US President Donald Trump has suggested expanding the role of South Korean shipbuilders in modernizing the US Navy, potentially opening the door to purchasing ships constructed outside the United States. During his remarks at the Pennsylvania Defense and Innovation Summit, Trump underscored the importance of updating the country’s aging naval fleet and mentioned the possibility of enhanced collaboration with South Korean companies and other international partners.
In a move highlighting this cooperation, Trump announced plans to construct two National Security Multi-Mission Vessels at Hanwha Philly Shipyard in Philadelphia, a project valued at about $1.5 billion. This development comes as defense ties between the United States and South Korea continue to grow. Notably, South Korean President Lee Jae Myung shared that Trump inquired if South Korea could swiftly build 10 US naval vessels, a topic that has been explored further in recent international discussions.
The Pentagon and the US Navy are currently assessing the capabilities of major South Korean shipbuilders. They have sought input from companies like HD Hyundai Heavy Industries and Hanwha Ocean to evaluate their expertise in designing and constructing combat ships. Hanwha, in particular, stands to gain from this potential partnership, having acquired shipyard facilities in Philadelphia in 2024 and seeking licenses to produce military vessels in the US. Simultaneously, HD Hyundai and Samsung Heavy Industries have strengthened their alliances with American firms to penetrate the US naval shipbuilding sector.
Despite the promising developments, significant legal obstacles need to be addressed. Current US laws restrict the construction of Navy ships abroad, meaning any overseas production would necessitate legislative approval or specific exemptions. This legal framework presents a considerable challenge to the proposed international collaboration, though the ongoing discussions reflect a serious consideration of potential changes.
