Already the United States is pursuing a number of military systems that could be used to attack targets in space from Earth or targets on Earth from space. To China, current U.S. deployment of a Ground-Based Midcourse Missile Defense system represents an intentional first step toward space weaponization. China experts argue that the interceptors of the system based in Alaska and California could be used to attack satellites.After all, such systems could be easily adapted to target satellites, which are more fragile and more predictable than ballistic missile warheads. If the United States is determined to ensure “space dominance,” it would first want to use such weapons to negate an adversary’s satellites.
