The Future of American Shipbuilding

Hanwha Philly Shipyard, Inc. (HPSI) is a premier U.S. shipbuilder supporting commercial and government shipbuilding, located in Philadelphia’s historic Navy Yard. For nearly 30 years, we have delivered Jones Act–compliant vessels, that support U.S. commerce, energy security, and national defense.
Backed by the global strength of Hanwha Group, HPSI is expanding America’s shipbuilding capacity and helping shape the future of the U.S. maritime industry.

Our state-of-the-art shipyard and highly skilled American workforce, supported by integrated engineering, production planning, and quality assurance disciplines, have earned a reputation for safety, reliability, and exceptional craftsmanship.

From commercial operators to U.S. government agencies, customers trust HPSI to deliver complex vessels to the highest industry standards.
