The device used in the blast was a 16 kt Mark 5 Nuclear Bomb - a low yield fission weapon, detonated 90 meters / 300 feet above the ground. [2] The live TV coverage was recorded on a kinescope, so it is a rare record of the sound an actual atomic bomb makes. [3] One of the automobiles after the test.
Greenwater, a Lawrence Livermore test, was to be fired in Area 19, [10] and was a test of an x-ray laser system. [12] The test was cancelled 16 July 1992. [13] The Greenwater nuclear device had already been assembled at the time of cancellation, and had to be dismantled. [14] A fourth test, Mighty Uncle, was planned for 1993.
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 the largest nuclear test conducted in outer space, and one of five conducted by the US in space.
The operation consisted of 29 explosions, of which only two did not produce any nuclear yield.Twenty-one laboratories and government agencies were involved. While most Operation Plumbbob tests contributed to the development of warheads for intercontinental and intermediate range missiles, they also tested air defense and anti-submarine warheads with smaller yields.
Operation Ranger was the fourth American nuclear test series. It was conducted in 1951 and was the first series to be carried out at the Nevada Test Site . [ 1 ] All the bombs were dropped by B-50D bombers and exploded in the open air over Frenchman Flat ( Area 5 ).
Operation Hardtack II [1] was a series of 37 nuclear tests conducted by the United States in 1958 at the Nevada Test Site.These tests followed the Operation Argus series and preceded the Operation Nougat series.
The United States's Niblick nuclear test series [1] was a group of 41 nuclear tests conducted in 1963–1964. These tests [ note 1 ] followed the Operation Roller Coaster series and preceded the Operation Whetstone series.
Operation Roller Coaster [1] was a series of four nuclear tests conducted jointly by the United States and the United Kingdom in 1963, at the Nevada Test Site. [2] The tests did not involve the detonation of any nuclear weapons.
