In 1954, a U.S. Air Force B-57B Canberra aircraft filmed Castle Bravo, the most powerful nuclear test ever carried out by the United States. The detonation took place at Bikini Atoll in the Marshall Islands and produced a fifteen megaton explosion that was about one thousand times stronger than the bomb dropped on Hiroshima. The fireball grew several miles wide, and the mushroom cloud rose more than forty miles into the sky. The unexpected strength of the blast spread dangerous radioactive fallo

On March 1, 1954, the United States conducted a secret test that went horrifyingly wrong. The operation was codenamed Castle Bravo. It was the first field test of a deployable "dry" hydrogen bomb, detonated at Bikini Atoll in the Marshall Islands. Scientists expected an explosion of about 6 megatons. They were wrong. Due to a miscalculation in how lithium-7 isotopes would react, the bomb exploded with a yield of 15 megatons—more than 2.5 times larger than predicted. It remains the largest nuclea

“Castle Bravo”, the most powerful nuclear device ever detonated by the US, captured by a B57-B Canberra(1954) flying at 30,000 feet. This was our the first test of a hydrogen bomb by the United States, conducted on March 1, 1954, at Bikini Atoll in the Marshall Islands as part of Operation Castle. It was the most powerful nuclear device ever detonated by the United States and remains infamous for its unexpected scale of destruction and fallout. The weapon was predicted to have a yield of 6 megat

1.4M views · 13K reactions | Castle Bravo, 1954—15 megatons of raw explosive force. The largest U.S. nuclear test ever conducted. What’s wild? That’s the same magnitude as the Tunguska event—a cosmic blast that flattened Siberia in 1908. Nuclear tests gave us more than fallout. They gave us insight into the terrifying power of celestial impacts. | The Randall Carlson | Facebook
