Who We Are

“Bath Built Is Best Built” ®



Design, build and support the highest-quality surface combatants for the United States.


An exceptional maritime company that safely provides shipbuilding, component manufacturing and specialized services with a world-class team and facilities.

Part of General Dynamics Marine Systems, Bath Iron Works is a full service shipyard specializing in the design, building and support of complex surface combatants for the U.S. Navy. BIW’s rich history reflects a continuous pattern of innovation, new technology and process improvements.

Today, we are revolutionizing naval shipbuilding. We are substantially reducing the labor hours needed to build Navy warships by producing highly outfitted modular ship units, some weighing nearly 4,000 tons, which are erected on our state-of-the-art Land Level Transfer Facility. OpEx and Lean Manufacturing practices are widespread. The result is a highly capable and affordable product for our Navy that carries with it the renowned quality of a Bath-built ship.

Our employees are our strength. We are shipfitters, welders, electricians, fabricators and pipefitters. We are program managers, designers, naval architects, engineers, ship operators and business professionals. We come from all over the US and from all walks of life and each day we contribute to the defense of our nation.

We are one of the largest private sector employers in Maine. As such, we play a key role in the economic growth and stability in the Midcoast region and beyond. BIW is the lead designer and builder of the Arleigh Burke (DDG 51) class of AEGIS destroyers, the most successful Navy new ship construction program of recent decades. These ships are the most technologically advanced surface combatants afloat. Since 1884, we have continued our tradition of leadership in technology and innovation.
