The Most Powerful Nuclear Bomb

The Most Powerful Nuclear Bomb


The Tsar Bomba was the most powerful nuclear weapon ever created and tested. The blast was more powerful than 50 million tons of TNT and was felt hundreds of miles away.

In October 1961, the Soviet Union dropped the most powerful nuclear bomb in history over a remote island north of the Arctic Circle. Though the bomb detonated nearly 2.5 miles (4 kilometers) above ground, the resulting shockwave stripped the island as bare and flat as a skating rink. Onlookers saw the flash more than 600 miles (965 km) away and felt its incredible heat within 160 miles (250 km) of Ground Zero. The bomb's gargantuan mushroom cloud climbed to just below the edge of space.

This was RDS-220 also known as the Tsar Bomba. Nearly 60 years after the bomb's record-shattering detonation, no single explosive device has come close to matching its destructive power. Last week, Rosatom State Atomic Energy Corporation (Russia's state atomic agency) released 40 minutes of previously classified footage, showing the bomb's journey from manufacturer to mushroom cloud.

Soviet Premier Nikita Khrushchev personally commissioned the construction of the Tsar Bomba in July 1961, Popular Mechanics reported. While Krushchev wanted a 100-megaton nuclear weapon, engineers ultimately presented him with a 50-megaton version — equivalent to 50 million tons (45 million metric tons) of TNT detonated at once. Even with half of the premier's requested payload, the bomb was unfathomably powerful. The bomb was thousands of times stronger than the nukes detonated by the United States over Hiroshima and Nagasaki during World War II, and dwarfed the detonation of Castle Bravo — the most powerful nuclear weapon ever tested by the United States — which yielded just 15 megatons (13 million metric tons).
