"Only about six men in the U. S. Army are permitted to know what is going on, including Secretary of War Stimson!" - Arthur Compton; Met Lab; June 1942
The decision to proceed with production planning led directly to the involvement of the Army, specifically the Corps of Engineers. Roosevelt had approved Army involvement on October 9, 1941, and Bush had arranged for Army participation at the S-1 meeting in March of 1942. The need for secrecy suggested placing the S-1 program within one of the armed forces, and the construction experience of the Corps of Engineers made it the logical choice to build the production facilities envisioned in the Conant report of May 23.
By orchestrating some delicate negotiations between the Office of Scientific Research and Development (OSRD) and the Army, Bush was able to transfer the responsibility for process development, materials procurement, engineering design, and site selection to the Corps of Engineers and to earmark approximately sixty percent of the proposed 1943 budget, or $54 million, for these functions. An Army officer would be in overall command of the entire project. This new arrangement left S-1, with a budget of approximately $30 million, in charge of only university research and pilot plant studies. Additional reorganization created a new S-1 Executive Committee, composed of James Conant, Lyman Briggs, Arthur Compton, Ernest Lawrence, Edgar Murphree, and Harold Urey. This group would oversee all OSRD work and keep abreast of technical developments that might influence engineering considerations or plant design. With this reorganization in place, the nature of the American atomic bomb effort changed from one dominated by research scientists to one in which scientists played a supporting role in the construction enterprise run by the United States Army Corps of Engineers.

Atomic Story of the Week
The Eastman Kodak guy that was interviewing me gave me the General Groves treatment! I asked him, “Where will I be working? Will I work for you guys in Rochester?”
“No, won’t be working in Rochester.”
“Well, where will I be working?”
“Well, I can’t tell you.”
“Well, what kind of work will I be doing?”
“Well, it’s going to be war work.”
But I said, “what kind of chemistry will it be? Organic, inorganic, physical?”
