Manhattan Project Information

The Manhattan Project was a project dedicated to creating an atomic bomb in America during World War II (Bellis, History of the Atomic Bomb & The Manhattan Project.) It was called The Manhattan Project because the project needed a code name so that enemies would not know that America was creating an atomic bomb (Broad, Why They Called It the Manhattan Project.) There are many reasons why it was called the Manhattan Project. The main reason is that there was a uranium warehouse in Manhattan and uranium is the main element used to create the atomic bomb (Broad, Why They Called It the Manhattan Project.) Other reasons that the project was called this was Manhattan was where the project’s first headquarters was located and laboratories that split the atom were also located here (Broad, Why They Called It the Manhattan Project.) There were 10 sites that were purchased to do work for the atomic bomb on (Broad, Why They Called It the Manhattan Project.) The atomic bomb was made on the site in Oak Ridge, Tennessee at the Columbia University (Bellis, History of the Atomic Bomb & The Manhattan Project.) The main issue that was found in making the atomic bomb was getting “enriched” uranium (Bellis, History of the Atomic Bomb & The Manhattan Project.) Uranium at the time was hard to come by but it was even harder to find the right type of Uranium to be used in the bomb (Bellis, History of the Atomic Bomb & The Manhattan Project.) The Uranium isotope that was needed in this project was Uranium-235 (Bellis, History of the Atomic Bomb & The Manhattan Project.) Another issue that was found in the project was that the chemical makeup of U-235 is very similar to the chemical makeup of U-238 (Bellis, History of the Atomic Bomb & The Manhattan Project.) What this means is that the scientists could easily mistake U-238 for U-235 and the bomb would not work because only U-235 could be used. After spending $2 million on this project the project was finally finished on July 16th, 1945 after six years of working to make the bomb (Bellis, History of the Atomic Bomb & The Manhattan Project.)
