The chief of space operations (CSO) is the service chief of the United States Space Force. The CSO is the principal military adviser to the secretary of the Air Force for Space Force operations and, as a member of the Joint Chiefs of Staff, a military adviser to the National Security Council, the secretary of defense, and the president. The CSO is a statutory office held by a Space Force general, who is typically the highest-ranking officer on active duty in the Space Force. The CSO is an administrative position based in the Pentagon, and while they do not have operational command authority over Space Force forces, the chief of space operations does exercise supervision of Space Force units and organizations as the designee of the secretary of the Air Force.
