The Manhattan Project was the project to develop the first nuclear  weapon (atomic bomb) during World War II by the United States, the  United Kingdom, and Canada.
The history of the Manhattan Project remained classified for many years. In fact, it was so secret that Harry S. Truman, although vice president of the United States, was not made aware of its existence until after the death of Roosevelt in 1945.he program that developed the atomic bomb for the United States during World War II was the largest secret project ever undertaken by the U.S. government. The project was originally named Development of Substitute Materials, but there was concern that the name was too suggestive of its real purpose.
