The US Navy has awarded a contract to General Dynamics Electric Boat to provide management support of nuclear-maintenance work for submarines docked at the Naval Submarine Base in Groton.

The three-year contract is worth $78m if all options are exercised.

Under the contract, the company will provide project management, planning, training and radiological-control services to support maintenance, modernisation and repairs.

The contract allows Electric Boat to continue operating the nuclear regional maintenance department at the submarine base.
