Tsar Bomba is the nickname for the AN602 hydrogen bomb, the most powerful nuclear weapon ever detonated.Its October 30, 1961 test remains the most powerful artificial explosion in human history.his attempt was successful, as it was one of the cleanest (relative to its yield) nuclear bombs ever detonated. Only one bomb of this type was ever built and it was tested on October 30, 1961, in the Novaya Zemlya archipelago, at Sukhoy Nos. http://en.wikipedia.org/wiki/Tsar_Bomba.
