Replica of most powerful nuclear bomb ever goes on display in Moscow

A mockup of a Soviet AN-602 hydrogen bomb (Tsar Bomb) is displayed at the exhibition devoted to the 70th anniversary of Russia

MOSCOW: Eight metres long and weighing 25 tonnes, a replica of the so-called Tsar Bomb, the most powerful nuclear bomb ever detonated, has gone on display for the first time in Russia, in the midst of an ongoing standoff with the West over Ukraine.

Tested in 1961 by the Soviet Union, the hydrogen bomb -- also known as the AN602 -- instilled a mix of pride and fear in retired military pilot Nikolay Krylov as he looked at the replica housed at an exhibition centre near the Kremlin.
