CHARLOTTESVILLE, VA - June 18, 2004 - Northrop Grumman Corporation's (NYSE: NOC) Sperry Marine business unit has introduced its new-generation NAVIGAT X MK 2 digital gyrocompass system to provide a cost-effective solution that satisfies international carriage requirements for a type-approved marine gyrocompass.

The NAVIGAT X MK 2 gyrocompass is a compact, one-unit design that runs on a 24-volt power supply with two independent DC inputs. It provides five serial data outputs and one six-steps/degree output, and can drive up to four analogue repeaters. Based on the proven Sperry Marine NAVIGAT X MK 1 design, the new gyrocompass provides better than 40,000 hours mean time between failures. The system remains north-stabilized for up to three minutes in the event of a power interruption.

The NAVIGAT X MK 2 complies with International Maritime Organization (IMO) regulations A.424(XI) and A694(17) and the International Standards Organization (ISO) standard 8728, and is fully Wheelmark type-approved.

The introduction of this new gyrocompass completes the Sperry Marine range of heading sensors, which includes the NAVIGAT 2100 fiber-optic gyrocompass, NAVIGAT X MK 1 and NAVIGAT X MK 2 digital gyrocompasses and NAVISTAR I and NAVISTAR II satellite compasses.
