LINTHICUM, Md., June 21, 2010 -- Northrop Grumman Corporation (NYSE:NOC) has marked a significant milestone in the development of advanced surface warfare radars with the successful live outdoor testing of the company's S-band radar testbed.

Northrop Grumman successfully conducted live outdoor testing at the company's Linthicum test range, tracking aircraft and other targets of opportunity with its S-band radar testbed, while demonstrating key advanced S-band radar technologies, including distributed receivers and digital beam forming.

Northrop Grumman's S-band radar is being developed to provide the U.S. Navy with significantly enhanced capabilities to detect, track and engage ballistic missiles while simultaneously performing anti-air warfare in high clutter environments. Such a capability is critical to meeting the Navy's increased requirements to provide integrated air and missile defense for both the United States and its allies.

"At Northrop Grumman, we are focused on using our extensive technical expertise, operational knowledge and manufacturing capabilities to lower radar system development risks and costs through accelerated testing to ensure delivery of this critical defensive system to the Navy as soon as possible," said Steve McCoy, vice president of the advanced concepts business unit for the company's Electronic Systems sector. "This represents a significant accomplishment in the development of our solution for the Navy's ongoing Air and Missile Defense Radar (AMDR) competition."

In addition, Northrop Grumman successfully tested the latest generation of ballistic missile defense T/R modules, which is the key technology necessary to meet the AMDR program requirements. AMDR represents the next generation radar system planned for the Navy's Future Surface Combatant platform. Northrop Grumman's modular, open architecture approach provides the ability to scale the radar system to accommodate multiple ship classes.
