Castle Bravo



Castle Bravo was the code name given to the first U.S. test of a thermonuclear hydrogen bomb device, detonated on March 1, 1954, at Bikini Atoll, Marshall Islands, by the United States. Castle Bravo was the most powerful nuclear device ever detonated by the United States, with a yield of 15 Megatons. That yield, far exceeding the expected yield of 4 to 6 megatons, combined with other factors to produce the worst radiological accident ever caused by the United States.
