Nuclear testing at Bikini Atoll consisted of the detonation of 23 (or 24 [a]) nuclear weapons by the United States between 1946 and 1958 on Bikini Atoll in the Marshall Islands. Tests occurred at 7 test sites on the reef itself, on the sea, in the air, and underwater. [ 2 ]
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.
Six very large nuclear tests were conducted at the Bikini Atoll and the Enewetak Atoll as part of Operation Castle in 1954. The most notable was Castle Bravo, which was the first deployable (dry fuel) hydrogen bomb developed by the United States. Its yield, at 15 Mt, was over twice as powerful as was predicted, and remains the largest weapon ...
The Tsar Bomba far surpassed the largest explosion the United States has ever conducted - a 15-megaton "Castle Bravo" hydrogen bomb detonated on Bikini Atoll in 1954. (Reporting by Maria Vasilyeva ...
Castle Bravo remains, to this day, the largest detonation ever carried out anywhere by the United States and the fifth largest H-bomb detonation in the world. Because Castle Bravo greatly exceeded its expected yield, JTF-7 was caught unprepared. Much of the permanent infrastructure on Bikini Atoll was heavily damaged.
Redwing demonstrated the first United States airdrop of a deliverable hydrogen bomb during test Cherokee. Because the yields for many tests at Operation Castle in 1954 were dramatically higher than predictions, Redwing was conducted using an "energy budget": There were limits to the total amount of energy released, and the amount of fission ...
Enewetak Atoll, before "Mike" shot. Note island of Elugelab on left. Enewetak Atoll, after "Mike" shot. The crater is on the left. The test was carried out on 1 November 1952 at 07:15 local time (19:15 on 31 October, Greenwich Mean Time). It produced a yield of 10.4 megatons of TNT (44 PJ).
In 1946, a year after the war ended, he watched the first U.S. nuclear bomb tests in Bikini Atoll. He was stationed in Billings, where one of his sisters lived, in 1950. There he was, the man of ...
