BALTIMORE, Nov. 17, 2011 -- Northrop Grumman Corporation (NYSE:NOC) recently held its first Ground Based Radar Conference focused on developments in ground radar technologies for national defense.

"Ground radars play a critical and growing role in national security for our international partners," said John Johnson, sector vice president and general manager of Northrop Grumman's Intelligence, Surveillance and Reconnaissance (ISR) Systems Division. "The conference gave us an opportunity to discuss the changing needs of our customers and to brief them on our solutions to emerging threats."

Attendees also had the opportunity to view demonstrations of some of Northrop Grumman's latest ground radar systems.

The conference featured a keynote speech by retired U.S. Air Force Gen. Charles A. Horner, former Commander in Chief of North American Aerospace Defense Command, who provided his unique perspective into the ever-changing CONOPS (concept of operations) of today's military and the importance of ground-based radars to national defense.

"With any nation, its primary responsibility is the sovereignty of air space. You have to have radar mobility, survivability, reliability and maintainability," Horner said.

Robert Royer, vice president of International Systems at Northrop Grumman's ISR Systems Division, outlined the company's legacy ground radar heritage, beginning with the installation of the SCR-270 radar at Pearl Harbor. He culminated with a description of how Northrop Grumman's ground based radar systems and capabilities have adapted to evolving threats over time to ensure their continued relevance into the future.

Three in-depth panel discussions rounded out the final day of conference presentations, allowing the attendees to join a discussion focused on the changing surveillance landscape of current and emerging threats, including next-generation fighters, unmanned air vehicles, cruise missiles and theater ballistic missiles.

Northrop Grumman's current ground radar systems include the AN/TPS-78 and TPS-703 solid-state tactical mobile radar systems; the Highly Adaptable Multi-Mission Radar (HAMMR), a compact, multimode ground radar that uses airborne active electronically scanned array technology to provide on-the-move, 360 degree coverage; and the multimission AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR), which replaces five legacy U.S. Marine Corps ground-based radars.
