L-3 Communications' EER Systems, Inc. Awarded Delivery Order to Provide Upgrades to The U.S. Marine Corps' AV-8B Maintenance Training Devices.

Business and Technology Editors

NEW YORK--(BUSINESS WIRE)--Sept. 10, 2002

L-3 Communications (NYSE:LLL) announced today that EER Systems, Inc., a wholly owned subsidiary of L-3, has been awarded an order by the U.S. Navy to modify existing maintenance training devices for the AV-8B aircraft.

The primary use of the modified training devices will be to teach troubleshooting skills necessary to maintain AV-8B Harrier II Plus systems. The total value of the contract with all options exercised is $8 million.

This order was competitively awarded under Lot I of the Naval Air Training Systems Division's (NAVAIR TSD) FY2000 training systems contract. The scope involves the design and modification of the landing gear systems maintenance training device to the radio detection and ranging (RADAR) configuration. There are options for additional RADAR upgrades and also for the integration of the open systems core avionics requirements (OSCAR) upgrade into the maintenance training devices. The work will be performed at EER's Orlando, Florida facility.

Each training device consists of a cockpit, fuselage, instructor operator station, simulation computer, and input/output subsystem. The upgrades include the modification of both hardware and software to integrate the new RADAR and OSCAR upgrades into the existing training devices. Key features of EER's proposed RADAR approach include maximum use of commercial off-the-shelf (COTS) equipment and reuse of existing software, as well as maximum commonality of design with the existing modified suite of training devices. Key features of EER's proposed OSCAR approach include a design that takes advantage of using the operational flight program as a "drop-in" component and the use of a common COTS design across all training devices. These features will provide the Marines with cost effective, highly reliable, and supportable training devices with reduced life-cycle costs.

"This key award builds on EER's impressive background in supporting the Department of Defense's training and simulation efforts," said Robert Urso, president of L-3's EER Systems, Inc. "We are very pleased to have the opportunity to support the U.S. Marine Corps and the U.S. Navy in this critical area."
