Guardians, When our Service was established in December 2019, we were charged with forging a servicepurpose-built to secure our Nation’s interests in, from, and to space. We have accomplished so As we grow to meet the demands of a rapidly changing domain, it occasionally becomes neces-sary to take stock of our journey: where we have been, where we are today, and where we aregoing. So, rather than a plan or a strategy, I felt it was important to provide our Guardians witha “vector” for what I consider to be the most essential elements of our work. Make no mistake, I Within this document, you will find insight into the way the Space Force conducts the four ser-vice-level activities of Force Design, Force Development, Force Generation, and Force Employ- Our vector is realized through the Service’s doctrine documents, strategies, and concepts, toinclude theSpace Force Doctrine Document-1,Space Warfighting Framework,CommercialSpace Strategy,International Partnership Strategy, and soon-to-be-publishedObjective Force.Likewise, this document highlightsCompetitive Endurance, our theory of success around which If every Guardian can internalize the concepts contained herein, I am confident that we will ac-celerate our transformation into a warfighting service; a Service that embodies warrior ethos,outpaces our adversaries, and protects our Joint Force and our Nation from space-enabled at- I encourage all Guardians to consider the information compiled here and to discuss it within theirformations. We owe it to ourselves, the Joint Force, and the Nation to finish what we started—our B. Chance Saltzman, Gen, USSFChief of Space Operations OUR FORMATIVE PURPOSE Preserving U.S. freedom of action in an increasingly contested space domain requires a militaryforce specifically organized, trained, and equipped for that purpose.This simple observationmotivated the establishment of our Service. While the development and integration of space ca-pabilities has tremendously enhanced the efficiency and effectiveness of the Joint Force, it has Today, the Joint Force depends on space capabilities to project power and provide protectionfrom space-enabled attack to achieve battlefield objectives. Military services are traditionally or-ganized to contest and control specific domains with military force. To that end, the Space Forcewas established to gain and maintain superiority in the space domain on behalf of the Joint Forceand our Nation. Contesting a physical domain is a complex endeavor—it takes a purpose-built For space in particular, this is a difficult task given the extreme speeds, distances, technicalchallenges, and unique environmental conditions involved. The Space Force, like all services,must therefore recruit the right kind of talent and build the right expertise through career-longdevelopment unapologetically focused on the application of military force in its domain. Thisspecialization allows the Space Force to cultivate the skills, experience, and mindset required to The transformation of the Space Force is not unlike an effort to convert a Merchant Marine for-mation into a warfighting Navy. Taking advantage of a benign environment to efficiently deliverservices is important, but when that environment becomes contested, the protection of those Once achieved, Space Superiority enables domain access and exploitation, ensuring the SpaceForce can continue to deliver the game-changing capabilities that make space so integral to themodern way of war and the Joint Force’s success. While this philosophy is core to our Service,we have never conducted a war in space and therefore lack the clarity that comes from combatexperience. For this reason, the Space Force must remain adaptable, intent on assessing andevolving alongside our domain. While the details may shift, we know the direction in which we OUR THEORY OF SUCCESS To organize our efforts, the Space Force has published a theory of success, which we callCom-petitive Endurance. The logic ofCompetitive Enduranceaggregates assumptions, guiding prin-ciples, and conclusions to describe how the Space Force will gain and maintain space superi- The goal ofCompetitive Enduranceis to ensure our ability to achieve Space Superiority whilealso maintaining the safety, security, and long-term sustainability of the space domain. We will 1.)Avoid Operational Surprise.Space forces must be able to detect and identify any pertur-bations in the operational environment to maintain our strategic advantage. This requires aspace domain awareness enterprise capable of executing surveillance and reconnaissance 2.)Deny First-Mover Advantage.At present, space is an offense-dominant domain, incentiviz-ing unwarned attacks. To negate this, space forces must make first strike in space impracti-cal and self-defeating, discouraging such action from the outset. This requires resilient and 3.)Responsible Counterspace Campaigning.While the first two tenets are necessary to protectspace capabil
