The mission of the United States Air Force is to deliver sovereign options for the defense of the United States of America and its global interests - to fly and fight in Air, Space, and Cyberspace. Our space forces perform functions that are critical for the joint force- intelligence, surveillance and reconnaissance; command and control; positioning, navigation, and timing; weather services; counterspace; communications; and spacelift. As our reliance on space increases, so too, must our ability to integrate space capabilities throughout joint operations. To retain the US military's asymmetric advantage based on space superiority, our Air Force must fully exploit and defend the space domain.
