Northrop Grumman to Provide Improved Air-Traffic Control Voice-Communications Systems for United Kingdom

PETERBOROUGH, England, July 15, 2005 (PRIMEZONE) -- Northrop Grumman Corporation (NYSE:NOC) has won a contract with the United Kingdom's National Air Traffic Services to modernize their nationwide air-to-ground communications system that connects pilots with air-traffic controllers.

The contract, worth approximately $35 million, will help modernize the voice-communications systems and VHF/UHF radio facilities within the National Air Traffic Services communications infrastructure over the next seven years.

National Air Traffic Services provides air-traffic control services to aircraft flying in United Kingdom airspace and over the eastern part of the North Atlantic. The air-traffic control is provided from four United Kingdom-based centers in Swanwick, West Drayton, Prestwick and Manchester.

This year National Air Traffic Services will handle more than two million flights carrying over 180 million passengers. Northrop Grumman's work will facilitate the National Air Traffic Services' objective to handle all en route traffic from just two centers -- Swanwick and Prestwick.

Northrop Grumman's solution is based on a voice communication control system (GAREX 220) and a multimode digital radio (PAE T6) developed by its Park Air Systems, Ltd., subsidiary.

The GAREX 220 control system -- a fully digital switching system -- provides air-traffic controllers with instant access to all available communications including media, radio, telephone and intercom. The PAE T6 digital radio provides surface-to-air analog and digital communication in the VHF and UHF bands.

"Together, these proven, reliable air-traffic control products will provide a digital end-to-end system delivering high-quality voice communications between the control centers and aircraft," said Charles Houseago, managing director of Park Air Systems.

Park Air Systems Ltd., based in Peterborough with a major facility in Oslo, Norway, supplies communication, navigation and surveillance systems for air-space operations worldwide. It is a component of Northrop Grumman's Baltimore-based Electronic Systems sector, a world leader in the design, development and manufacture of defense and commercial electronics and systems including airborne radar, electronic countermeasures, space sensors, navigation systems, communications systems, precision weapons, airspace management systems, marine and naval systems, government systems and logistics services.
