BATH — Maine’s two U.S. senators are applauding a $6.7 million contract so Bath Iron Works can perform additional engineering services on the design and construction of the U.S. Navy’s Zumwalt class destroyer.

Sens. Olympia Snowe and Susan Collins, both Republicans, say the money from the Department of the Navy will allow the team at the Bath shipyard to continue the critical engineering work.

They say the award is another reminder that the Bath Iron Works remains the crown jewel of the Navy’s shipbuilding base.
