Mercury Computer Systems to Support Powerful Technology Upgrade for Airborne Active Electronically Scanned Array Radar

Mercury Computer Systems Inc., (NASDAQ: MRCY, www.mc.com), a trusted provider of commercially developed ISR subsystems, announced it received a multi-year contract from a leading prime contractor to deliver extremely powerful signal processing modules that will be used to field-upgrade advanced active electronically scanned array (AESA) radar systems. These systems are used on-board military aircraft to broadcast strong radar signals while remaining undetected.

"Mercury’s decade-long relationship with this prime contractor exemplifies our commitment to extending customer success over the entire life of a defense program and our ability to deliver critically important upgrades years after initial deployments,” said Didier Thibaud, senior vice president and general manager of Mercury Computer Systems’ Advanced Computing Solutions business unit. "Mercury has a rich heritage of engaging closely with our customers to thoroughly understand their technical and business challenges and to create the best possible solutions. This in-field, module-level upgrade is a prime example of that caliber of partnership.”

The technology Mercury is providing for the AESA system is significantly more powerful than currently deployed solutions. The signal processing modules are fully software compatible, meaning that upgrades can be made easily and quickly in the field. As Mercury continues to support legacy, deployed solutions with significant technology upgrades, it remains the only company to support this caliber of fully compatible, board-swap upgrades.
