A nuclear weapon [a] is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.
A B61 nuclear bomb in various stages of assembly; the nuclear warhead is the bullet-shaped silver canister in the middle-left of the photograph.. A warhead is the section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb.
W80 Mod 1 warhead W80 Mod 4 warhead for the LRSO program.. The W80 is a low to intermediate yield two-stage thermonuclear warhead deployed by the U.S. enduring stockpile with a variable yield ("dial-a-yield") of 5 or 150 kilotonnes of TNT (21 or 628 TJ).
The warhead used enriched uranium (code named oralloy) as its nuclear fissile material and could be used in two different yield configurations. This required the assembly and insertion of different pits , with the amount of fissile materials used controlling whether the destructive yield was low or high.
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. . The United States, Russia, China and India are known to possess a nuclear triad, being capable to deliver nuclear weapons by land, sea and
The Yearbook published by SIPRI in 2024 revealed that China's nuclear warheads stockpile increased by 90 in 2023, reaching 500 warheads. [65] US Department of Defense officials estimate that the Chinese had more than 600 operational nuclear warheads as of December 2024, and it was on track to posess 1,000 nuclear weapons by the year 2030.

Exploded diagram of the Mk21 reentry vehicle for the W87 [clarification needed]. The W87 is an American thermonuclear missile warhead formerly deployed on the LGM-118A Peacekeeper ("MX") ICBM. 50 MX missiles were built, each carrying up to 10 W87 warheads in multiple independently targetable reentry vehicles (MIRV), and were deployed from 1986 to 2005.
