The Manhattan Project was divided into several secret sub-projects, each with its own specific goals. Some of the most important sub-projects included:
* The Los Alamos Laboratory: This laboratory was responsible for the design and development of the atomic bombs. It was located in New Mexico, and was led by physicist J. Robert Oppenheimer.
* The Oak Ridge National Laboratory: This laboratory was responsible for the production of uranium-235, one of the two fissile materials used in the atomic bombs. It was located in Tennessee, and was led by physicist Clinton P. Anderson.
* The Hanford Site: This site was responsible for the production of plutonium-239, the other fissile material used in the atomic bombs. It was located in Washington state, and was led by physicist Hanford D. Smith.
The Manhattan Project was a massive undertaking, involving the work of thousands of scientists, engineers, and technicians. It was also one of the most expensive projects in history, costing over $2 billion.
The Manhattan Project was successful in producing the world's first atomic bombs. These bombs were used to end World War II, and they ushered in the nuclear age.
