Shipbuilding on the Kennebec River
Shipbuilding has been a way of life along the Kennebec River in Bath, Maine, since 1762, when the sailing ship Earl of Bute was launched on the site of present-day Bath. Over the years, many shipyards have called Bath home, but Bath Iron Works remains the only shipyard that remains active today.
Our Beginnings
Bath Iron Works was the namesake of a brass and iron foundry established in 1826. Brigadier General Thomas W. Hyde took over the foundry in 1865, following service with the 20th Maine Regiment during the Civil War. Nearly two decades later, he incorporated his diversified marine business interests as Bath Iron Works, Limited in 1884 before expanding into shipbuilding with the acquisition of the Goss Marine Iron Works in 1888.
The first vessel delivered by BIW was a coastal passenger ship named Cottage City built for the Maine Steamship Co. Since the completion of Hull #1 in 1890, BIW has been awarded more than 425 shipbuilding contracts, over 245 military ships (mostly destroyers and frigates for the U.S. Navy) and over 160 private yachts and commercial vessels. BIW became a wholly-owned subsidiary of General Dynamics in 1995.
Lead Shipyard for DDG 51 Destroyers
In 1985, BIW won the competition for detail design and construction of USS Arleigh Burke (DDG 51), the Lead Ship for the Navy’s most capable class of AEGIS guided missile destroyers and the Workhorse of the Navy.
The DDG 51 program has become one of the longest-running shipbuilding programs for surface combatants in U.S. Navy history.

Building for a Better Tomorrow
Modernizing Our Shipyard
Under General Dynamics’ ownership, BIW teamed up with the City of Bath and the State of Maine to support a long-term capital investment plan which included the Land Level Transfer Facility, which was completed in 2001. These improvements enabled us to build the DDG 1000 class of destroyers, the Zumwalt class, the most technologically-advanced ship in the world.
Today, we continue to modernize our shipyard so that we can offer improved productivity, and affordability to our customer and continue delivering high-quality Bath-built ships.
