Minimum 6 kg (12 pounds) of plutonium 239.
The Nagasaki bomb had 14 lb plutonium-239.
approx. 6,2 kg
6.2 kg = 13.7 pounds.
The first plutonium bomb used in the war: Nagasaki (Japan), 9 august 1945 - the "Fat man".
Nuclear bombs made from Plutonium and Uranium.
In an atomic bomb, uranium or plutonium fission or implosive are needed to get the blast. The hydrogen bomb functions by the fusion, or joining together, of lighter elements into heavier elements.
The explosion in Nagasaki was bigger but the damage was less because of the terrain. Fat man, the bomb dropped over Nagasaki was a plutonium implosion type bomb compared with the uranium fission bomb dropped over Hiroshima.
The first Atom Bomb dropped on Hiroshima was called "Little Boy". It weighted about 9,700 pounds and used about 141 pounds of Uranium-235 to generate an explosive blast roughly equal to about 15,000 tons (or 30 million pounds) of conventional TNT explosive. The second Atom Bomb dropped was on Nagasaki. It was called "Fat Man". It weighed about 10,300 pounds and used about 14 pounds of Plutonium-239 & 240 to generate an explosive blast roughly equal to about 21,000 tons (or 42 million pounds) of conventional TNT explosive.
In the Nagasaki bomb, about 14 pounds. Design criteria on later weapons is classified.
Hiroshima bomb: uranium Nagasaki bomb: plutonium
The nuclear bomb A MK-3 Plutonium implosion bomb, it weighed 10,000 pounds and had a 22Kton yield.
Plutonium-239 for Nagasaki's Fat Man Uranium-235 for Hiroshima's Little Boyhydrogen
Plutonium
The Plutonium bomb was nicknamed Fat Man.
It was a plutonium implosion type. So it was an atomic bomb.
Nagasaki (Japan) - 9 August 1945 - a bomb containing 6,4 kg of Plutonium 239
The first plutonium bomb used in the war: Nagasaki (Japan), 9 august 1945 - the "Fat man".
Fat man: Nagasaki, August 1945
The bomb in Hiroshima was plutonium and the Nagasaki was uranium.
It was actually the atom bomb from the Manhattan project. It was dropped on Hiroshima, Japan on August 6, 1945 (that one was a uranium bomb) And dropped on Nagasaki, Japan on August 9, 1945 (a stronger plutonium bomb)
