PHILADELPHIA — A historic South Philadelphia manufacturing site is undergoing a seismic shift. Backed by a $5 billion infrastructure and modernization commitment from South Korean conglomerate Hanwha Group, the Hanwha Philly Shipyard is racing to transform how vessels are built in the United States.
Following its initial $100 million acquisition of the shipyard, Hanwha is doubling its footprint at the Philadelphia Navy Yard. The goal is as ambitious as the price tag: taking an industrial yard that previously produced one or two ships a year and scaling its output to up to 20 vessels annually within the next decade.
Bringing South Korean Automation to South Philly
To pull off that tenfold jump in capacity, Hanwha is overhauling the mechanics of American shipbuilding. Rather than relying solely on traditional methods, the company is importing the advanced manufacturing playbook it perfected at its massive yards in South Korea.
- Smart-Yard Infrastructure: The $5 billion injection funds the construction of two additional docks, three new quays, and an expanded block assembly facility.
- Robotics & Digital Twins: Hanwha is installing automated robotic welding systems, digital-twin modeling, and automated inspection technology adapted directly from its Korean operations.
- Cross-Pacific Workforce Training: To ensure local tradespeople can operate the specialized equipment, Hanwha has brought in Korean trainers to instruct the Philadelphia workforce on high-efficiency, automated production techniques.
What They're Building
The rapid buildout comes as federal and commercial demand for domestic shipbuilding hits a critical turning point. Operating under the Jones Act—which requires vessels transporting goods between U.S. ports to be built, flagged, crewed, and owned domestically—the yard's order book is expanding into new territory:
- National Security Multi-Mission Vessels (NSMV): Backed by federal orders, these specialized ships serve as training platforms for federal maritime academies and first-responder lifelines during natural disasters.
- Jones Act LNG Carriers: Hanwha has initiated orders for domestic Liquefied Natural Gas (LNG) carriers—bringing commercial LNG shipbuilding back to the U.S. market for the first time in nearly 50 years.
- Medium-Range Tankers: The yard is tasked with building a fleet of 10 chemical and oil tankers to support domestic energy transportation and supply chain resilience.
- Naval Modules & MRO: In the longer term, Hanwha plans to use the Philadelphia facility for naval defense auxiliary construction and Maintenance, Repair, and Overhaul (MRO) operations.
A Manufacturing Boom for Pennsylvania
For the region's labor market, the operational ramp-up is already being felt on the ground. Hanwha has more than doubled the shipyard's workforce since taking control and poured over $200 million into facility upgrades within its first year alone.
In total, the long-term expansion is projected to create thousands of skilled labor jobs at the shipyard, alongside thousands of additional indirect jobs across the Greater Philadelphia supply chain.
"Philly Shipyard is a proven asset in the U.S. maritime industry, and our goal is to combine that strong foundation with world-class processes and technology to create the most advanced shipyard in the world," said Dong Kwan Kim, Vice Chairman of Hanwha Group.
With new docks rising along the Delaware River and a state-accredited apprenticeship program funneling new talent onto the yard, the South Philadelphia waterfront is positioning itself as the epicenter of America's maritime industrial revival.
