TUCSON, Ariz., Oct. 31, 2013 /PRNewswire/ -- Raytheon Company (NYSE: RTN) and
its Japanese partner, Mitsubishi Heavy Industries, have completed the Standard
Missile-3 (SM-3) Block IIA guided missile Critical Design Review (CDR). The
CDR verified that the missile's design will meet the stringent, specific
operational performance requirements necessary to defeat the projected
threats. The SM-3 Block IIA will defeat incoming ballistic missile threats by
colliding with them in space, and the program is on track to begin flight
testing in 2015.

In a precedent-setting co-development effort between allies, the U.S. and
Japan have determined an equitable workshare agreement that defines by missile
section the development responsibility between each country.

"This milestone is critical because it moves the SM-3 Block IIA program from
design to build," said Dr. Taylor W. Lawrence, president of Raytheon Missile
Systems. "Once deployed, SM-3 Block IIA will provide the U.S. and Japan
capability to defend larger geographic areas from longer-range ballistic
missile threats."

The SM-3 Block IIA program plan included building hardware early, supporting
completion of critical subsystem testing prior to CDR. This "hardware rich"
approach coupled with the design commonality with previous versions of SM-3
reduces integration risk.

"We worked closely with the Missile Defense Agency to ensure our design plan
was well thought out, allowing us to build and test along the way. This method
will go a long way toward lowering our risk during future flight testing,"
said Tim Lardy, Raytheon Missile Systems' SM-3 Block IIA program director.

Over the course of 18 months, the Raytheon-Mitsubishi Heavy Industries team,
along with various subcontractors, successfully completed more than 80
rigorous subsystem reviews leading up to the final "system" CDR.

About the Standard Missile-3
SM-3s destroy incoming ballistic missile threats in space using nothing more
than sheer impact of collision, which is equivalent to a 10-ton truck
traveling at 600 mph. The SM-3 Block IIA is the third evolution of the SM-3
family of guided missiles and builds on the successful legacy of the first two
variants: SM-3 Blocks IA and IB.

  oSM-3 Block IIA will have two distinct new features:

       o21-inch 2nd and 3rd stage rocket motors;
       oA larger, more capable kinetic warhead.

  oSM-3 Block IIA will be deployed at sea and on land.
  oMore than 155 SM-3s have been delivered to U.S. and Japanese navies.
