With the process understood, the race was on to weaponise it.Ĭynthia C Kelly is founder and president of the Atomic Heritage Foundation, dedicated to the preservation of the Manhattan Project and crucial to having the three sites gain national park status in the US. The prospect of weaponising nuclear fission focused the minds of scientists across Europe, with plutonium and uranium identified as elements that could undergo the process. This was discovered in 1938 by two German scientists, and Oppenheimer realised its destructive potential when word reached him in 1939. Tibbets Jr., commander of the 509th Composite Group, and.

Little Boy was the name of the type of atomic bomb used in the bombing of the Japanese city of Hiroshima on 6 August 1945 during World War II, making it the first nuclear weapon used in warfare. bomb containing a sphere of the metal plutonium 239, it was surrounded by blocks of high explosives that were designed to produce.
