The nuclear explosion was carried out in open ocean outside of Enewetak. This nuclear test codenamed Wahoo was the first underwater test in the Operation Hardtack series. This test could be considered a continuation of the Wigwam nuclear blast (a deep water nuclear test 500 nautical miles (930 km; 580 mi) off the coast of San Diego). [9]
Operation Wigwam[ 1 ] involved a single test of the Mark 90 "Betty" nuclear bomb. It was conducted between Operation Teapot and Project 56 on May 14, 1955, about 500 miles (800 km) southwest of San Diego, California. 6,800 personnel aboard 30 ships were involved in Wigwam. The purpose of Wigwam was to determine the vulnerability of submarines ...
Test information. Nuclear tests. 105. The Pacific Proving Grounds was the name given by the United States government to a number of sites in the Marshall Islands and a few other sites in the Pacific Ocean at which it conducted nuclear testing between 1946 and 1962. The U.S. tested a nuclear weapon (codenamed Able) on Bikini Atoll on June 30, 1946.
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] The test weapons produced a combined yield of about 77 Mt of TNT in ...
Operation Ivy was the eighth series of American nuclear tests, ... The detonation left an underwater crater 6,240 ft (1.9 km) wide and 164 ft (50 m) deep where ...
Sandstone →. 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 ...
Twenty years earlier in 1959, the USSR had conducted secret underwater tests in the Pacific in violation of the 1958 bilateral moratorium between the Soviet Union and the U.S. (cf. List of nuclear weapons tests of the Soviet Union) [48] [49] [50] before the 1958 moratorium was unilaterally and officially abrogated by the Soviet Union in 1961.
Underground nuclear testing is the test detonation of nuclear weapons that is performed underground. When the device being tested is buried at sufficient depth, the nuclear explosion may be contained, with no release of radioactive materials to the atmosphere. The extreme heat and pressure of an underground nuclear explosion causes changes in ...
