TSAR BOMB RUSSIAN BIGGEST NUCLEAR WEAPON 57,000,000 TONS

Tsar Bomba (Царь-бомба), literally “Emperor Bomb“, is the Western name for the RDS-220 hydrogen bomb (codenamed “Иван“ (Ivan) by its developers) — the largest, most powerful nuclear weapon ever detonated. Developed by the Soviet Union, the bomb was originally designed to have a yield of about 100 megatons of TNT; however that was reduced by half in order to limit the amount of nuclear fallout that would result. Two bombs were built, a mock bomb and the real bomb, with the real bomb being tested on October 3
