One of the most chilling sites of the 20th century, the mushroom cloud formed by an atomic explosion, it was a site seen frequently at the Bikini Atoll in the republic of the Marshal Islands between 1946 and 1958 when the United States conducted more than 20 nuclear weapons test in the area. Admiral William F. Halsey Jr. or Bull as he was known, overseer operations as he had warship the Independence, was one of those selected as a target vessel for the test, tagged the pacific proving grounds the bomb testing areas saw the first detonation on the 1st of July 1946 in operation crossroads.
The idea of using ships as targets instead of detonating the bombs on land was to see what the effect atomic weapons would have on naval fleets. And the plane carrying the bombs was loaded with livestock including goats, sheep and mice, again to see what effects the blast in resulting radiation would have on the animals.
Unfortunately, the Americans were similarly cavalier in their treatment of the indigenous people in the area. In 1954 Castle Bravo, the US is first drive hydrogen bomb and it's largest weapon ever detonated turned out to be twice as powerful as predicted and cast it's nuclear fall out far and wide. Islands were quickly evacuated, but exposure to radiation left many of them with cancers and abnormally high rates of birth defects. The firth bomb given a Monica Abel had yield of 21 kilo tons and was dropped from an altitude of 158 meters. Surprisingly, Abel didn’t sink the Independence nor did the second test another 21 kilo ton bomb the baker, which was actually designated under water at a depth of 27 meters on the 25th of July 1946.
They can dig course of massive condensation cloud, however, which spread a huge amount of radioactive water on to the ships. The badly contaminated Independence was subject to defer the test at Pear Harbor before finally being scuttled off the coast of San Francisco in 1951.
