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.
"Frigate Bird" was the only operational test of a missile "mated" with a live warhead. Series also included three high-altitude tests known as Operation Fishbowl, separated out in this text. Fishbowl: 1962 9: 9: 4: 9: 400 to 1,400 2,205: The high altitude rocket part of Operation Dominic. Included several failed tests as the rockets failed for ...
The Starfish test was originally planned as the second in the Fishbowl series, but the first launch was lost by the radar tracking equipment and had to be destroyed in flight. [4]: 247 The initial Starfish launch attempt on June 20 was also aborted in flight, this time due to failure of the Thor launch vehicle. The Thor missile flew a normal ...
The specific characteristics of a particular nuclear EMP event vary according to a number of factors, the most important of which is the altitude of the detonation. The term "electromagnetic pulse" generally excludes optical (infrared, visible, ultraviolet) and ionizing (such as X-ray and gamma radiation) ranges.
The charged particles resulting from the blast are accelerated along the Earth's magnetic field lines to create an auroral display at the conjugate point, [2] which has led documentary maker Peter Kuran to characterize these detonations as 'the rainbow bombs'. The visual effects of a high-altitude or space-based explosion may last longer than ...
Little Feller I was the last near-ground atmospheric nuclear detonation conducted by the United States [1] (the high altitude Fishbowl tests concluded in November 1962 with a detonation at around 69,000 feet (21 km) altitude). All further tests were conducted underground, in accordance with the Partial Test Ban Treaty.
Strong links, at least in US nuclear weapons, are always implemented as electro-mechanical systems such as motor-driven switches. [2] There are two main requirements: when functional, never to allow an invalid signals to penetrate the energy barrier, and never to fail in a way that can pass a signal though the barrier before the weak links inside the exclusion zone have also failed.
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 ]
