- The Manhattan Project was a massive US government effort during WWII to develop atomic bombs, involving unprecedented industrial and scientific challenges.
- It required the construction of enormous facilities like Oak Ridge and Hanford to produce fissile materials (Uranium-235 and Plutonium) on an industrial scale.
- Multiple methods for uranium enrichment (electromagnetic, gaseous diffusion, thermal diffusion) and plutonium production were pursued simultaneously due to uncertainty and urgency.
- Los Alamos was the primary site for bomb design, where scientists worked on both gun-type and implosion mechanisms, with the latter becoming necessary for plutonium due to spontaneous fission issues.
- The project overcame numerous technical challenges, including xenon poisoning in reactors, implosion symmetry, and remote handling of radioactive materials.
- The first atomic bombs, 'Little Boy' (uranium gun-type) and 'Fat Man' (plutonium implosion-type), were successfully tested and deployed in 1945.
- The Manhattan Project's success was due to parallel development paths, massive funding, and the collaboration of top scientists and engineers.
