The Trinity test of the Manhattan Project on July 16, 1945, was the first nuclear weapon detonation. Oak Ridge, Tennessee, United States During World War II, the Manhattan Project was a research and development effort that resulted in the production of the first nuclear weapons. The project was based at the Los Alamos Laboratory in New Mexico and included scientists and engineers from universities and industry across the United States and Canada.
The Trinity test was conducted within sight of where the first atomic bomb was developed years earlier by the University of Chicago Research Division of the National Bureau of Standards (now known as the NBS). This division was called the Met Lab because of its location next to a streetcar line that had the letters "MET" painted on it. The university received permission from the city to use part of their campus for military purposes and they constructed three large buildings for this purpose. One of these was called Building 10 and it was here that the Trinity test was conducted.
The building is now a museum that opens to the public who can see the laboratory where the world's first nuclear weapons were created.
These bombs were very different from anything that had gone before them and they caused problems for scientists working on both sides of the war. American scientists wanted more time to study the effects of these new weapons while German scientists wanted evidence of their effectiveness immediately. In either case, both countries needed places where they could test their bombs.
Trinity was the code name for the first nuclear weapon detonation. It was carried out by the United States Army as part of the Manhattan Project at 5:29 a.m. on July 16, 1945. ... The Holy Trinity (nuclear test)

It was headed by the US, with help from the UK (who launched the initial Tube Alloys project) and Canada. The project was based at the Los Alamos Laboratory in New Mexico under the direction of General Leslie R. Groves.
The project's goal was to develop an atomic bomb as part of the broader effort to develop effective atomic weapons. The first atomic bomb was tested at White Sands Missile Range near Las Cruces, New Mexico, on July 16, 1945. The bombing of Hiroshima and Nagasaki ended the war and brought about the end of the project that produced it.
Los Alamos was chosen as the site for the project because of its isolation: neither the Soviet Union nor China had an air force capable of reaching there before the end of the war. Additionally, the laboratory was home to many scientists who had been hired away from universities and national laboratories across the United States. Finally, the government believed that a town this small could keep something like this secret. Located in central New Mexico, less than 100 miles from Santa Fe, Los Alamos is a community of about 1,000 people. It is surrounded by protected federal land that includes the Los Alamos National Laboratory, which is responsible for research and development work not related to weapons production.
The Manhattan Effort was a covert government project that ran from 1942 to 1946 with the goal of developing a nuclear weapon. It was successful on July 16, 1945, at the Trinity Test in New Mexico, and it went on to generate the two atomic bombs that were used to destroy the Japanese cities of Hiroshima and Nagasaki during WWII. The project was managed by the University of Chicago Laboratory for Nuclear Studies and funded by the United States government. The name "Manhattan Project" is taken from the Manhattan District in which the laboratory was located.
During World War II, the United States government sought to develop an atomic bomb as part as its overall effort toward victory. The first atomic bomb was tested by the United States in 1945; the second was used against Japan in August of that year. The development of the atomic bomb was a team effort that brought together scientists from different backgrounds who were focused on achieving a single goal. The project was supervised by the Army's Research Division (later called the Defense Department's Office of Scientific Intelligence) and the Navy's Bureau of Ordnance. It received support from other departments including the State Department and the Interior Department. Finally, it was overseen by the Special Committee on Atomic Energy, which was established by Congress in 1947 to provide oversight of nuclear energy programs in the United States.
The Manhattan Project employed about 70,000 people during its peak years in 1944-1945.
