The United State's Nuclear Weapons Program

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The United States was the first country to develop nuclear weapons, and is the only country to have used them in warfare, with the separate bombings of Hiroshima and Nagasaki in World War II. The work on the ultimate weapon first began under the order of President Franklin Roosevelt in 1939, motivated by the fear that they were engaged in a race with Nazi Germany to develop such a weapon. By investing heavily both in breeding plutonium in early nuclear reactors, and in both the electromagnetic and gaseous diffusion enrichment processes for the production of uranium-235, the United States was able by mid-1945 to develop three operational weapons one of which was used for a test on 16 July 1945 while the other two were dropped on Japanese cities.
