The optimum height of burst to maximize this desired severe ground range destruction for a 1 kt bomb is 0.22 km; for 100 kt, 1 km; and for 10 Mt, 4.7 km. Two distinct, simultaneous phenomena are associated with the blast wave in the air: Static overpressure, i.e., the sharp increase in pressure exerted by the shock wave. The overpressure at any ...
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.
Total weight of nuclear material and bomb was 98.8 - 100.2 kg Hiroshima's "Little Boy" gravity bomb: 13–18 54–75 Gun type uranium-235 fission bomb (the first of the two nuclear weapons that have been used in warfare). 64 kg of Uranium-235, about 1.38% of the uranium fissioned Nagasaki's "Fat Man" gravity bomb 19–23 79–96
Internal nuclear components of the B61 bomb. The bomb was assembled at the Burlington AEC Plant and Pantex. A Sandia document on the dates of the development phases of the US nuclear stockpile describes the B61-3 as an "improved Mod 2 w/IHE" and the B61-4 as "same as Mod 3 ex. Hi-Y". [22] The B61 Mod 3 and 4 bombs do not contain beryllium. [30]
On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki, respectively.The bombings killed between 150,000 and 246,000 people, most of whom were civilians, and they remain the only use of nuclear weapons in an armed conflict.
The Cold War ended in 1991, but the looming threat of nuclear attack lives on with more than 14,900 nuclear weapons wielded by nine nations.. A terrorist-caused nuclear detonation is one of 15 ...
Since the E1 component of nuclear EMP depends on the prompt gamma-ray output, which was only 0.1% of yield in Starfish Prime but can be 0.5% of yield in low-yield pure nuclear fission weapons, a 10 kt (42 TJ) bomb can easily be 5 * 8%= 40% as powerful as the 1.44 Mt (6.0 PJ) Starfish Prime at producing EMP.
The Outer Space Treaty of 1967 banned the stationing of nuclear weapons in space, in addition to other weapons of mass destruction. The Comprehensive Nuclear-Test-Ban Treaty of 1996 prohibits all nuclear testing; whether over- or underground, underwater or in the atmosphere, but hasn't entered into force yet as it hasn't been ratified by some ...
