The lightest nuclear warhead ever acknowledged to have been manufactured by the U.S. is the W54, which was used in both the Davy Crockett 120 mm recoilless rifle-launched warhead and the backpack-carried version called the Mk-54 SADM (Special Atomic Demolition Munition). The bare warhead package was an 11 by 16 inches (280 by 410 mm) cylinder ...
Nukemap (stylised in all caps) is an interactive map using Mapbox [1] API and declassified nuclear weapons effects data, created by Alex Wellerstein, a historian of science at the Stevens Institute of Technology who studies the history of nuclear weapons. The initial version was created in February 2012, with major upgrades in July 2013, [2] [3 ...
With the decreased cost and increased capabilities of computers, Nuclear Engineering has implemented computer software (Computer code to Mathematical model) into all facets of this field. There are a wide variety of fields associated with nuclear engineering, but computers and associated software are used most often in design and analysis.
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 ...
Tactical nuclear weapons were a large part of the peak nuclear weapons stockpile levels during the Cold War. US scientists with a full-scale cut-away model of the W48, a very small tactical nuclear weapon with an explosive yield equivalent to 72 tons of TNT (0.072 kiloton). Around 100 of such shells were produced during the Cold War.
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 ).
In a worst case analysis, a suitcase nuke would be small enough to be hand-carried into a major population or leadership center undetected and then detonated. Although, by most accounts, the yield of such a device is likely far less than ten kilotons, its combined effects may have the potential to kill tens of thousands, if not more. There is a ...
The instruments would have detected any nuclear explosions and indicated the estimated size in megatons. With the display unit mounted in a 3-foot-high (0.91 m) steel cabinet, the system used two sets of five photo-sensitive cells within the detection head to record the intense flash of light produced by the detonation of the weapon followed ...
