Missile defense test scheduled Published Jan. 31, 2010 By 050110 VANDENBERG AIR FORCE BASE, Calif. -- The Missile Defense Agency conducted a flight test today of the Ground-Based Midcourse Defense System. A target missile was successfully launched at approximately 3:40 p.m. PST from the U.S. Army's Reagan Test Site at Kwajalein Atoll in the Republic of the Marshall Islands. Approximately six minutes later, a Ground-Based Interceptor was successfully launched here. Both the target missile and Ground-Based Interceptor performed nominally after launch. However, the Sea-Based X-band radar did not perform as expected. Program officials will conduct an extensive investigation to determine the cause of the failure to intercept.
