TEWKSBURY, Mass., Jan. 13, 2005  /PRNewswire-FirstCall/ -- Raytheon
Company's Affordable Ground Based Radar (AGBR) passed a critical milestone
during a recent United States Marine Corps test in support of the goal to
field future radar sensors configured in a tactical and highly mobile design
for the Marine Expeditionary Forces worldwide.

    In line with the schedule laid out three years ago, in mid-December 2004
the (AGBR) Science and Technology concept demonstrator successfully performed
air surveillance and tracking of simulated and real airborne targets while
rotating at both 30 and 60 revolutions per minute.  This achievement validates
the concept for a battlefield sensor mounted aboard a HMMWV (High Mobility
Multipurpose Wheeled Vehicle).   Further AGBR testing and evaluation are
underway.

    The Marines envision eventually fielding a multi-purpose radar to perform
air surveillance, air defense, ground weapons locating, and air traffic
control.  Currently those roles are each performed separately by aging legacy
radars designed for one single-purpose, using technology that is decades old.
The USMC has designated this new development program as G/ATOR (Ground / Air
Task Oriented Radar); the award of which is anticipated sometime in 2005
following a full and open industry competition.

    Sponsored by the Office of Naval Research (ONR), the USMC's AGBR contract
was awarded in 2002 to Raytheon and is being executed at the Integrated
Defense System's Surveillance and Sensors Center located in Sudbury, Mass.  To
date, the U.S. Marine Corps Systems Command located at  Quantico Marine Base,
Va. have observed more than 50 percent of the planned AGBR prototype tests
being conducted by Raytheon.  The balance of the planned prototype tests are
scheduled for demonstration in January - February, 2005.

    "The results of these tests will furnish the Marine Corps additional
insights into the path ahead, validate the concept for highly mobile multi-
purpose radars for the future Marine Expeditionary Forces, and in-turn,
support the Marines' milestone decision to move forward with the G/ATOR
program," explained Robert Pool, Raytheon's program manager.  "Raytheon is
looking forward to completion of the remaining AGBR tests and the opportunity
to compete for the follow-on G/ATOR development program."
