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 ...
The impracticability of a gun-type bomb using plutonium was agreed at a meeting held on 17 July 1944. All gun-type work in the Manhattan Project was directed at the Little Boy enriched uranium gun design, and almost all of the research at the Los Alamos Laboratory was re-oriented around the problems of implosion for the Fat Man bomb.

Los Alamos was the perfect spot for the U.S. government’s top-secret Manhattan Project. Almost overnight, the ranching enclave on a remote plateau in northern New Mexico was transformed into a ...
Established in 1943 as part of the Manhattan Project, the site was home to the Hanford Engineer Works and B Reactor, the first full-scale plutonium production reactor in the world. Plutonium manufactured at the site was used in the first atomic bomb, which was tested in the Trinity nuclear test, and in the Fat Man bomb used in the bombing of ...
Theodore Alvin Hall (October 20, 1925 – November 1, 1999) was an American physicist and an atomic spy for the Soviet Union, who, during his work on United States efforts to develop the first and second atomic bombs during World War II (the Manhattan Project), gave a detailed description of the "Fat Man" plutonium bomb, and of several processes for purifying plutonium, to Soviet intelligence.
Plenty know J. Robert Oppenheimer's name, but do you know the Ames scientists who contributed to the atomic bomb? How work at Iowa State made Oppenheimer's Manhattan Project and the atomic bomb ...
