Air Force Space Command (AFSPC), sometimes referred to informally as U.S. Space Command[7], is a major command of the United States Air Force, with its headquarters at Peterson Air Force Base, Colorado. AFSPC supports U.S. military operations worldwide through the use of many different types of satellite, launch and cyber operations. Operationally, AFSPC is an Air Force component command subordinate to U.S. Strategic Command (USSTRATCOM), a unified combatant command. It is the primary space force for the U.S. Armed Forces.

More than 38,000 people perform AFSPC missions at 88 locations worldwide and comprises Regular Air Force, Air Force Reserve and Air National Guard military personnel, Department of the Air Force civilians (DAFC), and civilian military contractors. Composition consist of approximately 22,000 military personnel and 9,000 civilian employees, although their missions overlap.

AFSPC gained the cyber operations mission with the stand-up of 24th Air Force under AFSPC in August 2009.

On 1 December 2009, the strategic nuclear intercontinental ballistic missile (ICBM) mission that AFSPC inherited from Air Combat Command (ACC) in 1993, and which ACC had inherited following the inactivation of Strategic Air Command (SAC) in 1992, was transferred to the newly established Air Force Global Strike Command (AFGSC).
