The Missile Defense Agency and Navy continued testing the versatility of the SM-6 missile with a salvo of two missiles fired at a ballistic missile target in the “terminal” or final phase of flight early this morning off Hawaii. The Pearl Harbor destroyer USS John Paul Jones fired the defensive missiles after a target missile was launched from the Pacific Missile Range Facility on Kauai just after midnight. The target missile represented a medium-range ballistic missile — something the U.S. military is increasingly concerned about.
