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]
High-altitude nuclear explosions are the result of nuclear weapons testing within the upper layers of the Earth's atmosphere and in outer space. Several such tests were performed at high altitudes by the United States and the Soviet Union between 1958 and 1962.
The Nevada National Security Sites (N2S2 [1] or NNSS), popularized as the Nevada Test Site (NTS) until 2010, [2] is a reservation of the United States Department of Energy located in the southeastern portion of Nye County, Nevada, about 65 mi (105 km) northwest of the city of Las Vegas.
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 ...
Yucca Flat saw 739 nuclear tests, including 827 separate detonations. The higher number of detonations is from single tests that included multiple nuclear explosions occurring within a 0.1 second time window and inside a 1.2 mi (2 km) diameter circle. Sixty-two such tests took place at NTS. [3]
At the explosion of nuclear bombs lightning discharges sometimes occur. [40] Smoke trails are often seen in photographs of nuclear explosions. These are not from the explosion; they are left by sounding rockets launched just prior to detonation. These trails allow observation of the blast's normally invisible shock wave in the moments following ...
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.
Ground shock, or water shock will result from nuclear explosions on (or near) the surface of ground or water. The ground shock can damage or destroy hardened structures. In water, the shock is damaging to nearby vessels and may also produce a surface wave to limited ranges. A crater is formed by an explosion at (or near) the ground surface.
