CHELMSFORD, MA -- Mercury Computer Systems, Inc. (NASDAQ: MRCY) announced today it has received the first production orders from BAE SYSTEMS for RACE++(TM) Series systems to be used in the SAMPSON advanced multifunction radar. SAMPSON is a key component of the Principal Anti-Air Missile Systems (PAAMS) for the Royal Navy's Type 45 Destroyer. The current program contract value is approximately $8 million. Mercury previously announced in May 2000 that its systems were chosen for the development of the SAMPSON radar application software. In this new order, for seven RACE++ Series PowerStream(TM) 510 systems, one system will be used for environmental testing and qualification, while the remaining systems will be used for the first SAMPSON radar systems. "BAE SYSTEMS' SAMPSON radar design is among the most advanced in the world and it requires a significantly increased amount of signal processing power," said Andy Pine, managing director of Mercury Computer Systems, Ltd. "We have had a long-standing relationship with BAE SYSTEMS and our fully integrated signal processing systems will provide the Royal Navy with the computing power and reliability it requires. These systems are designed and manufactured for deployment in mission-critical applications." "We selected the PowerStream as a fully integrated, deployable system for the Royal Navy's Type 45 Destroyers," said Giles Whitefield, BAE SYSTEMS Project Manager. "Mercury's multicomputers can operate at the extreme shock and vibration levels that this type of ship is designed to withstand. In addition, Mercury's systems offer reliable real-time performance and rapid deployment capabilities, which are also invaluable in this environment." PAAMS including the SAMPSON radar will be deployed on the Royal Navy's next-generation Type 45 Destroyer. SAMPSON is one of the most progressive radar systems in the world, using digital adaptive beam forming, making it virtually immune to electronic jamming. Mercury's RACE++ systems will provide the high-performance, real-time digital signal processing necessary to support the high data rates needed to enable early detection of small targets in a harsh environment.
