PORTLAND, Maine (AP) — A Wisconsin shipbuilder has won a contract to build up to 10 frigates for the Navy. The $795 million contract calls for Fincantieri Marinette Marine to move forward with design and construction of the lead ship with options for up to nine more frigates. Officials say the contract carries a value of $5.6 billion if all 10 ships are built. The Navy pressed to expedite the process by asking shipyards to use existing ship designs. Three other shipyard were finalists: General Dynamics’ Bath Iron Works in Maine, Austal USA of Alabama, and Huntington Ingalls of Mississippi.
