Raytheon Standard Missile-3 Block IB Completes Major Development Milestone

TUCSON, Ariz., July 13, 2009 /PRNewswire/ -- The Raytheon Company (NYSE: RTN) Standard Missile-3 Block IB program completed its critical design review. Completing the CDR clears the way for a 2010 flight test and eventual deployment to the Missile Defense Agency's Aegis Ballistic Missile Defense systems.

SM-3 Block IB offers significant improvements compared with the currently deployed SM-3 Block IA. The upgraded missile features a two-color infrared seeker with advanced signal processing, which enables longer-range target acquisition and enhanced threat discrimination. A new throttleable divert and attitude control system improves SM-3 Block IB flexibility in flight control and reduces cost.

"SM-3 Block IB is designed to outpace the evolving ballistic missile threats," said Dr. Taylor W. Lawrence, Raytheon Missile Systems president. "SM-3 Block IA is a mature, proven system that is protecting the U.S. and its allies today."

SM-3 is being developed as part of the Missile Defense Agency's sea-based Aegis Ballistic Missile Defense System. The missiles are deployed on U.S. Aegis cruisers and destroyers and Japanese destroyers to defend against short- to intermediate-range ballistic missile threats in the ascent and midcourse phases of flight.
