Mercury's RACE++ Systems Provide Computing Power for Leading Science and Technology Organization in Europe Mercury Computer Systems, Inc. (NASDAQ: MRCY), a leading provider of embedded real-time digital signal and image processing computer systems, announced today it has shipped high-performance RACE++(tm) systems to the Defence Evaluation and Research Agency (DERA) in the United Kingdom. DERA will use Mercury's multicomputer systems, which incorporate PowerPC(tm) "G4" processors, to perform advanced research for airborne electronic warfare. "DERA is at the leading edge of the research and development chain that brings new products to the aviation industry," said Andy Pine, managing director, Mercury Computer Systems, Ltd. "Being selected by DERA is a significant development in the continued growth of Mercury in the United Kingdom and Europe, where our operations have grown significantly in the last few years." DERA is the largest physics-based research and evaluation organization in Western Europe. For the past five years, Mercury's powerful multicomputer systems have played an important role in DERA's ability to research and develop cutting-edge solutions for the U.K. government's departments involved in civil and military aviation. The new RACE++ systems will enable DERA to step up its research efforts. Based in the U.K. with operations in over 30 sites, DERA has an annual turnover exceeding $1 billion. Working with public sector organizations and private industry, DERA has established a reputation for technical excellence. DERA is the principle supplier of technical advice to the U.K. Ministry of Defence and has supported the U.K. procurement programmes for Eurofighter, Replacement Maritime Patrol Aircraft (RMPA), U.K. Attack Helicopter and Merlin helicopter.
