The U.S. Army has successfully completed its first open-air testing of an advanced multi-mode seeker, an upgrade to the Precision Strike Missile system. During a two-day test period June 2-3 at Redstone Arsenal, Alabama, research teams operated the seeker at 50 percent capacity while tracking moving targets. The seeker was designed to allow an upgraded “Spiral One” missile to acquire targets on both land and sea. Joseph Lacdan, Army News Service, reports.
