Approximately 250 of the third 'American nuclear test film' that has been declassified for more than 55 years will be released on YouTube

Approximately 250 new films of nuclear tests conducted by the United States from 1945 to 1962 have been released on YouTube. These films were excavated and restored after the declassification for about 55 years, and they were first released in March 2017 and the third following the second in December of the same year. It has become.

The new video was released by Lawrence Livermore National Laboratory (LLNL), which was originally established in the United States for the development of nuclear weapons and is now conducting research on various energies and biotechnology. After 750 films were declassified in 2017, LLNL released 64 videos in March of the same year and 62 videos on the YouTube channel in December of the same year.

And LLNL released about 250 new videos on July 4, 2018, US time. It includes the same experimental footage that has been released so far, but it seems that all of them are 'new footage' taken with different cameras.

This video shows the third nuclear explosion 'Tesla' of Operation Teapot, which was carried out at the Nevada National Security Site in 1955. With the film shot at an ultra-high speed of 2400 frames per second, the fireball swells and spreads like a living thing, and even the shock wave that hits the ground bounces off and changes the shape of the fireball. I am.

This is a long-distance capture of the same 'Tesla' explosion. The explosion was unclear due to the experiment conducted around 5 am, and the fireball was not captured very large, but you can see that the smoke generated after the explosion was stretched for a long time by the wind.

This is the state of the experiment 'Redwood' carried out during Operation Hardtack I in 1958. In an experiment conducted at Bikini Atoll in the Pacific Ocean, the appearance of a huge fireball over the clouds makes us feel the 'end of the world'.

This is also the state of the redwood explosion. You can clearly see how the mushroom cloud rises high in the sky.

Similarly, 'Poplar' from 'Operation Hardtack I'. The pattern that remains on the surface of the disappearing fireball is eerie.

'Juniper' from 'Operation Hardtack I'. Looking at the spreading clouds, the words 'Humanity has obtained something that should not be obtained ...' came to my mind naturally.

This is one of the experiments conducted in 'Operation Hardtack II' following 'Operation Hardtack I', 'Langer'. I used a balloon to lift a nuclear bomb and detonate it, but it became a small explosion due to an incomplete explosion.

'Sanford' experiment in the same Hardtack II operation. A mushroom cloud rises after a dazzling flash of light.

The state of 'Danny Boy', one of Operation Nougat from 1961 to 1987, which was the first underground nuclear test. The enormous energy of a nuclear explosion shows a tremendous amount of soil being blown from beneath the ground.

Some of them are not reproduced properly like this, but it seems that LLNL's intention to leave the film as 'material' can be felt.
