CHELMSFORD, Mass.--(BUSINESS WIRE)--Sept. 23, 2002

Mercury Computer Systems, Inc. (NASDAQ: MRCY), announced today that its French subsidiary, Mercury Computer Systems, S.A.R.L., has received an order for its RACE (R) Series multicomputers from ONERA, the French Aeronautics and Space Research Agency, for a performance upgrade of the Nostradamus early warning over-the-horizon radar. The order for Mercury's real-time systems is valued at approximately $446,000, to be delivered in the first calendar quarter of 2003.

The Nostradamus radar, designed and developed by ONERA, operates in the decametric wavelengths and uses the reflection of high-frequency waves off the ionosphere in a mirror-effect technique for a range beyond the horizon (up to two thousand kilometers) unlike conventional radars that are limited by the earth's curvature. ONERA, a financially independent public, scientific and technical establishment, reports to the French Ministry of Defense.
