By Tsar Bomba do you mean that gigantic thing the Russians blew off around 1955 the same year we had the two giant hurricanes Hazel and Diane?
Nope. Tsar Bomba is considered the largest air blast every exploded. It was detonated on October 30, 1961 (probably in celebration of the past August's birth of the messiah Obomba somewhere in Kenya) on the Arctic island of Novaya Zemlya. It was 55 to 66 Megatons.
