Newly released and never seen before footage shows the moment the most powerful nuclear weapon ever created being detonated in Russia in the 1960s.

ROSATOM, a Russian state nuclear energy corporation, recently released a classified video footage of the Soviet Union’s 1961 Tsar Bomb test.

It was released to celebrate 75 years of the nuclear industry.

The Tsar Bomba, which means “King of Bombs”, was a really powerful hydrogen bomb that was detonated on October 30, 1961.

It was detonated above the cape of Severny Island in Northern Russia.

In the 40 minute long video that was shared with the public, the listeners are told about the engineering and design behind the bomb before it goes to explode.

The bomb is also known as the Soviet RDS-220.

It is said that the bomb created a fireball 8 kilometers wide, eventually creating a mushroom that soared 64 kilometers up in the sky.

The bomb that we are talking about weighed at 27 tons and measured around 8 meters in length.

To put that in more understandable words, the bomb could not fit the Tu-95V Soviet bomber without some of the fuel tanks being removed.

The bomb that we are talking about had 50 megatons of conventional explosives.

The RDS-220 is believed to be 1,500 times more powerful than the bombs that were dropped on Hiroshima and Nagasaki. That’s combined by the way.

It was also 10 times more powerful than all of the weapons and ammunition that were used in the entire World War II.

The bomb was so powerful that it had to be dropped from a plane with a parachute attached to it to make sure that the crew had enough time to escape the massive explosion.

Despite all the measures, the crew was not sure that they would survive.

The bomb was dropped just 34 miles away from the town of Severny and they had no idea how deadly the bomb drop would be like.

It was reported at that time that buildings in the town, both wooden and brick, were instantly destroyed. Damage of all kinds were reported in Soviet districts hundreds of miles awy from the blast zone.

Some reports also suggested that windows were smashed in some areas of Norway and Finland.
