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 ...
As of 1993, worldwide, 520 atmospheric nuclear explosions (including eight underwater) have been conducted with a total yield of 545 megatons (Mt): 217 Mt from pure fission and 328 Mt from bombs using fusion, while the estimated number of underground nuclear tests conducted in the period from 1957 to 1992 is 1,352 explosions with a total yield ...
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.

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 ...
Nuclear bomb damaged in crash [34] During a simulated takeoff, a wheel casting failure caused the tail of a USAF B-47 carrying a Mark 36 Mod 1 nuclear bomb to hit the runway, rupturing a fuel tank and sparking a fire which burned for some 7 hours. [35] The weapon used in-flight insertion and the weapon was in its retracted, unarmed state. [36]
The bomb failed to explode and the transmission line was not badly damaged. [75] [76] The Hanford Engineer Works was the only U.S. nuclear facility to come under enemy attack. [77] Hanford provided the plutonium for the bomb used in the 1945 Trinity nuclear test. [78] Throughout this period, the Manhattan Project maintained a top-secret ...
The first test, known as the Salmon Event, took place on October 22, 1964. [2] It involved detonation of a 5.3 kiloton device at a depth of 2,700 feet (820 m). [ 3 ] The second test, known as the Sterling Event, took place on December 3, 1966 and involved detonation of a 380-ton device suspended in the cavity left by the previous test. [ 2 ]
