  2. High-altitude nuclear explosion - Wikipedia

    en.wikipedia.org/.../High-altitude_nuclear_explosion

    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 Partial Test Ban Treaty was passed in October 1963, ending atmospheric and ...

    en.wikipedia.org/wiki/Starfish_Prime

    The flash created by the explosion as seen through heavy cloud cover from Honolulu, 900 miles (1,450 km) away. Starfish Prime was a high-altitude nuclear test conducted by the United States, a joint effort of the Atomic Energy Commission (AEC) and the Defense Atomic Support Agency. It was launched from Johnston Atoll on July 9, 1962, and was ...

  4. Nuclear electromagnetic pulse - Wikipedia

    en.wikipedia.org/wiki/Nuclear_electromagnetic_pulse

    In nuclear EMP all of the components of the electromagnetic pulse are generated outside of the weapon. [33] For high-altitude nuclear explosions, much of the EMP is generated far from the detonation (where the gamma radiation from the explosion hits the upper atmosphere). This electric field from the EMP is remarkably uniform over the large ...

  5. Effects of nuclear explosions - Wikipedia

    en.wikipedia.org/wiki/Effects_of_nuclear_explosions

    For high altitude nuclear explosions, these electrons are captured in the Earth's magnetic field at altitudes between 20 and 40 kilometers where they interact with the Earth's magnetic field to produce a coherent nuclear electromagnetic pulse (NEMP) which lasts about one millisecond. Secondary effects may last for more than a second.

  6. Operation Fishbowl - Wikipedia

    en.wikipedia.org/wiki/Operation_Fishbowl

    The United States completed six high-altitude nuclear tests in 1958, but the high-altitude tests of that year raised a number of questions. According to U.S. Government Report ADA955694 on the first successful test of the Fishbowl series, "Previous high-altitude nuclear tests: Teak, Orange, and Yucca, plus the three ARGUS shots were poorly instrumented and hastily executed.

  7. Operation Hardtack I - Wikipedia

    en.wikipedia.org/wiki/Operation_Hardtack_I

    High-altitude tests. Operation Hardtack I contained three high-altitude tests called Operation Newsreel that were designed to study many effects that a nuclear explosion would have on materials and electronic systems. They were also used to test the energy of the explosion and what forms of energy they would produce.

  8. Operation Argus - Wikipedia

    en.wikipedia.org/wiki/Operation_Argus

    Operation Argus was a series of United States low-yield, high-altitude nuclear weapons tests and missile tests secretly conducted from 27 August to 9 September 1958 over the South Atlantic Ocean. [1][2] The tests were performed by the Defense Nuclear Agency. The tests were to study the Christofilos effect, which suggested it was possible to ...
