Castle Bravo was the largest atomic bomb detonated in the atmosphere by the United States. It was equal to a force nearly a thousand times that of the Hiroshima bomb and created a fireball four miles wide that vaporized the entire test island and parts of two others. Its fallout covered an estimated 7,000 square miles and there was no prior warning of the test for the people in the region (Weingartner 1991:11). Bravo was one of 23 atomic and hydrogen bombs tested by the United States at Bikini Atoll in the Marshall Islands, Micronesia, between 1946 and 1958.
