Russia Releases "Tsar Bomba" Test Footage Of The Most Powerful Nuclear Bomb Blast Ever

The nuclear bomb, codenamed "Ivan," that was dropped by the Soviet Union over Novaya Zemlya in the Arctic Ocean on October 30, 1961, was the largest device of its kind ever detonated. The monstrous weapon had a yield of around 50 megatons — equivalent to 50 million tons of TNT. Until now, the available imagery of that test has been strictly limited, consisting of short, grainy clips and poor-quality stills.

The colossal Ivan device was developed under a program known as izdeliye 202 (meaning "product 202", otherwise known simply as "V"). Years later, when more details became known about it in the West, the weapon would be dubbed "Tsar Bomba."

On August 20, 2020, the Rosatom State Atomic Energy Corporation — the Russian state concern responsible for nuclear enterprises, including nuclear weapons — released a 30-minute documentary film on its official YouTube channel showing the test in unprecedented detail, from the initial transport of the device itself to the mushroom cloud that later rose some 6.2 miles over the Arctic archipelago. The release of the film coincides with the 75th anniversary of Russia's nuclear industry — although a thermonuclear bomb popularly described in the West as a "doomsday weapon" was perhaps an unusual choice for the commemoration. Regardless, it was a remarkable technological achievement.

    It was probably decided for one reason or another, on the other hand do you want to be the one to tell Comrade Stalin that the weather was a little bad so you decided to postpone the bomb test. Plus they probably figured it would be bright enough at detonation that the weather might not matter all that much. It was probably insignificant compared to what was about to happen, or I guess they just liked it cloudy.

    I somehow think how it would look on youtube in 60 years time was the least of their worries.

      Which would explain why they only recorded in 480p, no HD or anything. Very inconsiderate.

    The low impact is a direct result of the square/cube law. 10x the force doesn't mean 10x the destruction. The stuff in the center, so what if it's destroyed 10x more - destroyed is destroyed. And most of the energy goes up since it's not in an enclosed space, so the old rule of thumb was 10x the force = 2x the damage. That's what makes MIRVs so attractive. Much more bang for the buck, and defences probably won't get all of them. And to be really nasty, give some of them the same characteristics of decoys so they sneak through.

      I'm fairly sure your facts are bullshit and you smoke Kool Aid based on the circle/sphere law. 2x is 10x.
