Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
Weapons variable yield and weight have been plotted at their highest yield and weight. Also indicated on the graph are a few characteristics of the weapons (Little Boy and Fat Man, the early H-bombs, small tactical weapons, and weapons in the enduring stockpile separated by missile warheads and air-dropped bombs).
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.
The B61 nuclear bomb is the primary thermonuclear gravity bomb in the United States Enduring Stockpile following the end of the Cold War.It is a low-to-intermediate yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design.
Trinity test on 16 July 1945, was the world's first test of a nuclear weapon (yield of around 20 kt). Operation Crossroads series in July 1946, was the first postwar test series and one of the largest military operations in U.S. history.
Iran has defied international demands to rein in its nuclear program and has increased its stockpile of uranium enriched to near weapons-grade levels, according to a confidential report by the ...
The neutron release generated by a nuclear fusion reaction is intentionally allowed to escape the weapon, rather than being absorbed by its other components. [3] The neutron burst, which is used as the primary destructive action of the warhead, is able to penetrate enemy armor more effectively than a conventional warhead, thus making it more ...
The devices and related infrastructure improvements, needed “to inform plans for modernizing the nuclear weapons stockpile” will cost about $2.5 billion to $2.6 billion and be ready by 2030 ...
