Navy Orders More Underwater Drones From Huntington Ingalls | The Motley Fool

Navy shipbuilder Huntington Ingalls (NYSE:HII) announced Tuesday that the United States Navy has ordered two REMUS 300 unmanned underwater vehicles "to support their critical national security missions." No price was stated for the order.

REMUS UUVs -- small, unmanned, robotic submarines -- come in a variety of sizes, and the "number" of the unit's name refers to the maximum depth (in meters) to which they can dive. The Navy has historically used them for missions including search and rescue (locating ships and aircraft that have sunk beneath the ocean) as well as for mine detection. During Operation Iraqi Freedom in 2003, for example, the Navy used REMUS drones to assist in minesweeping in the Persian Gulf.
