Project Chariot was a 1958 United States Atomic Energy Commission proposal to construct an artificial harbor at Cape Thompson on the North Slope of the U.S. state of Alaska by burying and detonating a string of nuclear devices.
In 1969, the AEC's relationship with science and the environment was brought to the forefront of a growing public controversy that had been building since 1965. In search for an ideal location for a large-yield nuclear test, the AEC settled upon the island of Amchitka, part of the Aleutian Islands National Wildlife Refuge in Alaska.
Trinity, part of Project Manhattan, was the first ever nuclear explosion. The nuclear weapons tests of the United States were performed from 1945 to 1992 as part of the nuclear arms race. The United States conducted around 1,054 nuclear tests by official count, including 216 atmospheric, underwater, and space tests.
1943 – Laboratory No. 2 is established to pursue nuclear weapons research under Igor Kurchatov. [6] 1943 – March – The Japanese Committee on Research in the Application of Nuclear Physics, chaired by Yoshio Nishina concludes in a report that while an atomic bomb was feasible, it would be unlikely to produce one during the war.
Nuclear program start date: 21 October 1939: First nuclear weapon test: 16 July 1945: First thermonuclear weapon test: 1 November 1952: Last nuclear test: 23 September 1992 [1] Largest yield test: 15 Mt (63 PJ) (1 March 1954) Total tests: 1,054 detonations: Peak stockpile: 31,255 warheads (1967) [2] Current stockpile: 3,708 (2024) [3] Maximum ...
The United States opened the nuclear era in July 1945 with the test of a 20-kiloton atomic bomb at Alamogordo, New Mexico, in July 1945, and then dropped atomic bombs on the Japanese c
The project identified numerous sites in the coterminous United States, Pacific Ocean, Alaska and overseas, narrowing the list to ten locations. In late 1963, the process became Project Larkspur , which selected Amchitka Island as the preferred test site for atmospheric testing, using another Vela Uniform project for underground testing, as cover.
[2] The Atomic Energy Act of 1954 encouraged private corporations to build nuclear reactors and a significant learning phase followed with many early partial core meltdowns and accidents at experimental reactors and research facilities. [3] The Cold War reached the climax in the 1960s, especially the Cuban Missile Crisis in 1962.
