THE DEFINITIVE COLLECTION OF U.S. SPACE FORCE KEYSTONE AND OPERATIONAL DOCTRINE Format: 8.5 x 11 inches, Full-Color, Paperback All publications are current as of 14 Dec 25 . Space is no longer a benign environment; it is a complex, contested warfighting domain essential to national security and global stability. This compilation gathers the eight foundational Space Doctrine Publications (SDP) that form the intellectual framework of the United States Space Force (USSF). From the high-level principles of spacepower to the granular mechanics of targeting and logistics, this volume provides the official advice and best practices for Guardians to preserve freedom of action, enable joint lethality, and provide independent options for the Nation. Presented in a large 8.5" x 11" format with full-color graphics, this book serves as an essential reference for Space Force personnel, joint warfighters, policy makers, and defense professionals seeking to understand the tactical and operational conduct of the 21st-century space service. INCLUDED IN THIS VOLUME: SDP 2-0, Intelligence (19 Jul 23): Defines the critical role of intelligence in achieving decision advantage.
