nuclear weapon
Also known as nuke, atomic weapon, nuclear arms, nuclear weaponry
explosive device that gets its destructive force from nuclear reactions
AI overview
A nuclear weapon is an explosive device that uses nuclear reactions—the splitting or combining of atoms—to create enormous destructive force. These weapons matter because they can cause unprecedented damage over vast areas, making them central to international security concerns and global politics.

Article
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either nuclear fission (fission or atomic bomb) or a combination of fission and nuclear fusion reactions (thermonuclear weapon), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. Nine sovereign states are believed to possess nuclear weapons as of 2026: the United States, Russia, the United Kingdom, France, China, India, Pakistan, North Korea and Israel.
The majority of nuclear weapons have energy yields between 100 and 1,000 kilotons of TNT. Yields in the low kilotons can destroy cities. The effects of nuclear weapons include extreme blast damage, heat, ionizing radiation, and firestorms, followed by radioactive nuclear fallout, an electromagnetic pulse, radar blackout, and acute or chronic radiation syndrome in humans and animals. Hundreds of nuclear explosions would likely cause nuclear winter and nuclear famine.
