BATH — United States Senator Susan Collins (R-Maine) and U.S. Congresswoman Chellie Pingree (D-Maine) announced Tuesday that Bath Iron Works has been given a $70 million contract that will allow the Maine shipyard to continue to design, plan and modernize the Navy’s fleet of warships for at least another year.

The contract impacts BIW’s work on the DDG-51 Arleigh Burke line of guided missile destroyers, which began in Bath in 1989, as well as the FFG-7 Oliver Perry class guided missile frigate, a warship that was launched in 1975.

“This contract represents $70 million of work at the yard next year, which is important to keep some of the best shipbuilders in the world on the job,” Pingree said in a statement.

“It (the contract) also represents the Navy’s continuing commitment to the surface fleet, which is crucial for the future of the Navy and of our national security,” Collins said.
