Mockup of biggest ever nuke exhibited in Rusia

The life-size replica of the largest nuclear bomb ever detonated in history, the so-called Tsar Bomba, is on display for the first time in an exhibition in the Russian capital, Moscow.

The historical exhibition, open from September 1-29 at the Manege Exhibition Hall in Red Square, is to celebrate the 70th anniversary of Russian atomic development.

According to the organizers of the exhibition, the main highlight of the event is to display a copy of the thermonuclear bomb.

Weighing 25 tones, the eight-meter long hydrogen bomb – also known as the AN602- was designed by the Soviet Union and was tested on October 30, 1961, in the midst of the Cold War.

Tsar Bomba was detonated over the Mityushikha Bay nuclear testing range, north of the Arctic Circle over Novaya Zemlya archipelago in the Arctic Sea.

It was dropped from an altitude of 10.5 kilometers and was designed to detonate at a height of 4 kilometers over the land surface.

The explosive energy released by AN602, some 57 megaton TNT, exceeded 3,800 times the Fat Man nuclear bomb, which was dropped and detonated on Nagasaki, Japan, by the United States on August 9, 1945. Its energy also surpassed the combined power of all explosives used by all countries during the Second World War.

The blast wave went round the Earth three times and for about 40 minutes after the detonation radio signal distortions were recorded hundreds of kilometers from the epicenter.
