The Manhattan Project began in 1942 and ended in August 1947, with the establishment of the Atomic Energy Commission. A rough estimate is that in this time 15 to 20 atomic bombs had been built, with 5 of those detonated, leaving a stockpile by the time the Manhattan Project ended of 10 to 15 atomic bombs.
The project was codenamed "The Manhattan Project" in the United States under the Truman administration.
The project to build the atomic bomb was given the secret code-name of "The Manhattan Project", however the bombs were not built in Manhattan. Check wikipedia for details on actual locations.

The Manhatten Project was the orginization that developed the atomic bomb.
Manhattan project
the answer is "THE MANHATTAN PROJECT" :D
The atomic bomb was not invented by a project, it was invented by Leo Szilard in 1933.However the Manhattan Project built the first ones in 1945.
The military project to develop the US atomic bomb was the Manhattan Project. It included the first successful fission chain reaction in December, 1942, and culminated in the first atomic test explosion at Alamagordo, NM on July 16, 1945. Two bombs built under the project were dropped on the Japanese cities of Hiroshima and Nagasaki.
The united states researched, built, tested and created the first atomic weapon.
The United States, with assistance from the United Kingdom and Canada, designed and built the bombs under the codename Manhattan Project naming Robert Opperheimmer head of the team. You could see the basic diagrams of the bomb but the specific specifications remain classified.
Leo Szilard, the inventor of the atomic bomb (patent GB630726), did not build it himself. He wrote a letter that he had Albert Einstein sign and send to president FDR warning of the potential of atomic bombs and that the Nazis were probably working on them already. If the Nazis got atomic bombs first the Allied cause was lost. FDR authorized funds for a study, the study recommended a full program be begun under direction of the Army. This program became the Manhattan Project, which built the bomb. Leo Szilard was one of hundreds of scientists employed by the Manhattan Project during WW2.
