Already subjected to a series of nuclear weapons tests as host to Operation Crossroads (see previously, see also), on this day in 1954 the United States conducted the first in the battery of design experiments with Operation Castle, detonating the a high yield thermonuclear, fusion bomb on an artificial island platform in the lagoon of Namu in the Bikini Atoll of the Marshall Islands. The strongest tactile explosion in history, the bomb was more than one-thousand times stronger than those dropped on Hiroshima and Nagasaki, exceeding expectations of developers and spreading fallout (the heaviest in the form of pulverised and irradiated coral) across the region and far beyond. Residents were not evacuated and the decision was made not to abort the test despite wind shear that imperilled the islanders as well as personnel involved in the research. Trace amounts of radioactive material detected as far away as Australia, Europe and North America turned Castle Bravo into an international incident, prompting worldwide monitoring of fallout levels and a ban on further atmospheric tests.
