Interest by political and military leaders in the United States in adopting the view that space, like the land, sea, and air, is a warfighting domain is growing.[1] This shift in opinion in the nation’s governing and defense-planning circles about the importance of space to national security has led to the reorganization of the Joint Force (establishment of a Space Force) and command structure (reestablishment of U.S. Space Command) to protect U.S. space assets and mature U.S. spacepower. The Missile Defense Agency and its predecessor organizations have understood the importance of leveraging space to accomplish the ballistic missile defense mission since President Ronald Reagan introduced his Strategic Defense Initiative in 1983. Even before then, Army, Navy, and Air Force missile defenders looked to space for a tactical advantage.[2] Is space important to missile defense? If one is observant of history and understands what steps must be taken to destroy in-flight offensive missiles, potentially armed with weapons of mass destruction, then the answer is, “yes, of course.”
Where is the Urgency?
Over the past three decades, the ballistic missile threat, especially from North Korea and Iran, has continued to grow with the development and deployment of more missile systems, systems with global reach, increased speed and maneuverability, greater accuracy, and improved countermeasures. Hypersonic and cruise missiles, which fly very differently from ballistic missiles, are also a growing concern. Russia and China operate advanced ballistic and cruise missile forces, and they are developing and deploying advanced air- and surface-launched long-range cruise and hypersonic missile capabilities. Importantly, hypersonic missiles are being developed to bypass perceived U.S. missile defense capabilities. Regional hypersonic missiles are capable of holding deployed U.S. forces, allies, and partners at risk, so that hypersonic glide vehicles delivered by ballistic missile boosters will pose new challenges to U.S. regional missile defenses.[3]
