Building on this work, Britain prompted the United States to recognise how important this type of research was, helped the U.S. to start the Manhattan Project in 1942, and supplied crucial expertise and materials that contributed to the project's successful completion in time to influence the end of the Second World War.
The formerly secret project was made public by the Smyth Report. In the immediate postwar years, the Manhattan Project assisted weapons testing in Operation Crossroads. It maintained control over American atomic weapons research and production until January 1947, when the Atomic Energy Act of 1946 took effect.
The Manhattan Project began modestly in 1939, but grew to employ more than 130,000 people and cost nearly US$2 billion (about $35.4 billion in 2023 [1] dollars). Over 90% of the cost was for building factories and producing the fissionable materials , with less than 10% for development and production of the weapons.
