• Former President Donald Trump and South Korea announce a landmark $150 billion shipbuilding initiative, the "Make America Shipbuilding Great Again" (MASGA) campaign, as part of a broader trade pact.
  • The deal reduces U.S. tariffs on South Korean imports from 25% to 15% and includes a total South Korean investment package of $350 billion in the U.S.
  • South Korean giants Hanwha Ocean, HD KSOE, and Samsung Heavy Industries are central to the effort, which aims to revitalize the U.S. industrial base and counter China's dominance in global shipbuilding.

In a move that signals a major strategic shift in global industrial policy, former President Donald Trump and South Korea have unveiled a sweeping agreement centered on a $150 billion effort to revitalize American shipbuilding. The "Make America Shipbuilding Great Again" (MASGA) campaign forms the core of a new U.S.-South Korea trade pact designed to deepen bilateral industrial and defense ties while directly addressing China's commanding 60-67% share of the global shipbuilding market.

The agreement, which also sees South Korea commit to a total investment package of $350 billion in the U.S. and to buy $100 billion of U.S. energy, reduces steep U.S. tariffs on South Korean imports from 25% to 15%. In return, the partnership leverages South Korea's formidable 22% global market share and its leading shipbuilders—Hanwha Ocean, HD KSOE, and Samsung Heavy Industries—to modernize aging U.S. shipyards and transfer critical technology.

This is not a theoretical deal; the groundwork is already being laid. Hanwha Ocean’s recent acquisition of the Philly Shipyard is a key part of the strategy, with the first U.S.-built LNG carriers from that facility targeted for delivery by 2028, according to people familiar with the company's plans. The move is seen as a crucial first step in jumpstarting domestic production of complex, high-value vessels that have largely been ceded to foreign yards for decades.

“What we are seeing is a fundamental realignment of economic and security priorities,” said one advisor briefed on the negotiations. “This is about building a resilient, allied-based supply chain for both commercial and military vessels that doesn’t run through Beijing.” The deal aligns with legislative efforts underway to enable U.S. allies, including Japan, to build and service American military and commercial ships, a significant departure from longstanding protectionist procurement rules.

For South Korea’s shipbuilding titans, which are already reporting strong order backlogs for LNG carriers and naval contracts, the influx of U.S. investment and guaranteed access to the American market is expected to provide a substantial boost to revenues and their international profiles. The partnership model, which often involves Korean firms working alongside U.S. yards rather than outright replacing them, is designed to mitigate potential political friction over outsourcing.

The pact delivers on a core Trump campaign promise to rebuild American manufacturing and bolster the U.S. Navy's fleet. It mirrors previous efforts to revive industries like steel and coal through a combination of protectionist measures and deals with allied nations. Proponents argue it will create U.S. jobs and secure the nation's maritime industrial base, though critics are likely to question the scale of foreign involvement and potential for labor disputes. Efforts to reach representatives from the major Korean firms for comment were not immediately successful.

The ultimate success of the MASGA campaign will depend on its ability to overcome decades of industrial decline. The U.S. shipbuilding industry now accounts for less than 1% of global output, a stark drop from its post-WWII prominence. If successful, however, the model could be applied to other critical sectors, such as semiconductors, where the U.S. is also seeking to build allied supply chains to reduce reliance on China.
