A nuclear bunker buster, [1] also known as an earth-penetrating weapon (EPW), is the nuclear equivalent of the conventional bunker buster. The non-nuclear component of the weapon is designed to penetrate soil , rock , or concrete to deliver a nuclear warhead to an underground target.
The weapon was produced in two models; the enhanced radiation (ERW) W79 Mod 0 and fission-only W79 Mod 1. Both were plutonium -based linear-implosion nuclear weapons . The Mod 0 was a variable yield device with three yields, ranging from 100 tons of TNT (420 GJ ) up to 1.1 kt (4.6 TJ ) and an enhanced- radiation mode which could be turned on or off
The Mark 105 Hotpoint was an airdropped nuclear bomb developed for the United States Navy using the 11 kiloton W34 warhead. It was developed in the 1950s as the first nuclear bomb purposely designed for laydown delivery (bunker buster) but could also be used for airburst or as a depth charge. The laydown mechanism utilized both a retarding ...
The remaining bomb casings are located at the Russian Atomic Weapon Museum in Sarov and the Museum of Nuclear Weapons, All-Russian Scientific Research Institute Of Technical Physics, in Snezhinsk. Tsar Bomba was a modification of an earlier project, RN202, which used a ballistic case of the same size but a very different internal mechanism. [16]
The weapons were to be built by converting existing B61-0, −2 and −5 weapons into Mod 6 and 8 weapons and the weapons were to use B61-7 weapon parts where possible. [33] By mass, the largest deviations from the B61-7 were the Acorn assembly, MC4137 TSSG (trajectory sensing signal generator) and the JTA (described as "ballast for WR").
Weapons-grade nuclear material is any fissionable nuclear material that is pure enough to make a nuclear weapon and has properties that make it particularly suitable for nuclear weapons use. Plutonium and uranium in grades normally used in nuclear weapons are the most common examples.
W70 was a two-stage, thermonuclear warhead that was developed for the MGM-52 Lance missile by the United States.Designed by Lawrence Livermore National Laboratory, the Mod 1 and Mod 2 version of the weapon entered service in 1973, while the enhanced radiation ("neutron bomb") Mod 3 weapon entered service in 1981.

UK nuclear weapons are moved by road, but movements of US nuclear weapons are conducted by air. The RAF maintains response teams at a number of bases along the flight route which are brought to immediate readiness during the transit of the aircraft through their area. The Special Safety Cell (SSC) at Ensleigh in Bath is staffed throughout the ...
