Raytheon's National Missile Defense Prototype Radar Successful In Two Significant Tests

    BEDFORD, Mass., Oct. 12 /PRNewswire/ - The National Missile Defense (NMD)
Ground Based Radar-Prototype (GBR-P) developed by Raytheon Company
(NYSE: RTNA; RTNB) successfully completed two significant, stressing exercises
Sept. 28 against incoming ICBM targets at the South Pacific Kwajalein Missile
    The GBR-P successfully acquired, tracked, and discriminated the target
complexes of two separate operational test missions of Minuteman III missiles
launched toward Kwajalein from Vandenberg AFB, Calif.  The radar test was the
first multi-target, multi-function radar mission using wide band tracking and
    The target complex of the first Minuteman III consisted of two Mk12
Reentry Vehicles (RVs), the target complex (see note to editors for technical
details), a Post Boost Vehicle, third stage booster, and deployment debris.
The target complex, which included objects and spatial separations previously
unavailable on NMD flight tests, provided the opportunity for testing GBR-P's
acquisition, wide band tracking, and discrimination feature functions on a
stressing target scene.  The GBR-P had 35 objects in simultaneous track for
this mission.
    The target complex of the second Minuteman III consisted of three Mk12
RVs, including a NASA payload ejected from one of the RVs, the Post Boost
Vehicle, third stage booster, and deployment debris.  This mission also
demonstrated GBR-P's capability to successfully receive the NMD battle manager
cues and then acquire, track, discriminate, and select the correct RV from the
target complex.
    "The technology used in these important radar missions forms the basis for
the technology Raytheon will incorporate into the X-Band Radar for the future
National Missile Defense system," said William H. Swanson, a Raytheon
executive vice president and president of Electronic Systems.  "Achieving
these successes is another demonstration of Raytheon's world class expertise
in radar technology."
    Work under the NMD contract is being performed at Raytheon facilities in
Bedford, Andover, Sudbury, and Tewksbury, Mass.; Huntsville, Ala.; Kwajalein
Missile Range; Colorado Springs, Colo.; and Dallas, Texas.

    Notes to editors:
    The target complex for the first Minuteman III test included a target
deployment structure, small rigid lightweight replica, radar cross section
matched spheres, reflective and radar transparent balloons, and traffic debris
    BMDO originally announced these tests on Sept. 28. See news release at This Raytheon release
provides considerable added detail regarding performance of the radar.
