The final test of Operation Fishbowl was detonated at 2130 (9:30 p.m. local Johnston Island time) on 3 November 1962 (the time and date was officially recorded as 0730 UTC, 4 November 1962). It was launched on a Nike-Hercules missile, and detonated at a lower altitude than the other Fishbowl tests. Although it was officially one of the Operation Fishbowl tests, it is sometimes not listed among high-altitude nuclear tests because of its lower detonation altitude. The nuclear yield was reported in most official documents only as being less than 20 kilotons.Read more
