Ocean currents, weather conditions, and wind patterns contributed to this spread of fallout and debris. The test was more powerful than scientists predicted. Due to Castle Bravo radioactive debris was released into the atmosphere, and to surrounding atolls. Graves ordered the test to continue as planned. Bravo was the first test of a deliverable hydrogen bomb.ĭespite potential risks, Major General Percy Clarkson and scientific director Dr. Bravo was over 1,000 more times powerful than “Little Boy.” Bravo used a device called “Shrimp” which used lithium deuteride as its fuel.

This was part of Operation Castle, a series of thermonuclear tests. conducted its largest nuclear detonation ever, Castle Bravo, at Bikini Atoll on March 1, 1954. Shot Mike was the first successful hydrogen bomb test. conducted its first series of thermonuclear tests, Operation Ivy, at Enewetak Atoll, in November of 1952. The tests aimed to reduce the overall size of nuclear weapons, including the necessary amount of fissile material, while increasing their destructive power. These were done to test design principles that would later become pivotal in the development of the hydrogen bomb. Operation Greenhouse was a series of nuclear tests conducted at Enewetak Atoll in 1951. research into thermonuclear weapons, which would lead to further U.S. In January of 1950, President Truman made the decision to increase U.S. began a long term project to decontaminate Bikini Atoll.

Operation Crossroads ended on August 10, 1946, due to concerns over radiation, especially to the soldiers involved. nuclear detonations since the “Little Boy” and “Fat Man” bombs dropped over Japan. tested nuclear weapons since the Trinity Test in 1945. These tests were the first time that the U.S. then conducted the Shot Baker test on July 25. They determined that soldiers on ships up to a mile away from this explosion would be instantly be killed. After Shot Able, the Bulletin of the Atomic Scientists confirmed the power of these weapons. Testing in the islands began at Bikini Atoll with the Shot Able test, on July 1, 1946. The purpose of Operation Crossroads was to investigate the effect of nuclear weapons on naval warships. The first testing series in the Marshall Islands occurred under Operation Crossroads. power, contributed to this rapid expansion. Fear of the Soviet Union increasing their atomic weapons, and the belief that building up nuclear arms could help establish U.S. government established the Atomic Energy Commission (AEC) to monitor the peacetime development of atomic science and technology. expanded their nuclear research and development programs. conducted 23 of these tests at Bikini Atoll, and 44 near Enewetak Atoll, but fallout spread throughout the Marshall Islands.ĭuring the post-World War II period the U.S. Between 19, the United States conducted 67 nuclear tests in the Marshall Islands. In 1946, the islands had a population of 52,000. In 1947, the Marshall Islands became part of the Trust Territory of the Pacific Islands, created by the United Nations and then administered by the U.S. planned to test powerful nuclear weapons in the Marshall Islands. Due to the remote location, sparse population, and other nearby U.S.

Marine and Army forces defeated Japanese troops on both the Kwajalein and Enewetak atolls. In 1914, Japan captured the Marshall Islands and built military bases. The Marshallese have lived there for thousands of years. The Marshall Islands have been occupied by humans since the Micronesians arrived in the second millennium BCE. On each atoll there are a number of islands. The Marshall Islands consist of two chains of 29 coral atolls, and are located north of the equator, between Hawaii and Australia.
