Between 1946 and 1955, the United States conducted a series of underwater nuclear tests—many at Bikini Atoll—to study the effects of atomic blasts on naval vessels and submarines. ☢️ These tests advanced the development of nuclear torpedoes and deepened scientific understanding of underwater explosions and radiation in marine environments. Due to the serious contamination risks they posed, underwater nuclear tests were later banned under the 1963 Partial Test Ban Treaty. #NuclearHistory #AtomicH
