Tsar Bomba, Biggest Nuke Ever!

Tsar Bomba is the Western name for the RDS-220, which was the largest, most powerful nuclear weapon ever detonated. Developed by the Soviet Union, the bomb had a yield of about 50 megatons of TNT and it was codenamed Ivan by its developers.

The bomb was tested on October 30, 1961, in Novaya Zemlya, an archipelago in the Arctic Sea. The device was scaled down from its original design of 100 megatons to reduce the resulting nuclear fallout.
