A collaborative effort between Great Britain, United States, and Canada in an effort to win the nuclear weapons race against Germany, Japan, and Russia, the Manhattan Project was born and was considered a huge success in the field of nuclear science. A team of scientists along with General Leslie Groves and Robert Oppenheimer made the plans under the reign of then president Franklin D. Roosevelt. The Manhattan Project was the perfect combination of science, technology, and industry - bringing about the actual power of nuclear fission reactions. Nearly 2 billion dollars was spent on research and development of the atomic bomb, according to US History. One of the few Las Vegas museums to hold such knowledge and artifacts is the National Atomic Testing Museum. There also lies the little-known facts about the war that no one else has ever really imagined.
