Business Editors

NEW YORK--(BUSINESS WIRE)--July 25, 2000

L-3 Communications (NYSE:LLL) announced today that with the successful launch of PanAmSat Corporation's Galaxy XI communications satellite, its Storm Control Systems division (L-3 Storm) has again met the challenge of providing a software solution able to perform all aspects of spacecraft integration, factory testing, launch and on-station operations.

Galaxy XI, one of the world's largest communications satellites, marks the debut of Hughes Space and Communications' (HSC) new fleet of 702 satellites. HSC utilized L-3 Storm's Integrated Satellite Interface System (ISIS) for every phase of Galaxy XI deployment. HSC contracted with Storm to create a common satellite software system with the goal of reducing the cost and turnaround time for delivering its 702 spacecraft. Using L-3 Storm's modular architecture and database-driven system, customers are able to eliminate the need to rewrite large portions of ground system software for each new spacecraft and thereby dramatically reduce the recurring costs associated with each spacecraft delivery.

L-3 Storm president Chris Bourassa commented, "L-3 Storm congratulates Hughes and the entire 702 team on passing this crucial milestone. Our work with HSC has allowed us to introduce new additions to our proven family of command and control products, including HTML test-data reporting, automatic dwell and memory dump decommutation, and powerful historical data archiving and viewing capabilities. These advanced tools will ensure our ability to provide superior support for new satellite communication projects to be launched in the coming years."
