APRIL 10, 2025 – The U.S. Space Force – the service charged with securing the Nation’s interests in, from and to space – has published Space Force Doctrine Document 1 – The Space Force, articulating doctrine that defines the service’s foundational tenets moving forward.
Chief of Space Operations Gen. Chance Saltzman urged Guardians to read and understand SFDD-1 during a keynote address March 3 at the Air and Space Forces Association Warfighter Symposium.
“The Space Force will do whatever it takes to achieve Space Superiority,” Saltzman said. “If you take away one request from my remarks, then let it be that you read SFDD-1 as soon as its available … think about what it means to you and your daily activities … and discuss it with your fellow Guardians. This is the first step in a much longer journey.”
SFDD-1 codifies why we fight, who we are, what we do and how we integrate into the joint force.
Describing the criticality of national and military spacepower, our guiding foundations and statutory roles, as well as the service’s mission and theory of competitive endurance, establishes a foundation for why the U.S. Space Force exists as a service. SFDD-1 also codifies our values, officer, enlisted and civilian roles, how the U.S. Space Force functionally organizes and key relationships.
SFDD-1 then describes the employment of spacepower, and its core functions of space control, global mission operations and space access. SFDD-1 also describes key principles of command and control, mission command and battle management.
The doctrine document concludes with how the Space Force presents ready space forces, to include the role of the commander of space force forces, combat formations, readiness and more.
The Space Force’s success or failure hinges entirely on the performance of Guardians, Saltzman wrote in the foreword to the document.
“At every level in any role, it is our responsibility to sharpen our readiness and to prepare for the challenges before us,” Saltzman wrote. “Time and again, Guardians have demonstrated the confidence and skills necessary to overcome any obstacle, and it is Guardians who will ensure the Space Force answers our Nation’s call. Your character, commitment, connection, and courage are why I am confident that the Space Force can fight and win against any adversary.”
