WOODLAND HILLS, Calif., Oct. 5, 2005 (PRIMEZONE) -- Northrop Grumman Corporation (NYSE:NOC) has been selected by two commercial airlines to provide air-data inertial reference units for a combined fleet of up to 110 Airbus A320 aircraft.

A key benefit of Northrop Grumman's air-data inertial reference units is AIME(tm), which provides enhanced navigation capabilities, allowing the aircraft to take off and land in adverse weather conditions and in areas with poor GPS reception. The inertial reference unit provides air data, altitude, air speed and angle of attack information, as well as inertial accelerations and attitudes to the aircraft flight-management systems, flight instruments and autopilot.

Air Berlin and Niki have placed combined orders for triple systems (three inertial reference units per aircraft) on 70 aircraft and have options to equip 40 additional aircraft. Terms of the agreements were not disclosed.

Headquartered in Woodland Hills, Calif., Northrop Grumman's Navigation Systems Division -- part of the company's Electronic Systems sector -- supplies situational-awareness products for international and domestic defense and commercial markets and offers integrated avionics, navigation and positioning systems and sensors for space and high-value platform products, navigation-grade and tactical-grade inertial systems, fiber-optic gyro systems designed to customer requirements, underwater fiber-optic sensors, identification friend-or-foe transponders and interrogators, cockpit displays and computers, and logistics support products and services.
