USSPACECOM has two subordinate commands: Combined Force Space Component Command (CFSCC) and Joint Task Force Space Defense (JTF-SD).
CFSCC plans, integrates, conducts, and assesses global space operations in order to deliver combat relevant space capabilities to Combatant Commanders, Coalition partners, the Joint Force, and the Nation.
JTF-SD conducts, in unified action with mission partners, space superiority operations to deter aggression, defend U.S. and Allied interests, and defeat adversaries throughout the continuum of conflict.
