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.
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.
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.
The operation consisted of 29 explosions, of which only two did not produce any nuclear yield.Twenty-one laboratories and government agencies were involved. While most Operation Plumbbob tests contributed to the development of warheads for intercontinental and intermediate range missiles, they also tested air defense and anti-submarine warheads with smaller yields.
The Army Nuclear Power Program (ANPP) was a program of the United States Army to develop small pressurized water and boiling water nuclear power reactors to generate electrical and space-heating energy primarily at remote, relatively inaccessible sites. The ANPP had several accomplishments, but ultimately it was considered to be "a solution in ...
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 ...
Cannikin was an underground nuclear weapons test performed on November 6, 1971, on Amchitka island, Alaska, by the United States Atomic Energy Commission. [1] The experiment, part of the Operation Grommet nuclear test series, tested the unique W71 warhead design for the LIM-49 Spartan anti-ballistic missile.
[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.
