DynCorp has received a five-year, $35 million subcontract to provide operational support to the United States Naval Ship (USNS) Hayes and USNS Waters, Naval Special Mission ships that support test and range operations in Florida. The USNS Hayes, one of the acoustically quietest surface ships in the world, operates from Port Canaveral, Fla., and supports the U.S. Navy's underwater sound range at the Atlantic Undersea Test and Evaluation Center (AUTEC). Because of its special design, the Hayes is the only ship in the U.S. Navy capable of performing the full-spectrum of active and passive ship acoustic signature measurements required for new and recently overhauled Naval surface ships and submarines.
