Bath Iron Works has received a $13 million award from the Navy to modify existing contract work on Arleigh Burke-class destroyers.

The money will be used to upgrade design services to replace one radar system with another on the warships. A similar award was made to the Huntington Ingalls shipyard in Mississippi.

Five destroyers are currently being built at the Bath yard. The Naval Sea Systems Command in Washington awarded the $13,027,540 contract.
