United States Space Force (USSF) doctrine guides the proper use of military spacepower in support of the Service’s cornerstone responsibilities. It establishes a common frame of reference on the best way to plan and employ Space Force forces as part of a broader joint force. This doctrine provides official advice to execute and leverage spacepower using its core competencies. It is not directive—rather, it provides Guardians an informed starting point for decision making and strategy development.
Space Doctrine Publication 3-100, Space Domain Awareness (SDA), aligns with current Space Force doctrine and the Chief of Space Operations’ Planning Guidance. It articulates best practices and lessons learned for achieving SDA, using existing capabilities, to ensure the ability to operate safely while protecting and defending our freedom to operate in space.
Strength and security in space provides national leaders with independent options and enables freedom of action in space and other warfighting domains while contributing to international security and stability. Effective SDA is foundational for space forces to conduct prompt and sustained operations that fulfill the cornerstone responsibilities of the Space Force: preserving freedom of action in the space domain, enabling joint lethality and effectiveness, and providing independent options capable of achieving national objectives. Space Force commanders and their staffs rely on timely and actionable SDA to satisfy these responsibilities.
