It includes nuclear test sites, nuclear combat sites, launch sites for rockets forming part of a nuclear test, and peaceful nuclear test (PNE) sites. There are a few non-nuclear sites included, such as the Degelen Omega chemical blast sites, which are intimately involved with nuclear testing. Listed with each is an approximate location and ...
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.
For nuclear weapon tests, a salvo is defined as two or more underground nuclear explosions conducted at a test site within an area delineated by a circle having a diameter of two kilometers and conducted within a total period of time of 0.1 second.
On this day in 1957, the first underground nuclear test was carried out at the Nevada Test Site, a 1,375 square-mile research center located 65 miles away from Las Vegas. The 1,7 kiloton nuclear ...
In the 1950s and early 1960s, the explosions sent mushroom clouds high into the skies above the New Mexico and Nevada deserts. Testing later was limited to underground explosions, which ended in 1992.
The Alaskan island of Amchitka was initially selected for these tests in 1950, but the site was later deemed unsuitable and the tests were moved to the Nevada Test Site. [8] Buster-Jangle Uncle, the first underground nuclear explosion. The first underground nuclear test was conducted on 29 November 1951.
The site was the primary testing location of American nuclear devices from 1951 to 1992; 928 announced nuclear tests occurred there. Of those, 828 were underground [ 9 ] (62 of the underground tests included multiple, simultaneous nuclear detonations, adding 93 detonations and bringing the total number of NTS nuclear detonations to 1,021, of ...
Nuclear weapons testing did not produce scenarios like nuclear winter as a result of a scenario of a concentrated number of nuclear explosions in a nuclear holocaust, but the thousands of tests, hundreds being atmospheric, did nevertheless produce a global fallout that peaked in 1963 (the bomb pulse), reaching levels of about 0.15 mSv per year ...
