This photo shows the detonation of a U.S. nuclear device codenamed Umbrella, set off on Enewetak Atoll in the Marshall Islands as part of the Hardtack test series, and specifically designed to test radiation contamination on ships exposed to underwater nuclear blasts. The eight kiloton explosion threw a column of water 5,000 feet high, along with whatever unlucky fish, dolphins, and whales happened to be in the vicinity. Just more collateral damage in the ongoing arms race, and certainly not the last. The bomb went off today in 1958.
