first space organization, the Western Development Division, under the leadership of General Bernard Schriever. The Western Development Division and its successor organization, the Air Force Ballistic Missile Division, were instrumental in developing the first United States military launch vehicles and spacecraft, competing predominantly with the Army Ballistic Missile Agency under the leadership of General John Bruce Medaris and former German scientist Wernher von Braun. The launch of Sputnik 1 spurred a massive reorganization of military space, and the 1958 establishment of the Advanced Research Projects Agency was a short-lived effort to centralized management of military space, with some fearing it would become a military service for space, with authorities being returned to the services in 1959. The establishment of NASA in 1958, however, eliminated the Army Ballistic Missile Agency, resulting in the Air Force Ballistic Missile Division serving as the primary military space organization. In 1961, the Air Force was designated as the Department of Defense's executive agent for space and Air Research and Development Command was reorganized into Air Force Systems Command, with the Air Force Ballistic Missile Division being replaced by the Space Systems Division - the first Air Force division solely focused on space. In the 1960s, military space activities began to be operationalized, with Aerospace Defense Command taking control of missile warning and space surveillance on behalf of NORAD, Strategic Air Command assuming the weather reconnaissance mission, and Air Force Systems Command operating the first generations of communications satellites on behalf of the Defense Communications Agency. In 1967, the Space Systems Division and Ballistic Missiles Division were merged to form the Space and Missile Systems Organization, which began to develop the next generation of satellite communications, space-based missile warning, space launch vehicles and infrastructure, and the predecessor to the Global Positioning System. Space forces saw their first employment in the Vietnam War, providing weather and communications support to ground and air forces. The disjointed nature of military space forces across three military commands resulted in a reevaluation of space force organization within the Air Force. In 1979, the Space and Missile Systems Organization was split, forming the Space Division, and in 1980, Aerospace Defense Command was inactivated and its space forces transferred to Strategic Air Command. Resulting from internal and external pressures, including an effort by a congressman to rename the Air Force into the Aerospace Force and the possibility that President Reagan would direct the
