Orbital kinetic energy of the Parker Solar Probe as it dives deep into the Sun's gravity well in December 2024, reaching a peak velocity of 430,000 mph. [172] [173] [174] 6.3×10 13 J: Yield of the Little Boy atomic bomb dropped on Hiroshima in World War II (15 kilotons) [175] [176] 9×10 13 J: Theoretical total mass–energy of 1 gram of ...
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 ...
"Compared with other nuclear events: The Chernobyl explosion put 400 times more radioactive material into the Earth's atmosphere than the atomic bomb dropped on Hiroshima; atomic weapons tests conducted in the 1950s and 1960s all together are estimated to have put some 100 to 1,000 times more radioactive material into the atmosphere than the ...
A similar chart focusing solely on quantity of warheads in the multi-megaton range is also available. [17] Moreover, total deployed US & "Russian" strategic weapons increased steadily from the 1980s until the Cold War ended. [18] The United States nuclear stockpile increased rapidly from 1945, peaked in 1966, and declined after that. [1]
[55] [56] In January 2016, North Korea claimed to have successfully tested a hydrogen bomb, [57] although only a magnitude 5.1 seismic event was detected at the time of the test, [58] a similar magnitude to the 2013 test of a 6–9 kt (25–38 TJ) atomic bomb. These seismic recordings cast doubt upon North Korea's claim that a hydrogen bomb was ...
Despite the lethal radiation and blast zone extending well past her position at Hiroshima, [55] Takakura survived the effects of a 16 kt atomic bomb at a distance of 300 metres (980 ft) from the hypocenter, with only minor injuries, due mainly to her position in the lobby of the Bank of Japan, a reinforced concrete building, at the time.
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
Yellow Sun was the first British operational high-yield strategic nuclear weapon warhead. The name refers only to the outer casing; the warhead (or physics package) was known as "Green Grass" in Yellow Sun Mk.1 and "Red Snow" (a US design) in Yellow Sun Mk.2. Yellow Sun was designed to contain a variety of warheads.
