- Nuclear weapon : A weapon that produces extremely powerful explosions from principles involving subatomic particle reactions, rather than the chemical reactions among atoms that power conventional explosives
- World War II : War between the Allies (most notably the UK, US and Soviet Union) and the Axis (principally Germany and Japan) 1939–1945.
- Manhattan Project : Code name for the U.S. nuclear weapon development program in the World War II
- Los Alamos National Laboratory : A U.S. Department of Energy (DOE) national laboratory located in Los Alamos, New Mexico and originally the development and construction center of nuclear weapons during the Manhattan Project for use by the United States in World War II.
- Fission device : An assembly of components, not necessarily in a form usable as a weapon, which will produce a large energy release through nuclear fission
- Fusion device : An explosive device, whether used as a weapon or for other purposes, which depends for most of its explosive power on the release of energy by combining atomic nuclei
- Barytol : A mixture of 24% TNT and 76% barium nitrate, used in the Fat Man (nuclear weapon) as a "slow explosive" to shape compression waves in the implosion system; detonation velocity of 4,870 m/sec and cast density 2.55.
- Little Boy (nuclear weapon) : Code name for the first nuclear weapon used in warfare, dropped on Hiroshima, Japan, on August 6, 1945; gun-type uranium fission; also designated Mark I
- Nuclear fission : A reaction by which a nucleus of a suitable isotope of an element with a high atomic number splits into two nuclei of lower atomic numbers and one or more neutrons and a relatively large release of energy per atom.
- Plutonium : Man-made radioactive element (Z = 94); its 239 isotope is fissionable and used in nuclear weapons; the 240 isotope is used in some nuclear power reactors
- TNT equivalent : A unit of energy commonly used to quantify the energy released (or "yielded") in explosions.
- Mark 4 (nuclear weapon) : Still first-generation but a production-quality, re-engineered version of the Fat Man bomb, the yield of which could be varied from 1, 3.5, 8, 14, 21, 22, and 31 kt TNT equivalent by exchanging the plutonium pits; first weapon made on an assembly line rather than by hand; design ancestor of the British Blue Danube bomb
