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.

What is a nuclear weapon? A nuclear weapon is a device designed to release energy in an explosive manner as a result of nuclear fission, nuclear fusion, or a combination of the two processes. Are there treaties to control the proliferation of nuclear weapons?

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 air.

Five are considered to be nuclear-weapon states (NWS) under the terms of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). In order of acquisition of nuclear weapons, these are the United States, Russia (the successor of the former Soviet Union), the United Kingdom, France, and China.

Today, the United States deploys 1,419 and Russia deploys 1,549 strategic warheads on several hundred bombers and missiles, and are modernizing their nuclear delivery systems. Warheads are counted using the provisions of the New START agreement, which was extended for 5 years in January 2021.

Nine countries currently have nuclear weapons: Russia, the United States, China, France, the United Kingdom, Pakistan, India, Israel, and North Korea. These nuclear powers differ a lot in how many nuclear warheads they have. The chart shows that while most have dozens or a few hundred warheads, Russia and the United States have thousands of them.

3 days ago · Nuclear weapons are fundamentally different from conventional weapons because of the vast amounts of explosive energy they can release and the kinds of effects they produce, such as high temperatures and radiation.

Apr 17, 2024 · A nuclear weapon is a device that uses a nuclear reaction to create an explosion. This explosion is much more powerful than that of conventional explosives (like TNT). When a nuclear weapon explodes, it gives off four types of energy: a …

One of NNSA’s core missions is to ensure the United States maintains a safe, secure, and reliable nuclear stockpile. These weapons—along with the submarines, ballistic missiles, and aircraft that deliver them—constitute the nation’s strategic deterrent.

Nuclear weapons are the most potent explosive devices ever invented. Their destructive effects include not only a blast equivalent to thousands of tons of TNT but also blinding light, searing heat, and lethal radioactive fallout.
