' coconut place '), [2] known as Eschscholtz Atoll between the 19th century and 1946, [3] is a coral reef in the Marshall Islands consisting of 23 islands surrounding a 229.4-square-mile (594.1 km 2) central lagoon.
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 ]
Operation Crossroads was a pair of nuclear weapon tests conducted by the United States at Bikini Atoll in mid-1946. They were the first nuclear weapon tests since Trinity on July 16, 1945, and the first detonations of nuclear devices since the atomic bombing of Nagasaki on August 9, 1945.
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 1 March 1954, the device remains the most powerful nuclear device ever detonated by the United States and the first lithium deuteride -fueled ...
This was a test conducted at Bikini Atoll to evaluate the effect of the atomic bomb on ships. Captain Stanhope Ring assumed command on 6 March, but was relieved on 2 June by Captain Donald MacMahan. The ship hosted comedian Jack Benny's radio show on 21 April, while Saratoga was berthed in San Francisco before her departure for Bikini. [120]
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 ...
Kili Island or Kili Atoll (Marshallese: Kōle, [1]) is a small, 81 hectares (200 acres) (0.93 square kilometers (0.36 sq mi)) island located in the Marshall Islands in the Pacific Ocean. As of 2021, 415 people lived on the island, [2] many of whom were descended from islanders who originally lived on Bikini Atoll.
Bikini Atoll had previously hosted nuclear testing in 1946 as part of Operation Crossroads where the world's fourth and fifth atomic weapons were detonated in Bikini Lagoon. Since then, American nuclear weapons testing had moved to the Enewetak Atoll to take advantage of generally larger islands and deeper water.
