CHARLOTTESVILLE, Va., Jan. 15, 2002 (PRIMEZONE) -- Northrop Grumman Corporation's (NYSE:NOC) Sperry Marine unit has been awarded a contract by BAE SYSTEMS to supply inertial navigation systems for three new Astute-class submarines for the U.K. Royal Navy.

Each of the new submarines will be fitted with dual enhanced NATO Ship's Inertial Navigation Systems based on Sperry's ring laser gyro (RLG) systems technology. Equipment deliveries under the $5.8 million contract are scheduled to begin in late 2002 and will be completed in 2004.

The RLG systems provide highly accurate navigation inputs and precise attitude and heading data for weapons control and combat management systems.

The first of the new 7,200-ton, 318-ft. Astute-class nuclear attack submarines will be launched in 2004. The Ministry of Defence has ordered six of these submarines, which will replace the existing Swiftsure-class and early Trafalgar-class boats. A follow-on contract for the remainder of the Astute-class platforms is expected in 2002.

Sperry Marine is a leading supplier of RLG technology for the U.S. Navy and 30 international navies. The business unit is currently retrofitting the U.S. fleet of surface combatants and nuclear attack submarines with the new-generation AN/WSN-7 and AN/WSN-7B RLG inertial navigation systems under a multi-year program. Sperry Marine has also supplied the exportable MK39 series RLG systems to many of the world's navies, including Australia, Brazil, Greece, Kuwait, Mexico, Oman, Singapore, Spain and Taiwan.
