South Korea's government has committed US$150 billion to revitalise American shipyards, with its leading builders launching major projects to boost domestic production and supply chain resilience, reported Forbes magazine.

Hanwha acquired Philly Shipyard for US$100 million in late 2024 and announced a $5 billion upgrade in August 2025. This investment will add two docks and three quays, raising annual output from fewer than two vessels to up to 20, including LNG carriers and naval modules.

Hanwha Ocean is introducing world-class automation at Philly Shipyard, while HD Hyundai has partnered with Cerberus Capital Management on a joint maritime investment programme. Samsung is collaborating with Vigor Marine Group in Oregon for naval maintenance and repair.

Analysts said the investment marks a pivot toward localised fleet replenishment and reduced reliance on overseas supply chains. Advanced automation and digital yard technologies are expected to compress lead times and stabilise Jones Act vessel availability.

The integration of South Korean technology transfer positions the US to compete in specialised sectors such as LNG transport, reshaping the future of maritime trade and strengthening resilience in global logistics.
