The process of building the two atomic bombs was long and hard. The Manhattan project employed 120,000 people, and cost almost $2 billion. Although there were 120,000 Americans working on the project only a select group of scientist knew of the atomic bomb development. Vice president Truman never knew about the development of the bombs until he became president. The axis powers did not know what was going on with the development of the atomic bomb; there was a soviet spy in the project. The soviet spy was Klaus Fuchs, and he had become one of the few people who knew of the bombs.
In the summer of 1945 Robert Oppenheimer was prepared to test the first atomic bomb. Which was July 16, 1945 the bomb was tested. The bomb was tested at the Trinity site, and was attached to a tower that was 100 feet high. The scientists were not fully prepared for the power of the atomic bomb. The flash from the explosion could be seen from 200 miles away, and the mushroom cloud was close to 40,000 feet high. The force of the explosion broke windows in surrounding houses within 100 miles of the testing site. The powerful explosion had created a crater a half-mile wide; the heat from the bomb turned the sand into glass.
The Atomic bombs were unlike any bombs that had ever been seen before. The explosion from the test bomb was 100 times stronger than the strongest bomb ever created prior. When the bombs were being developed none of the scientist knew if they would actually work. Even up to the day of the bombings the scientist were unsure if the bombs would explode or just fall to the ground. Although there were test bombs each and every bomb was different, thus making the scientist unsure of the explosions at anytime. To the United States, a dud bomb would be just as bad or worse than no bomb at all. Estimates from many physicists say that the bombs only used 1/10 of the power they were capable of using.
The atomic bombs evolved because of the American military looking for a quick and effective way to end the war Japan was on the verge of giving up. Most of their military was destroyed; they had very few planes and ships left. As well the bombs were created in secret to prove a point. That point being that the American army could do something as large as the atomic bombs with out anyone knowing. Japan’s economy was hurting because Tokyo had been fire bombed; yet they still were refusing to give in. The United States were pulling all of the resources they could and toying with other ideas. Dropping the atomic bombs was one of the last resorts the U.S. army had. There were other ideas looked at, such as having the soviet join in, and invading Japan.
The city of Nagasaki was one of the largest ports in Japan, thus making the city a good target for one of the atomic bombs. The city was also a large player in the economy of Japan because of the many varied industries. Hiroshima was the main target of the atomic attack. There were two targets for the second...
