Northrop Grumman Corporation (NYSE: NOC) has won a contract from the Canadian government to supply advanced inertial navigation systems for its four Victoria-class submarines.

The firm, fixed-price contract, valued at $9.7 million, was awarded to Northrop Grumman’s Sperry Marine business unit.

Sperry Marine will supply MK49 ring laser gyro (RLG) systems and new-generation navigation distribution systems for the four submarines. The installations will be performed during 2005 and 2006.

The MK49 is a ship’s inertial navigation system (SINS) based on Sperry Marine’s unique RLG technology. It provides highly accurate position, attitude, velocity and heading inputs to ships’ navigation and fire-control systems. The Sperry Marine navigation distribution system integrates data from the SINS and other shipboard sensors.

Sperry Marine is a world leader in RLG technology, having supplied more than 80 percent of the systems at sea today. The MK49 is the standard RLG equipment used on NATO ships, including the Canadian Halifax- and Iroquois-class vessels.
