ORLANDO, Fla., May 5, 2010 -- Northrop Grumman Corporation (NYSE:NOC) announced today that it intends to bid as prime contractor for the U.S. Army Range Radar Replacement Program (RRRP) competition.

The RRRP procurement will be managed by the Army Program Executive Office for Simulation, Training and Instrumentation. The program will replace aging and outdated radar systems at four test centers: White Sands Missile Range, N.M.; Yuma Proving Ground, Ariz.; Aberdeen Test Center, Md.; and Redstone Test Center, Ala. These ranges are used for testing U.S. Department of Defense weapons systems, and much of the range radar inventory consists of 1950s and 1960s-vintage radars that no longer adequately meet current and emerging test requirements. The RRRP will focus on implementing modern radar technologies and developing a common architecture to significantly improve performance while reducing the overall life cycle costs.

"The Army has a critical need to enhance the test effectiveness of its test ranges and lower the cost of radar operation and maintenance," said Karen Williams, vice president of Air and Missile Defense Systems for Northrop Grumman's Information Systems sector. "Northrop Grumman will draw upon its decades of experience pioneering radar technology and open architecture, system-of-systems solutions to meet the Army's objectives."

Northrop Grumman is a leading provider of radar systems and is expert in their design, hardware and software development, manufacturing, operations and maintenance. The company's core competencies include radar data processing, algorithm development and modeling and simulation. Northrop Grumman has more than 40 years experience fulfilling range radar requirements such as radar design, pre-mission planning and post-mission analysis. The company led a team to design and manufacture range radars for the U.S. Navy and has been responsible for operating and maintaining the radars at Cape Canaveral for the NASA debris monitoring system since its inception.

Further, Northrop Grumman will leverage its extensive net-centric, large-scale systems integration expertise to ensure a comprehensive, interoperable solution that addresses the broad range of performance requirements for this competition.
