United States Space Force Spacepower

The inaugural Space Capstone Publication, Spacepower is capstone doctrine for the United States Space Force and represents our Service's first articulation of an independent theory of spacepower. This publication answers why spacepower is vital for our Nation, how military spacepower is employed, who military space forces are, and what military space forces value. In short, this capstone document is the foundation of our professional body of knowledge as we forge an independent military Service committed to space operations. Like all doctrine, the SCP remains subject to the policies and strategies that govern its employment. Military spacepower has deterrent and coercive capacities - it provides independent options for National and Joint leadership but achieves its greatest potential when integrated with other forms of military power. As we grow spacepower theory and doctrine, we must do so in a way that fosters greater integration with the Air Force, Army, Navy, Marine Corps, and Coast Guard. It is only by achieving true integration and interdependence that we can hope to unlock spacepower's full potential. Agility, innovation, and boldness have always been the touchstone traits of military space forces. Today, we must harness these traits to pioneer a new Service and a new professional body of knowledge. This capstone doctrine is a point-of-departure toward that goal, not a final adjudication. Given the nascent state of spacepower theory, this publication will inevitably evolve over time as it is applied, evaluated, and refined. Therefore, military space forces are encouraged to read, critique, debate, and improve upon the ideas that follow.
