WOODLAND HILLS, Calif., Feb. 2, 2009 -- Northrop Grumman Corporation's (NYSE:NOC) LN-270 inertial navigator, a pointing-locating-navigating system, has been selected to support upgrades of additional U.S. Army AN/TPQ-48(V)2s (Lightweight Counter Mortar Radar) under a contract for LN-270 inertial navigation systems and non-recurring engineering from SRCTec, Inc.

AN/TPQ-48(V)2 is a man-portable ground radar that autonomously detects the firing positions of short range mortars and predicts the area the ordnance will impact. The LN-270 units will provide enhanced capability to the AN/TPQ-48(V)2 to aid in locating hostile indirect fire.

"Northrop Grumman is proud our LN-270 units are keeping our Warfighters safe," said Jim Myers, sector vice president and general manager of Northrop Grumman's Navigation Systems division. "The units delivered under this contract will spread this protection to additional Soldiers operating under the protection of the AN/TPQ-48(V)2 when LN-270 upgrades are installed."

The Global Positioning System (GPS) in the LN-270 provides very precise pointing information to the radar system. The LN-270 was selected for the AN/TPQ-48(V)2 based on its high accuracy, selective availability/anti-spoofing module-compliant GPS, low power consumption, and lightweight design.

Northrop Grumman Corporation is a leading global security company whose 120,000 employees provide innovative systems, products, and solutions in aerospace, electronics, information systems, shipbuilding and technical services to government and commercial customers worldwide.
