Bikini Atoll is one of 29 atolls and five islands that make up the Marshall Islands (“A Short History”). Located in Micronesia, Bikini Atoll played a major role in World War II. Originally taken by the Japanese and used as a lookout point, it was later captured by U.S. forces in a battle that took place in its neighboring Kwajalein Atoll (“A Short History”). This would crush the Japanese hold on the Marshall Islands. After the war, President Truman recognized the importance of the Marshall Islands and its location in the Pacific. The Truman Administration wanted to enhance the countries knowledge on the effects of nuclear weapons on its ships and equipment. Until that point, nuclear testing was done on the behavior of nuclear weapons.
During the summer of 1946, a joint task force was given the mission to test the effects of nuclear radiation on ships, equipment and material. Formed in the winter of 1946, Joint Task Force 1 was made up of Navy, Army and civilian personnel (“Operation Crossroads, 1946”). The test was done using two atomic bombs, ABLE and BAKER. The target, was a fleet of 71 to 90 ships, depending on the source, and was made up of older U.S. ships and captured German and Japanese ships the first detonation in the series was named ABLE. ABLE was a 23 kt air burst that would fall short and to the left of its target resulting in only 5 ships being destroyed (“Operation Crossroads”). Experts determined the radiation was low enough to only require a couple of days before a crew could board the vessels and do their research. The BAKER detonation would be a similar weapon with only slight modifications to allow it to be suspended underwater. Anchored to the LSM-60, a landing ship, the BAKER detonation would test the effec...
