USA Tests Its Biggest Nuclear Weapon

This Week in History

The USA explodes a huge hydrogen bomb at Bikini Atoll in the Pacific Ocean.

In 1954, the USA tested a massive hydrogen bomb nicknamed "Bravo" at Bikini Atoll, part of the Marshall Islands in the Pacific Ocean. The bomb was nearly 1,000 times more powerful than the atomic bombs the USA dropped on two Japanese cities during World War 2. Three weeks after the test, it was revealed that a Japanese fishing boat was within 80 miles (129 km) of the test-zone during the explosion and that its 23 crew members were seriously affected by radiation sickness. They were among 264 people accidentally exposed to the bomb's radioactive fallout.
