US Government Releases Previously Unseen Videos of Secret Nuclear Weapon Tests

Footage of hundreds of secret nuclear tests carried out during the Cold War has been declassified by the US government for the first time and placed on YouTube.

Between 1945 and 1962, the country carried out 210 nuclear tests in the Mojave desert in Nevada and on several isolated islands in the Pacific.

Concerns about nuclear fallout eventually forced them to carry out the tests either underground or high up in the atmosphere. But as Cold War tensions rose with the Soviet Union, an arms race developed between the two superpowers as they attempted to build bigger, more deadly weapons.

The American nuclear blasts were filmed on high-speed cameras – which could capture each event at around 2,400 frames per second.
