The target missile lifted off about 3:40 p.m. Pacific Standard Time from the Army's Ronald Reagan Test Site at Kwajalein Atoll in the Marshall Islands. About six minutes later, a Ground-Based Interceptor was launched from Vandenberg Air Force Base in California to find, hit and destroy the target.

The MDA said both missiles "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."

The Sea-Based X-band Radar is part of the network of sensors that helps identify and track incoming missile threats, providing information to commanders and the responding interceptor missiles.

Boeing is prime contractor for the GMD program, with industry partners including Raytheon, Orbital Sciences and Northrop Grumman. Lockheed Martin and Raytheon are among the companies here also working on other elements of the U.S. missile defense system.
