Operation Fishbowl was a series of high-altitude nuclear tests in 1962 that were carried out by the United States as a part of the larger ''Operation Dominic'' nuclear test program. ==Introduction== The ''Operation Fishbowl'' nuclear tests were originally planned to be completed during the first half of 1962 with three tests named ''Bluegill, Starfish'' and ''Urraca''. The first test attempt was delayed until June. Planning for ''Operation Fishbowl'', as well as many other nuclear tests in the region, was begun rapidly in response to the sudden Soviet announcement on 30 August 1961 that they were ending a three-year moratorium on nuclear testing.〔(【引用サイトリンク】url=http://nuclearweaponarchive.org/Usa/Tests/Dominic.html )〕 The rapid planning of very complex operations necessitated many changes as the project progressed. All of the tests were to be launched on missiles from Johnston Island in the Pacific Ocean north of the equator. Johnston Island had already been established as a launch site for United States high-altitude nuclear tests, rather than the other locations in the Pacific Proving Grounds. In 1958, Lewis Strauss, then chairman of the United States Atomic Energy Commission, opposed doing any high-altitude tests at locations that had been used for earlier Pacific nuclear tests. His opposition was because of fears that the flash from the nighttime high-altitude detonations might blind civilians who were living on nearby islands. Johnston Island was a remote location, more distant from populated areas than other potential test locations.〔''Defense's Nuclear Agency 1947–1997''. Page 139. Defense Threat Reduction Agency, 2002 ()〕 In order to protect residents of the Hawaiian Islands from flash blindness or permanent retinal injury from the bright nuclear flash, the nuclear missiles of ''Operation Fishbowl'' were launched generally toward the southwest of Johnston Island so that the detonations would be farther from Hawaii. ''Urraca'' was to be a test of about 1 megaton yield at very high altitude (above 1000 km.).〔Conrad, Edward E., et al. "Collateral Damage to Satellites from an EMP Attack" Report DTRA-IR-10-22, Defense Threat Reduction Agency. August 2010 () (Retrieved 2014-01-20)〕 The proposed ''Urraca'' test was always controversial, especially after the damage caused to satellites by the ''Starfish Prime'' detonation, as described below. ''Urraca'' was finally canceled, and an extensive re-evaluation of the ''Operation Fishbowl'' plan was made during an 82-day operations pause after the ''Bluegill Prime'' disaster of 25 July 1962, as described below. A test named ''Kingfish'' was added during the early stages of ''Operation Fishbowl'' planning. Two low-yield tests, ''Checkmate'' and ''Tightrope'', were also added during the project, so the final number of tests in ''Operation Fishbowl'' were five. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Operation Fishbowl」の詳細全文を読む スポンサード リンク
