List of nuclear weapons

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[update]) ending with the W91 (which was cancelled prior to introduction into service).

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 cancelled prior to introduction into military service.

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

[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.

[13][14] North Korea claims to possess nuclear weapons, however, the specifications of its systems are not public.

The test weapon was of the same magnitude as the atomic bombs dropped on Japan in the 2nd World War.

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 [ko] 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.
