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 ...
Unlike later thermonuclear weapons, Mike used deuterium as its fusion fuel, maintained as a liquid by an expensive and cumbersome cryogenic system. The bomb was detonated on November 1, 1952, on Elugelab Island yielding 10.4 megatons, almost 500 times the yield of the bomb dropped on Nagasaki, resulting in the total vaporization of the island ...
The first nuclear device was detonated as a test by the United States at the Trinity site in New Mexico on July 16, 1945, with a yield approximately equivalent to 20 kilotons of TNT. The first thermonuclear weapon technology test of an engineered device, codenamed Ivy Mike , was tested at the Enewetak Atoll in the Marshall Islands on November 1 ...
The 1954 test shot Nectar of Operation Castle produced a yield of 1.69 megatons and was detonated just North East of Ivy Mike's Elugelab crater, off the coast of Teiter (Gene) Island. The Island of Bogon/Bokon (Irene), is the spearhead-shaped object at the bottom right of the screen.
The successful test rendered obsolete the cryogenic design used by Ivy Mike and its weaponized derivative, the JUGHEAD, which was slated to be tested as the initial Castle Yankee. It also used a 3.7-inch-thick (9.5 cm) 7075 aluminum ballistic case. Aluminum was used to drastically reduce the bomb's weight and simultaneously provided sufficient ...
Two weapons were detonated at the Enewetak Atoll as part of Operation Ivy in 1952. One of them, Ivy King, was the largest pure-fission bomb ever detonated, with a yield of 500 kilotons, [12] and the other, Ivy Mike, was the first hydrogen bomb device (it was too large to be an actual weapon), with a yield of 10.4 Mt.
Test shot Nectar of Operation Castle produced a yield of 1.69 megatons and was detonated just north east of Ivy Mike's Elugelab crater. The Island of Bogon is the spearhead shaped object at the bottom right of the screen, as it was before the Redwing Seminole test was conducted on that island.
The United States' first thermonuclear weapon, Ivy Mike, was detonated on 1 November 1952 at Enewetak Atoll and yielded 10 Megatons of explosive force. The first thermonuclear weapon tested by the USSR, RDS-6s (Joe-4), was detonated on August 12, 1953, at the Semipalatinsk Test Site in Kazakhstan and yielded about 400 kilotons. [7]
