Submarine manufacturer Electric Boat in Connecticut has won U.S. Navy contracts worth $25 million for maintenance on the USS Annapolis in Groton and to support repairs on nuclear submarines and carriers at Puget Sound Naval Shipyard in Washington state.

Connecticut Sens. Joe Lieberman and Richard Blumenthal and Rep. Joe Courtney said Tuesday the Annapolis maintenance and upgrade project will be conducted this fall at the Groton site of Electric Boat, a division of General Dynamics Corp. It's expected to employ up to 225 workers.

The Puget Sound contract will require about 60 workers.
