From a political and military standpoint, the United States is heavily reliant on space capabilities and holds a tremendous asymmetric advantage over its adversaries with the dominance of its space forces. However, its advantage is unprotected and potential adversaries pose a menacing threat to the national security of the United States. This threat manifests itself in a variety of ways, including the potential for a deliberate attack on its space systems with anti-satellite (ASAT) capabilities, Global Positioning System (GPS) jammers, directed energy threats, parasitic satellite technologies, and numerous other means. Most recently, China demonstrated the ability to destroy a low Earth orbit satellite with a direct ascent medium-range ballistic missile.
