online website published an article 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.
As of March 2010, Pakistan is believed to possess between 90-120 nuclear weapons. The specifications of its weapon production are not disclosed to the public. The main series for nuclear transportation is Hatf.
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). On 9 October 2006, North Korea carried out an alleged nuclear test. (See 2006 North Korean nuclear test) Nuclear weapons produced by North Korea are known to have failed.
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. North Korea is continuously carrying out nuclear tests, such as on 2 February 2013, when it tested a 7 kt nuclear weapon.
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.
