The United States (U.S.) has deepening dependence on space systems for economic prosperity, civil government administration, priority science and exploration programs, and national security while at the same time there is dramatic growth in competitive space capabilities and demonstrated threats to space systems globally. Despite this, the U.S. has not invested sufficient resources to meet National policy direction for capabilities to insure freedom of action in space, especially space situational awareness capabilities—the cornerstone of deterrence from space attacks. A principle reason for this shortfall is the historical absence of an organization accountable for securing the space domain like those of land, sea, and air. Using the analogy of the Army Air Corps, the author recommends creation of an autonomous Space Corps realized out of existing organizations within the USAF. The AF Space Corps would manage a separate space budget and all space professionals in organizing, training, and equipping national security space capabilities including those necessary to secure the space domain for peaceful use.
