TEWKSBURY, Mass., Oct. 25, 2004  /PRNewswire/ -- Raytheon Company will
serve as the lead systems integrator for AN/BYG-1, the next generation combat
system for the U.S. Navy submarine fleet.  As the AN/BYG-1 integrator for the
existing U.S. Navy contract, Raytheon Integrated Defense Systems (IDS) will
backfit both Los Angeles-class and Seawolf-class combat systems.

    This role builds upon Raytheon's success as the developer of the AN/BYG-1
weapons control subsystem.  As lead systems integrator, IDS will integrate the
tactical control, weapons control, and tactical network subsystems, each of
which incorporates a variety of advanced process build software algorithms
developed by a host of industry, government, and academia sources.

    Relying on its extensive experience and expertise to manage the
complexities of the system, the rapid pace of technology insertion, the number
of participants involved, and the multiple software builds, Raytheon will
provide the integration and coordination required to ensure complete end-to-
end functionality.

    "As the mission systems integrator in this role, Raytheon is able to
achieve a long-standing goal of the U.S. Navy for a common combat systems
approach to outfit the entire U.S. submarine fleet with a fully compatible and
interoperable combat systems baseline," said Upinder Dhinsa, IDS' vice
president of Naval Integrated Systems.  "This role strengthens Raytheon's
solutions-based focus on providing superior capabilities to the warfighter."

    Raytheon will work in close partnership with the Naval Undersea Warfare
Center (Newport, R.I.) on the program as well as industry teammates involved
with AN/BYG-1 combat control subsystems, including General Dynamics - Advanced
Information Systems; Progeny; and Lockheed Martin.
