President Donald Trump of the United States has suggested that shipbuilders from South Korea might play a key role in enhancing and expanding the US Navy’s fleet, hinting at the potential purchase of ships constructed outside American borders. At the Pennsylvania Defense and Innovation Summit, Trump underscored the importance of modernizing the nation’s aging naval vessels, stating that Washington is exploring increased collaboration with South Korean firms and other international partners.
Among the initiatives discussed is a plan to construct two National Security Multi-Mission Vessels at Hanwha Philly Shipyard in Philadelphia, a project estimated to be worth around $1.5 billion. This move is part of a wider trend of growing defense ties between the US and South Korea. Recently, South Korean President Lee Jae Myung disclosed that Trump inquired if South Korea could swiftly build 10 naval ships for the US, a topic that has been a focal point in recent international discussions.
The US Department of Defense and the Navy have reached out to major South Korean shipbuilders, specifically HD Hyundai Heavy Industries and Hanwha Ocean, to evaluate their ability to design and produce combat vessels. Hanwha, having acquired shipyard facilities based in Philadelphia in 2024, is seen as strategically well-placed to capitalize on this partnership. The company is also pursuing licenses to manufacture military ships within the US. Meanwhile, HD Hyundai and Samsung Heavy Industries have forged deeper partnerships with American enterprises, aiming to penetrate the US naval shipbuilding industry.
Despite the promising collaboration with South Korean shipbuilders, there are significant legal challenges to overcome. Current US laws limit the construction of Navy vessels to within the country, meaning any agreement to build ships overseas would necessitate legislative changes or special exemptions. This legal framework presents a complex hurdle that must be addressed for the proposed international shipbuilding cooperation to proceed.
