Operation Project 58/58A [1] was a series of 4 nuclear tests conducted by the United States in 1957–1958 at the Nevada Test Site. These tests followed the Operation Plumbbob series and preceded the Operation Hardtack I series. All the tests in Project 58 were one-point safety tests. [2]
The United States's Aqueduct nuclear test series [1] was a group of 10 nuclear tests conducted in 1989–1990. These tests [ note 1 ] followed the Operation Cornerstone series and preceded the Operation Sculpin series.
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 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.
English: This is the official list of questions (and expected answers) that can be asked on the civics portion of the American naturalization test, revised in January of 2019. While most of these questions are supplied with answers, the ones that ask about specific members of the American government are not.
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 ).
If there is any nuclear yield in the firing, then the test is deemed a failure from a safety standpoint. A successful test will measure only the chemical explosive in the test bomb exploding, which still, of course, blasts the bomb core and causes the core material to be spread over a wide area if the test is in open air, as all the Project 56 ...
