Groves and Parsons drafted a proposed organization and charter for the AFSWP, which they sent to Eisenhower and Nimitz for approval in July 1947.[18] Groves did not get everything that he asked for; he wanted a status equal to that of a deputy to the Chief of Staff and Chief of Naval Operations, but the most that Eisenhower and Nimitz would allow was a status equal to that of the heads of a technical service, although Groves still reported directly to them. They also characterized his role as a staff post rather than a command, although Groves was already exercising the functions of a commander at Sandia. After the National Security Act of 1947 created an independent Air Force, Groves reported to the Chief of Staff of the Air Force as well, and was given a second deputy chief from the Air Force, Major General Roscoe C. Wilson, who had worked on the Silverplate project during the war.[19]
