Northrop Grumman Corporation's LN-200 inertial measurement devices will be used to increase the capabilities of the U.K. Ministry of Defence's Sting Ray torpedo. Under a 10-year contract awarded recently by BAE SYSTEMS' Underwater Systems Division, Northrop Grumman's Navigation Systems Division will provide LN-200s for the torpedo, which is being modified to defeat the dual threats of both fast, deep diving, double-hulled submarines operating in the ocean and quiet conventional submarines in coastal waters. "The LN-200 provides a compact, low-power and low-radiated noise inertial measurement unit that fulfils the unique environmental and low maintenance needs of the Sting Ray torpedo," said Ross Carr, LN-200 program manager at Northrop Grumman.
