Only three atomic bombs have been dropped in history. Little boy, was dropped on the Japanese city of Hiroshima on August 6, 1945. Fat man was dropped on Japan's capital, Nagasaki on August 9, 1945. And finally, Trinity was the code name for a test bomb which was a replica of Fat man. It was dropped on July 16, 1945 in New Mexico. A fourth bomb, named thin man, was proposed and scientists worked on it until it was aborted. These bombs were all used for war purposes in World War two. The code name for the making of these bombs was the Manhattan Project. It started formally in 1942. The US led it but was supported by the United Kingdom and Canada. US president Franklin Roosevelt approved of it in late 1941. It was created for fear Germany was making Atomic Bombs. It employed almost 130,000 people including brilliant scientists such as Albert Einstein. There were over 30 sites in the US, UK, and Canada where research and development took place. It costed 2 billion US dollars, now the equivalent of 26 billion in 2014. The Manhattan Project was under the direction of Major General Leslie Groves of the US Army Corps of Engineers from 1942 to 1946. There were two types of bombs created. A gun type fission weapon(little boy) and an implosion type weapon(fat man). There was no warning of the first atomic bomb for Hiroshima. There was however a warning for Nagasaki. Leaflets were dropped all over the cities of Japan warning of a second atomic bomb, just as deadly as the first. Kokura
