CHELMSFORD, Mass.--(BUSINESS WIRE)--Nov. 7, 2001

New ASPARCS Mobile Systems Will Improve Deployment Mobility and

Provide All-Weather Landing Capabilities

Mercury Computer Systems, Inc. (NASDAQ: MRCY), a leading supplier of real-time digital signal and image processing systems, today announced that it has entered into an agreement with Lockheed Martin Corporation's Naval Electronics & Surveillance Systems (NE&SS) division in Syracuse, New York. Mercury will supply its commercial off-the-shelf (COTS) RACE++(TM) products for use in the U.S. Marine Corps Air Surveillance and Precision Approach Radar Control System (ASPARCS). The ASPARCS program will upgrade the AN/TPS-73 radar now in use and will provide a highly mobile, rapidly deployable air traffic control radar designed to improve security for the safe landing of combat and transport aircraft.

The precision approach radars built for ASPARCS will also be available to the United States Air Force for use in its Mobile Air Traffic Control System (MACS).

Mercury systems will be used in the Air Surveillance Radar (ASR) of ASPARCS. The ASPARCS system sits in the back of a Humvee (High-Mobility Multi-Wheeled Vehicle, or HMMWV) and its antenna fits in an accompanying trailer. The system's hardware consists of three primary elements. One is the surveillance radar, which guides planes from a distance of about 60 miles from the field. Another element is the precision-approach radar, which is used during final approach to allow controllers to bring aircraft into the field safely in all weather conditions. The control center, with four controllers, is located in a tent connected to the back of the Humvee.

"Mercury's products are often used in surveillance platforms where there are significant space constraints," said Vince Mancuso, general manager of the Government Electronics Group at Mercury Computer Systems. "The implementation of radars in Humvees is a logical -- but challenging -- next step in the evolution of COTS technology in defense applications. By working with Lockheed Martin NE&SS to implement radar upgrades in demanding platform environments, we continue to validate the DoD's direction and reliance on COTS. Mercury's COTS embedded solutions reduce the power and weight requirements, which results in more affordable enhancements to existing applications."
