World’s First Underwater Nuclear Explosion

In in 1946, the United States conducted a series of nuclear weapon tests at Bikini Atoll in what’s known as Operation Crossroads. A total of two bombs were detonated to test the effects nuclear blasts had on naval warships. The second, named Baker, was the world’s first nuke to be detonated underwater. Due to the unique properties of underwater explosions, the Baker test produced a number of unique photographs that the world had never seen before. The blast lifted two million tons of water and sand into the air, creating a column 6,000 feet tall, 2,000 feet wide, and with walls 300 feet thick.
