ELKRIDGE, Md., Nov. 16, 2009 -- Northrop Grumman Corporation (NYSE:NOC) has announced the successful demonstration of the company's Next Generation Voice Over Internet Protocol (VoIP) Voice Switch to officials of the U.S. Federal Aviation Administration (FAA) in preparation for the upcoming National Airspace System (NAS) Voice Switch (NVS) program competition.

The voice switches support communications between air traffic controllers and pilots, in addition to communications between multiple air traffic controllers. Compared with the FAA's legacy communications switches, the new voice switch product being offered by the company's Denro Systems business unit is designed to provide increased performance, reliability and flexibility.

The demonstration was the second phase of Northrop Grumman's response to a Request for Information (RFI) issued by the FAA for the NVS program.

"The new voice switch product met and, in many cases, exceeded the FAA's National Airspace System requirements," said John Jadik, vice president, Communications, Intelligence and Networking Solutions for Northrop Grumman's Land Forces Division. "The demonstration marked the successful culmination of Northrop Grumman's multi-year investments and development efforts to design a new generation of communications systems targeted specifically for the FAA's NVS program."

Northrop Grumman's Denro Systems business unit, previously located in Gaithersburg, Md., and now based at the company's Troy Hill facility in Elkridge, Md., has been a leading provider of voice and data switches and related logistics support services to the FAA and U.S. Department of Defense over the past 30 years, with more than 2,000 systems delivered both domestically and internationally.

Northrop Grumman Corporation is a leading global security company whose 120,000 employees provide innovative systems, products, and solutions in aerospace, electronics, information systems, shipbuilding and technical services to government and commercial customers worldwide.
