Ivy Mike was the codename given to the first full-scale [note 1] test of a thermonuclear device, in which a significant fraction of the explosive yield comes from nuclear fusion. [ 1 ] [ 2 ] [ 3 ] Ivy Mike was detonated on November 1, 1952, by the United States on the island of Elugelab in Enewetak Atoll , in the now independent island nation ...
The first test of that series was Castle Bravo, a new design utilizing a dry fuel thermonuclear bomb. It was detonated at dawn on March 1, 1954. It was detonated at dawn on March 1, 1954. The explosion yielded 15 Mt of TNT, far exceeding the expected yield of 4 to 8 Mt of TNT (6 predicted), [ 6 ] and was about 1,000 times more powerful than ...
The first Ivy shot, codenamed Mike, was the first successful full-scale test of a multi-megaton thermonuclear weapon ("hydrogen bomb") using the Teller-Ulam design.Unlike later thermonuclear weapons, Mike used deuterium as its fusion fuel, maintained as a liquid by an expensive and cumbersome cryogenic system.
Castle Bravo was the first in a series of high-yield thermonuclear weapon design tests conducted by the United States at Bikini Atoll, Marshall Islands, as part of Operation Castle. Detonated on March 1, 1954, the device remains the most powerful nuclear device ever detonated by the United States and the first lithium deuteride -fueled ...
The first use of "levitated" cores made of oralloy. Tested components for Mark 4 design. Ranger: 1951 5: 5: 5: 1 to 22 40: First tests at the Nevada Test Site. Operation originally named "Operation Faust". Greenhouse: 1951 4: 4: 4: 46 to 225 398: George shot was physics experiment relating to the hydrogen bomb; Item shot was first boosted ...
Earlier in 1954, a Japanese tuna fishing boat, Daigo Fukuryū Maru ("Lucky Dragon 5") had been exposed to radioactive fallout from the first H-bomb test at Bikini Atoll on March 1. One man died ...
The Ivy Mike test was the world's first "hydrogen bomb", producing a full-scale thermonuclear or fusion explosion. The Ivy Mike device used liquid deuterium , an isotope of hydrogen , making it a "wet" bomb.
