Northrop Grumman won a contract by Bath Iron Works to supply commercial-off-the-shelf surface search radars for new Arleigh Burke (DDG 51) Class destroyers. Northrop Grumman's Marine Systems business unit, headquartered here, will supply the Decca BridgeMaster E naval radars for the next 19 ships in the class, replacing the SPS-64 radars installed on the earlier DDG 51 Class ships. The first installation is scheduled to take place on USS Mason (DDG 87), which will be commissioned in 2002. In addition to the radars, the contract also includes application engineering, installation, technical support, commissioning and crew training. Award of the navigation radar contract complements other Marine Systems navigation equipment aboard the DDG 51 Class ships.
