Exploring the Hurdles Facing Trump's Proposed US Shipbuilding Spree
The Trump administration has proposed a sweeping expansion of US commercial shipbuilding, including executive orders directing federal agencies to prioritise domestic vessel construction, tariff measures targeting foreign-built vessels calling at US ports, and proposed legislation to revitalise the Jones Act fleet. The stated objective is to rebuild America's commercial shipbuilding capacity, which has declined to a fraction of its Cold War peak. The ambition is significant. The hurdles are substantial.
How Far Has US Shipbuilding Declined?
The United States currently delivers fewer than five large commercial vessels per year from its domestic shipyards. By contrast, South Korea, China, and Japan collectively deliver over 2,500 vessels annually, accounting for more than 90 percent of global commercial shipbuilding output by gross tonnage. US yards — Philly Shipyard, General Dynamics NASSCO, and Huntington Ingalls Industries — focus primarily on Jones Act tonnage and naval construction, with limited capacity for internationally competitive commercial builds.
The cost differential is stark. A Jones Act MR product tanker built in the United States costs approximately $300 million, compared to $65 to $70 million for an equivalent vessel from a Korean yard. This four-to-one cost ratio reflects higher labour costs, lower productivity, limited supplier ecosystems, and the absence of the series production efficiencies that Asian yards have perfected over decades.
What Are the Workforce Challenges?
The most immediate constraint is labour. US shipyards employ approximately 150,000 workers, the majority in naval construction. Scaling commercial output would require tens of thousands of additional welders, pipefitters, electricians, marine engineers, and project managers — skills that take years to develop.
The Bureau of Labor Statistics projects a national shortage of over 500,000 skilled trades workers by 2028 across all construction sectors. Shipbuilding must compete for this talent against infrastructure construction, energy sector projects, and semiconductor fabrication facility buildouts — all of which are simultaneously scaling under separate federal initiatives.
Apprenticeship programmes at major US yards typically require three to four years to produce a journey-level shipfitter. Even with immediate investment in training capacity, meaningful workforce expansion would not materialise before 2029-2030.
What About Shipyard Infrastructure?
US commercial shipyard infrastructure has atrophied over decades of declining activity. Drydock capacity, crane installations, steel processing facilities, and outfitting berths have not been maintained or expanded at the scale required for high-volume commercial production.
The Department of Transportation's Maritime Administration has identified approximately $2 billion in deferred maintenance and capital investment needs across the domestic shipyard base. Modernising existing facilities and building new capacity — including potentially greenfield yards — would require sustained federal investment over a decade or more.
Supply chain development is equally critical. Asian shipbuilding competitiveness depends on dense, proximate supplier networks that provide marine equipment, coatings, propulsion systems, and navigation electronics on a just-in-time basis. US marine equipment manufacturers have either consolidated, offshored production, or exited the market. Rebuilding this supplier ecosystem is a prerequisite for cost-competitive domestic construction.
How Do Tariff Measures Affect the Equation?
The administration's proposed tariffs on foreign-built vessels calling at US ports are designed to create economic incentives for US construction. However, the practical impact depends on implementation details that remain unclear. US-flag international trading vessels — a fleet of fewer than 80 ships — already face cost structures that make them uncompetitive on most global trades. Additional tariffs on foreign-built tonnage could increase costs for US importers and exporters without generating sufficient demand to justify domestic shipyard expansion.
The Jones Act fleet, which requires US-built, US-flagged, and US-crewed vessels for domestic waterborne commerce, is the more natural market for expanded domestic production. However, Jones Act fleet renewal has been constrained by the very cost premiums that reflect the current state of US shipbuilding — creating a circular problem.
What Would Success Look Like?
Realistic assessments from industry analysts suggest that a sustained, bipartisan industrial policy commitment of 15 to 20 years, combined with federal capital investment on the order of $20 to $30 billion, could rebuild US commercial shipbuilding capacity to a level where domestic yards deliver 20 to 30 vessels annually — a meaningful increase, but still a small fraction of global output.
Conclusion
The administration's shipbuilding ambitions address a real strategic vulnerability. The United States depends on seaborne commerce for over 40 percent of its trade by value, yet has virtually no capacity to build the vessels that carry it. Closing this gap is a generational industrial challenge requiring workforce development, infrastructure investment, supply chain reconstruction, and sustained political commitment. The hurdles are formidable, but the strategic case for a stronger domestic shipbuilding base is difficult to dispute.
