To support warfighters in the 21st century, Army and joint space operations must adapt to a congested, contested, and competitive international space environment. This monograph examines how the Army is postured to meet current and future space-based support needs to conduct unified land operations. It also provides recommendations regarding how to facilitate the best evolutionary path for future Army space activities to meet the changing environment for unified land operations as well as the diverse challenges of ongoing global operations, technological advances by potential adversaries, increased international competition, and domestic resource constraints. The monograph posits that the Army should retain its current focus on space operations as cross-domain support for terrestrial warfighter operations. It also suggests that the development of such support should include stakeholder and proponency issues with regard to cyberspace operations.
