Electric Boat project designed to modernize shipyard

General Dynamics Electric Boat on Tuesday began the renovation of graving docks 1 and 2 at its shipyard, which will enable the company to build upon its submarine-repair capabilities and help retain its workforce in Connecticut. The two-year project will cost $65 million. The docks are used for new submarine construction as well as submarine maintenance and modernization work. Electric Boat is a wholly owned subsidiary of General Dynamics.
