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 ...
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
However, within the same Nuclear Posture Review of April 2010, there was a stated need to develop new “low yield” nuclear weapons. This resulted in the development of the B61 Mod 12. [ 91 ] Despite President Obama's goal of a nuclear-free world and reversal of former President Bush's nuclear policies, his presidency cut fewer warheads from ...

The United States is known to have possessed three types of weapons of mass destruction: nuclear, chemical, and biological weapons.As the country that invented nuclear weapons, the U.S. is the only country to have used nuclear weapons on another country, when it detonated two atomic bombs over two Japanese cities of Hiroshima and Nagasaki during World War II.
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 weapon is notable for being the smallest nuclear weapon in both weight and yield to have entered US service. It was a compact implosion device containing plutonium-239 as its fissile material, [ 1 ] and in its various versions and mods it had a yield of 10 to 1,000 tons of TNT (42 to 4,184 gigajoules ).
The MOAB is the most powerful conventional bomb ever used in combat as measured by the weight of its explosive material. [29] [30] The explosive yield is comparable to that of the smallest tactical nuclear weapons, such as the Cold War-era American M-388 projectile fired by the portable Davy Crockett recoilless gun.
