At 0530, 16 July 1945, in a remote section of the Alamogordo Air Base, New Mexico, the first full scale test was made of the implosion type atomic fission bomb. For the first time in history there was a nuclear explosion. And what an explosion! ... The test was successful beyond the most optimistic expectations of anyone. [152]
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
The Leipzig L-IV experiment accident was the first nuclear accident in history. It occurred on 23 June 1942 in a laboratory at the Physical Institute of the Leipzig University in Leipzig, Germany. There was a steam explosion and a reactor fire in the "uranium machine", a primitive form of research reactor. [1]
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 ...
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.
Shot Argus I of Operation Argus, on 27 August 1958, was the first detonation of a nuclear weapon in outer space when a 1.7-kiloton warhead was detonated at 200 kilometers altitude over the South Atlantic Ocean during a series of high-altitude nuclear explosions.
India's first atomic-test explosion was in 1974 with Smiling Buddha, which it described as a "peaceful nuclear explosion." After the collapse of Eastern Military High Command and the disintegration of Pakistan as a result of the 1971 Winter war, Pakistan's Bhutto launched scientific research on nuclear weapons.
Buster-Jangle Uncle, the first underground nuclear explosion. The first underground nuclear test was conducted on 29 November 1951. [9] [10] [11] This was the 1.2 kiloton Buster-Jangle Uncle, [12] which detonated 17 ft (5.2 m) beneath ground level. [10]
