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 ).
Its explosive yield was extremely small for a nuclear weapon. [4] [5] In the mid-1970s, debate shifted from the possibility of developing such a device for the military to concerns over its possible use in nuclear terrorism. [6] The concept became a staple of the spy thriller genre in the later Cold War era. [7]
The lack of compression makes such designs inefficient, but the simplicity and small diameter make it suitable for use in artillery shells and atomic demolition munitions – ADMs – also known as backpack or suitcase nukes; an example is the W48 artillery shell, the smallest nuclear weapon ever built or deployed. All such low-yield ...
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 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
For the first time in nearly 60 years, Russian energy corporation Rosatom has released video of the most powerful nuclear bomb ever to be detonated on Earth, reported IFL Science. The enthralling ...
Advances in nuclear weapons technology, spurred on by the first detonation of the Soviet nuclear bomb in 1949, led to great reductions in the size of nuclear weapons. By 1957, the Atomic Energy Commission (AEC) declared that it had created a small fission warhead that could be deployed for frontline use by infantrymen.
A tactical nuclear weapon, it was manufactured starting in 1963, and all units were retired in 1992. It was known as the XM454 AFAP (artillery fired atomic projectile) in US service. The weapon was 34 inches (86 cm) long and weighed 120 pounds (54 kg), and was produced in two versions; the Mod 0 and Mod 1. Declassified British document give the ...
