Defense contractor General Dynamics Electric Boat says it’ll need to hire thousands more employees over the next decade as it ramps up submarine production.

Electric Boat President Kevin Graney met with elected officials in Connecticut and Rhode Island for an annual legislative update on Monday. Graney says the company currently has nearly 17,000 employees — a level of employment not seen since 1993.

He says Electric Boat will need about 20,000 employees around 2030 to build two classes of submarines.

That will require hiring about 18,000 people to increase the headcount while accounting for attrition.
