Manhattan Project scientists had identified two fissile isotopes for potential use in bombs: uranium-235 and plutonium-239. [7] Uranium-235 became the basis of the Little Boy bomb design, first used (without prior testing) in the bombing of Hiroshima ; the design used in the Trinity test, and eventually used in the bombing of Nagasaki ( Fat Man ...

The Manhattan Project was a research and development project that produced the first atomic bombs during World War II. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the US Army Corps of Engineers. The Army component of ...
Theodore Hall was a spy who had worked on the development of the plutonium bomb the US dropped in Japan. [17] Hall provided the specifications of the bomb dropped on Nagasaki. This information allowed the Soviet scientists a first-hand look at the setup of a successful atomic weapon built by the Manhattan Project.
The Dayton Project was a research and development project to produce polonium during World War II, as part of the larger Manhattan Project to build the first atomic bombs. Work took place at several sites in and around Dayton, Ohio .
