CHARLOTTESVILLE, Va., June 21, 2005 -- Northrop Grumman Corporation (NYSE: NOC) has won a contract from General Marine Business Inc. Korea (GMB) to supply an integrated cockpit navigation and control system for the Republic of Korea Navy's new LSF-II program, a high-speed hovercraft landing ship.

The firm fixed-price commercial contract, valued at $5.6 million, for the delivery of the first two craft in 2006, was awarded to Northrop Grumman's Sperry Marine business unit.

Sperry Marine's Integrated Navigation and Ship Control (INSC) solution will integrate navigation and engineering sensor data to present the hovercraft operator and navigator with a composite visual representation on workstations to enhance their situational awareness. Specially designed man-machine interface screens and a universal keyboard system allow the crew members to quickly and easily evaluate the information and operate the system, even in the most demanding operational and environmental conditions.

The INSC system will include the hardware and software for Sperry Marine's electronic-charting Voyage Management System and BridgeMaster radar, as well as a platform control and alarm monitoring system. The system includes tailored naval features for mission planning and analysis and data recording capability, as well as enhancements for high-speed operations.
