The 9th Space Division (9th SD) is an inactive United States Air Force organization. Its last assignment was with Air Force Space Command, being stationed at Patrick Air Force Base, Florida. It was inactivated on 1 October 1991.
The organization has had several periods of activation over its lifetime. Initially established in April 1949 as the 9th Air Division (Tactical) under Fourteenth Air Force, Continental Air Command at Pope AFB, North Carolina, the command had no units assigned but was to act as a headquarters over tactical units. It was inactivated in August 1950.
It was redesignated and reactivated in October 1954 by Air Defense Command (ADC) and assigned to Western Air Defense Force (WADF) at Geiger Field, Washington, taking over control of air defense units in eastern Washington, Oregon and Idaho from the 25th Air Division (AD), after the 25th AD was realigned over the Washington and Oregon coastal area west of the Cascade Mountains. It participated in the United States Air Force collateral mission of antisubmarine warfare and administered, equipped, and trained for combat. It was inactivated in 1958 when the Spokane Air Defense Sector was established by ADC to take over its responsibilities.
The third incarnation of the organization began in 1961 with its reactivation as the 9th Aerospace Defense Division was associated with the North American Aerospace Defense Command by ADC, assuming responsibility for the Ballistic Missile Early Warning System, the Missile Defense Alarm System, the Space Detection and Tracking System, the NORAD Combat operations Center, the Bomb Alarm System, and the Nuclear Detonation System. It was inactivated in 1968 when its mission was elevated to a Numbered Air Force level, being assumed by the Fourteenth Aerospace Force on 1 July.
The most recent incarnation the 9th Space Division began in 1990 when Air Force Space Command (AFSPACECOM) reactivated the organization to provide an action mechanism to "operationalize" the space launch capabilities of Eastern Space and Missile Center (ESMC) and Western Space and Missile Center (WSMC) units transferred from Air Force Systems Command to AFSPACECOM during 1990–1991. ESMC and WSMC became respectively the 45th Space Wing and 30th Space Wing within two months of the Division's inactivation in 1991.
