The Atlas program led to the belief that the entire responsibility for deploying new weapons systems – from research, development and testing through procurement and production – should be vested in one command, rather than split between Air Materiel Command (AMC) and ARDC. It was the Soviet Union's launch of Sputnik 1 in October 1957 that greatly influenced HQ USAF and ARDC thinking. The Stever Report, completed in June 1958, which proposed a new Air Force command for weapons acquisition. With this report and a realization of DoD's desire to assign the military space mission to the Air Force, the Air Force won the approval of Secretary of Defense Robert S. McNamara in 1961 for a new major command. In the reorganization and re-designation actions of 1961, Air Materiel Command was re-designated Air Force Logistics Command (AFLC) while Air Research and Development Command, gaining responsibility for weapon system acquisition, was re-designated Air Force Systems Command (AFSC) under General Bernard Schriever.
