Raytheon Achieves Critical Dual Band Radar Testing Milestone

TEWKSBURY, Mass., April 7, 2009 /PRNewswire/ -- Raytheon Company (NYSE: RTN)
and the U.S. Navy successfully completed initial "lightoff" testing of the
Dual Band Radar.

The Dual Band Radar is an integrated active phased-array radar suite composed
of the X-band AN/SPY-3 Multi-Function Radar and the S-band Volume Search
Radar, both of which radiated at high power during lightoff at the Navy's
Engineering Test Center, Wallops Island, Va.

"This is an enormous milestone for Raytheon and the Navy -- demonstrating the
reliability and effectiveness of the most advanced naval surface radar in the
world," said Raytheon Integrated Defense System's Bob Martin, vice president
and deputy of Seapower Capability Systems. "The Dual Band Radar provides
unmatched mission capabilities and functionality, while delivering commonality
and affordability for the fleet."

The system will be installed on the Zumwalt-class destroyer (DDG 1000),
Ford-class aircraft carrier (CVN 78), and other future surface combatants to
provide superior surveillance capabilities and support ship self-defense
across a broad range of missions. The Dual Band Radar leverages proven
technologies to meet mission requirements in deep water and littoral, or near
shore, environments.

The radar supports a wide variety of mission requirements, including ship
self-defense and anti-air warfare; anti-submarine warfare; anti-surface ship
warfare; situational awareness; land attack; naval gunfire support; surface
search; navigation; and air traffic control. The radar's capabilities include
horizon search; volume surveillance; fire control tracking; missile guidance;
and illumination functionality for the Evolved SeaSparrow missile and Standard
missile family.

Following this successful lightoff testing, the radar suite will begin an
extended period of operational performance testing.
