Space Capstone Publication
Space Capstone Publication, Spacepower
The inaugural Space Capstone Publication, Spacepower (SCP) 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.

This doctrine publication is official advice and commanders should follow it except when, in their judgment, circumstances dictate otherwise. By its nature, doctrine is not directive, and instead provides the Space Force an informed starting point for decision-making and strategy development. Doctrine reflects fundamental principles and best practices based on extant capabilities. It incorporates changes derived from lessons learned during operations, training, wargames, exercises, and, when appropriate, validated concepts.
