Missile defense test delayed Published Dec. 14, 2010 VANDENBERG AIR FORCE BASE, Calif. (AFNS) -- The Missile Defense Agency ground-based interceptor flight test, scheduled for Dec. 14, has been delayed due to poor weather conditions downrange. The flight test has been rescheduled for Dec. 15, with a launch window from 8 a.m. to noon, E.T. The ground-based interceptor test will defend against an intermediate-range ballistic missile target launched from Kwajalein Atoll, Marshall Islands. The operationally-configured interceptor is designed to intercept and destroy a ballistic missile warhead as part of the Ground-based Midcourse Defense element of the integrated Ballistic Missile Defense System. This will be the fourth launch of an operationally configured, ground-based interceptor from here. (Courtesy of 30th Space Wing Public Affairs)
