CHARLOTTESVILLE, Va., June 20, 2005 -- Northrop Grumman Corporation (NYSE: NOC) unveiled its new BridgeMaster E 340(TM) navigation radar system at the Nor-Shipping 2005 conference in Lillestrom, Norway, earlier this month.

A product of Northrop Grumman's Sperry Marine business unit, this third-generation, flat-screen technology system incorporates all the features and performance of the current BridgeMaster E series and has been repackaged in Sperry Marine's new compact Vision FT(TM) cabinet. Its new styling, which has previously only been available for use in integrated bridge systems, is now available for stand-alone radar configurations.

The new Vision FT cabinet has been optimized for large, high-resolution flat-panel monitors, providing navigators with clear, crisp radar images. The radars also feature a totally new user interface incorporating a proprietary ergonomic trackball for improved control in all sea conditions, and a tactile control panel providing dedicated controls for the most important radar functions.

The new BridgeMaster E 340 is fully type approved for S-band, X-band, up-mast/down-mast transceiver configurations on both conventional and high-speed craft. It is also type approved in the dual-channel configuration, combining both S- and X-band returns into a single, integrated display.

As is common with all BridgeMaster E radars, the new system incorporates Sperry Marine's proprietary automatic clutter suppression technology.

Sperry Marine, with worldwide headquarters in Charlottesville, Va., and major engineering and support offices in Melville, N.Y., New Malden, United Kingdom and Hamburg, Germany, is part of Northrop Grumman's Electronic Systems sector.
