The remaining challenges are to induce European allies to contribute more resources to NATO’s collective missile defense efforts and for the United States to make better use of its proven sea-based defenses by incorporating them into a homeland defense role.

On Sept. 9, the MDA detected, tracked and intercepted two medium-range ballistic-missiles that were flying simultaneously over the Pacific Ocean. Satellites and an AN/TPY-2 radar detected the two launches and then helped a warship with the Aegis Ballistic Missile Defense System track one of the missile’s flight path using its on-board AN/SPY-1 radar. The Aegis system then successfully launched an SM-3 Block IA interceptor missile, whose warhead then hit the target.
