Mission
Space Command's mission is: ''"To conduct operations in, from, and through space to deter conflict, and if necessary, defeat aggression, deliver space combat power for the Joint/Combined force, and defend U.S. vital interests with allies and partners."''
Organization
United States Space Command has two subordinate components. The Combined Force Space Component Command (CFSCC) is responsible for planning and conducting global space operations, while also providing space effects to the other combatant commands and U.S. allied partners. Joint Task Force–Space Defense (JTF-SD) is responsible for conducting space superiority operations.
On 16 November 2022 Combined Force Space Component Command and Joint Task Force–Space Defense will now report to the
Combined Joint Task Force–Space Operations (CJTF-SO), a three-star subcommand of Space Command (the combatant command).
