The blast created a crater 1.9 km (6,230 ft) in diameter and 50 m (164 ft) deep where Elugelab had once been; [24] the blast and water waves from the explosion (some waves up to 6 m (20 ft) high) stripped the test islands clean of vegetation, as observed by a helicopter survey within 60 minutes after the test, by which time the mushroom cloud ...
The first use of "levitated" cores made of oralloy. Tested components for Mark 4 design. Ranger: 1951 5: 5: 5: 1 to 22 40: First tests at the Nevada Test Site. Operation originally named "Operation Faust". Greenhouse: 1951 4: 4: 4: 46 to 225 398: George shot was physics experiment relating to the hydrogen bomb; Item shot was first boosted ...
The Operation Ivy test series was the first to involve a hydrogen bomb rather than an atomic bomb, further to the order of President Harry S. Truman made on January 31, 1950, that the US should continue research into all forms of nuclear weapons.
The Nevada National Security Sites (N2S2 [1] or NNSS), popularized as the Nevada Test Site (NTS) until 2010, [2] is a reservation of the United States Department of Energy located in the southeastern portion of Nye County, Nevada, about 65 mi (105 km) northwest of the city of Las Vegas.
The Ivy Mike shot of 1 November 1952, at Enewetak Atoll, was the first full test of a Teller-Ulam design staged hydrogen bomb, with a yield of 10 megatons. This was not a deployable weapon. With its full cryogenic equipment it weighed about 82 tons. [citation needed]
These tests include 904 at the Nevada Test Site, 106 at the Pacific Proving Grounds and other locations in the Pacific, 3 in the South Atlantic Ocean, and 17 other tests taking place in Amchitka Alaska, Colorado, Mississippi, New Mexico and Nevada outside the NNSS (see Nuclear weapons and the United States for details). 24 tests are classified ...
While British atomic bomb development represented an extraordinary scientific and technological achievement, hopes that the United States would be sufficiently impressed to restore the nuclear Special Relationship were dashed. [15] In November 1952, the United States conducted Ivy Mike, the first successful test of a true thermonuclear device ...
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.
