Castle Bravo
Bikini Atoll explosion
Castle Bravo was a U.S. nuclear test conducted in 1954 at Bikini Atoll, the largest American nuclear detonation ever.
The blast yielded fifteen megatons—roughly a thousand times the Hiroshima bomb—far exceeding predictions.
Radioactive fallout contaminated nearby islands and a Japanese fishing vessel, causing international outcry and accelerating global awareness of nuclear dangers.
