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. The purpose of the tests was to investigate the effect ...
The first use of the Pacific Proving Grounds was during Operation Crossroads, the first nuclear testing done after the atomic bombing of Hiroshima and Nagasaki. Two fission bombs, both with a yield of 21 kilotons, were tested at Bikini Atoll. "Able" was detonated at an altitude of 520 ft (158 m) on July 1, 1946, and "Baker" was detonated at a ...
Operation Redwing was a United States series of 17 nuclear test detonations from May to July 1956. They were conducted at Bikini and Enewetak atolls by Joint Task Force 7 (JTF7). [1] The entire operation followed Project 56 and preceded Project 57. The primary intention was to test new, second-generation thermonuclear weapons.
The Castle Bravo shot of 1 March 1954, at Bikini Atoll, was the first test of a deployable (solid fuel) thermonuclear weapon, and also (accidentally) [citation needed] the largest weapon ever tested by the United States (15 megatons). It was also the single largest U.S. radiological accident in connection with nuclear testing.
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.
The Baker test during Operation Crossroads, a series of two nuclear weapons tests conducted by the United States at Bikini Atoll.
The nuclear weapons testing at Bikini Atoll program was a series of 23 nuclear devices detonated by the United States between 1946 and 1958 at seven test sites. The test weapons were detonated on the reef itself, on the sea, in the air and underwater [ 22 ] with a combined explosive yield of about 77 Mt .
