BURLINGTON, CANADA – March 21, 2005 – L-3 Communications WESCAM (L-3 WESCAM), a wholly owned subsidiary of L-3 Communications, announced today that is has been awarded a contract from the Naval Air Systems Command (NAVAIR) that could see over 70 multi-sensor MX-15 electro-optical and infrared (EO/IR) systems installed on U.S. Navy P-3C maritime patrol aircraft in the next 5 years. This competitive award augments the original contract received by L-3 WESCAM in 2004 for six MX-15 systems.

Uniquely suited for Intelligence, Surveillance and Reconnaissance (ISR) applications over land and sea, the MX-15 is a key element of the Navy’s Critical Obsolescence Program (COP). With its requirements for an advanced, highly reliable and proven EO/IR sensor system to replace current Infra-Red Detection Systems (IRDS), NAVAIR began system upgrades in 2004 after taking delivery of its first six MX-15s.

“Currently, the U.S. P-3 Anti-surface Warfare Improvement Program (AIP) community successfully operates over 60 of our larger, longer-range MX-20 Advanced Imaging Multi-spectral Sensor (AIMS) turrets,” said John Dehne, president of L-3 WESCAM. “We are pleased with the U.S. Navy’s confidence in the MX Family of turrets and in the selection of the MX-15 for its non-AIP fleet.”

L-3 WESCAM is the only company that supplies a true family of sensor systems, spanning such a broad range of size, weight and performance. The MX Family of turrets maximizes the use of common components and interior electronics, simplifying interchangeability with efficiencies in support, technology growth and reduced life cycle cost.

Organizations such as the U.S. Coast Guard and the U.S. Bureau of Customs & Border Protection have mixed fleets of aircraft that are already leveraging the benefits of the MX Family.

L-3 WESCAM is a world leader in the design and manufacture of stabilized, multi-spectral airborne imaging systems. To learn more about L-3 WESCAM, please visit the company’s web site at www.wescam.com.
