Russia Releases Footage Of A 100 Megaton Nuke Test From 1961
2020-08-26
[Zero Hedge] - Russia has for the first time released full declassified footage of the Soviet Union's monster nuclear bomb known as the 'Tsar Bomba' hydrogen bomb (codenamed "Ivan").

Widely considered to be the most powerful nuclear weapon ever created and tested, it was detonated 4,000 meters above a sparsely populated archipelago in the Barents Sea on Oct. 30, 1961 as part of a secretive test nevertheless detected by US intelligence.

The bomb had a yield of an estimated 50 megatons, or the equivalent of 50 million tons of TNT, and though poor-quality images had already been released, just days ago the Rosatom State Atomic Energy Corporation published a 40-minute full documentary featuring the new declassified video of the bomb detonation after being dropped by a Tu-95 Bear bomber on the occasion of the 75th anniversary of Russia’s nuclear industry.
I'm wondering what that test site looks like now.

#9  The 'covert' Soviet test ended up not being so secret after all, given reports say the blast and resulting mushroom cloud were visible up to 621 miles away, further shattering windows in nearby Finland.

No shit Sherlock

#8  Apparently the design allowed for a final fast fission stage.

The very fast neutrons emitted by fusion stage would have triggered fission of U238 which would have contributed the other 50 megatons, at the price of massive contamination with radioactive fission products.

Since they would have used depleted or natural uranium critical mass wouldn't have been an issue.

#7  I looked at one of the other related Youtube videos - the British guy said Sakharov inserted lead for half of the uranium charge ball (or whatever it's called) and that led to the nuke yield dropping from 100 megatons to 50.

Megaton - now that's a heavy metal band name if I ever heard one.

#6  Today, it looks out of focus, or intentionally blurred. Satellite

#5  Raj, I believe Severny Island is pretty much back to normal now.

Except for appearing in a Larry Correia book, that is.

#4  As for the bomb's yield:

"The initial three-stage design (coded A620EN, not tested) was capable of yielding approximately 100 Mt (420 PJ) through fast fission, 3,000 times the size of the Hiroshima and Nagasaki bombs,[23] but it was thought that it would have caused too much nuclear fallout and the aircraft delivering the bomb would not have had enough time to escape the explosion."

#3  Severny Island

The bomb was detonated 4,000 metres (13,000 ft) above the Sukhoy Nos ("Dry Nose") cape of Severny Island

Fascinating story

#2  According to legend, Khrushchev wanted a 100 MT explosion but the military, scientists and engineers involved cut it back for safety reasons.

#1  Correction - it was estimated at 50 megatons; coulda sworn I saw 100 megatons somewhere in the article. Still...
