The Tsar Bomba was the culmination of a series of high-yield thermonuclear weapons designed by the Soviet Union and the United States during the 1950s (examples include the Mark-17 and B41).one of total destruction of the Tsar Bomba (as an example â over a map of Paris): red circle = total destruction (radius 35 kilometres (22 mi)), yellow circle = fireball (radius 3.5 kilometres (2.2 mi)).
Tsar Bomba (Russian language: ÑÐ°ÑÑ-Ð±Ð¾Ð¼Ð±Ð°; Tsar Bomb) 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.ence, the Tsar Bomba was an impractically powerful weapon. It was decided that a full 100 Mt detonation would create too great a risk of nuclear fallout, as well as a near certainty that the release plane (and crew) would be destroyed before it could escape the blast radius.
