CHARLOTTESVILLE, Va., Oct. 31, 2006 (PRIMEZONE) -- Northrop Grumman Corporation (NYSE:NOC) has been awarded a contract from the Brazilian Navy for the second phase of a multi-year retrofit acquisition program to upgrade the primary navigation systems on its combat ships.

The ship inertial navigation systems (SINSs) will be supplied by Northrop Grumman's Sperry Marine business unit.

Sperry Marine will supply eight new-generation MK39 ring-laser gyro (RLG) systems plus supporting interfaces, accessories and spares.

The new systems will provide high-accuracy position data and precise attitude, velocity and heading inputs for the ships' navigation and fire-control systems.

Nolasco DaCunha, director of Sperry Marine Systems. "The Phase II SINS program builds on Sperry Marine's longstanding relationship with the Brazilian Navy, dating back more than 30 years."
