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 ...
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 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.
Elugelab, or Elugelap (Marshallese: Āllokļap, [ællʲoɡʷ(o)lˠɑpʲ] [1]), was an island, part of the Enewetak Atoll in the Marshall Islands. It was destroyed in the world's first full-scale thermonuclear explosion, the Mike shot of Operation Ivy, on November 1, 1952.
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.
While the Marshall Islands testing composed 14% of all U.S. tests, it composed nearly 80% of the total yields of those detonated by the U.S., with an estimated total yield of around 210 megatons, with the largest being the 15 Mt Castle Bravo shot of 1954 which spread considerable nuclear fallout on many of the islands, including several that ...
Castle Bravo was the code name given to the first U.S. test of a dry fuel thermonuclear hydrogen bomb device, detonated on March 1, 1954 at Bikini Atoll, Marshall Islands, as the first test of Operation Castle. Fallout from the detonation poisoned the islanders who had previously inhabited the atoll. [1]
