US Shipbuilding Revival 2026: The Jones Act Fleet, Korea, and the 381 Ship Question

The 295 ship fleet and the 381 ship target #

The US Navy battle force stood at 295 ships at the end of March 2025 according to the Naval Vessel Register, the lowest active count since the late 1990s. The fiscal year 2025 Shipbuilding and Conversion budget came in at USD 32.4 billion, funding two Virginia class submarines, two Arleigh Burke flight III destroyers, one Constellation class frigate, one Columbia class SSBN, one San Antonio class LPD, and a mix of auxiliaries and unmanned platforms. The 2024 30 year shipbuilding plan transmitted in March 2024 sets a long range ceiling of 381 manned ships by fiscal 2054, against which the current baseline is roughly 86 hulls short.

Closing that gap requires sustained delivery rates the current industrial base cannot generate. CBO's December 2024 analysis estimated annual shipbuilding costs averaging USD 40 billion in 2024 dollars over the thirty year window, roughly 25 percent above the historical average, and concluded that the Navy understates likely costs by 13 to 17 percent. The political ceiling sits in the armed services committees. The physical ceiling sits in six prime yards: HII Newport News (carriers and Virginia modules), HII Ingalls Pascagoula (Arleigh Burke, San Antonio, America class), GD Bath Iron Works (Arleigh Burke), GD Electric Boat (Virginia and Columbia), Austal USA Mobile (LCS, EPF, T-AGOS), and Fincantieri Marinette Marine (Constellation). Each carries a hard envelope set by drydock count, panel line throughput, and skilled trades headcount.

Constellation, Columbia, Virginia: the program triangle #

The Constellation class FFG-62 is the most exposed schedule risk in the surface combatant portfolio. GAO reported in August 2024 that Marinette Marine had reached only 25 percent design completion at the point construction had been scheduled to begin, that the lead ship would deliver three years late, and that cost growth had reached USD 2.1 billion. The original premise was to adapt the Italian FREMM design with minimum modification. The actual modification share rose above 85 percent once combat system, propulsion, and survivability requirements were applied, leaving a one off design carrying a parent design schedule.

Columbia class is the highest priority program in the budget. The first boat, USS District of Columbia, is running 12 to 16 months late against a 2027 first patrol target, with structural and software integration as the principal sources of slip. Columbia consumes Electric Boat throughput that would otherwise build Virginia hulls, a structural reason combined Virginia delivery rate has stalled near 1.2 boats per year against the FY26 budget assumption of 2.0. PEO Submarines has stated publicly that 2.33 Virginia deliveries per year by 2028 is required to honor AUKUS Pillar 1 transfer commitments without drawing from US Navy attack submarine inventory.

Closing this gap drives the entire submarine industrial base policy stack. Quincy Submarine Industrial Base initiative cumulative spend reached USD 5.4 billion through FY25 and is projected to reach USD 14 billion by 2030, funding tier two through tier four supplier expansion, workforce training, and digital thread investments. AUKUS partner contributions, including the Australian USD 3 billion capability injection, layer onto this base. The November 2025 CRS report concludes that 1.4 Virginia boats per year by 2027 is plausible, and that 2.33 per year is not credible before 2030.

The Jones Act fleet and the commercial collapse #

The US flag, US built, US crewed self propelled commercial fleet over 1,000 gross tons stood at 92 vessels in MARAD's 2024 inventory, against 193 in 1990 and 257 in 1980. The average age sits at 21 years versus a global commercial average closer to 12. Composition is unbalanced. Roughly 60 of the 92 hulls are product tankers and chemical carriers serving the Hawaii, Alaska, and Puerto Rico trades. There are no large container ships in active Jones Act service above 4,000 TEU. The largest US flag containerships in domestic trades are the Matson Aloha class at roughly 3,600 TEU, delivered by Philly Shipyard in 2018 and 2019.

There are zero Jones Act compliant LNG carriers. Movement of LNG between US ports requires a Jones Act qualified hull, and no current US yard can build a membrane type LNG carrier of the size moving in international trade. Puerto Rico, New England, and the Pacific Northwest therefore import LNG when domestic gas could be moved by sea if a hull existed. The 2024 GAO report on Jones Act LNG noted that new construction at a US yard would run roughly three to four times the comparable Korean yard price, an economic gap that no Jones Act freight premium is likely to close without explicit subsidy.

The SHIPS for America Act introduced by Senators Mark Kelly and Roger Wicker in April 2024 proposes a USD 250 billion ten year envelope across federal procurement of US flag tonnage, yard recapitalization grants, mariner training, and a Maritime Security Trust Fund seeded by tonnage taxes and tariff offsets. The headline target is 250 US flag commercial vessels in international trade by 2034, roughly triple the current internationally trading US flag fleet of approximately 80 hulls. The bill carries Republican and Democratic cosponsors with companion House language under Representatives Trent Kelly and Mike Waltz, and implementation will run through MARAD, the Federal Maritime Commission, and DOD Sealift.

Hanwha at Philly, HD Hyundai with HII, Mitsubishi inbound #

Korean and Japanese capital is the operative variable in the 2026 commercial recovery story. Hanwha Group, through Hanwha Ocean (formerly Daewoo Shipbuilding), closed its acquisition of Philly Shipyard from Aker ASA in August 2024 at roughly USD 100 million plus assumed liabilities. The deal was the first foreign acquisition of a US commercial shipyard under the FIRRMA regime and cleared CFIUS with mitigation conditions on technology transfer and workforce. Hanwha's stated plan is USD 5 billion over ten years to lift Philly's annual cadence from 1.5 to 4 hulls per year and to add LNG and offshore wind installation vessel capability.

HD Hyundai Heavy Industries, the largest commercial shipbuilder in the world by 2024 delivered tonnage, signed an MOU with HII in April 2024 covering naval auxiliary platforms, T-AKE follow on dry cargo ships, and modular construction methods transfer. The agreement does not include foreign control of HII assets. Mitsubishi Heavy Industries opened a separate dialogue with HII in late 2024 on icebreakers, where the United States operates two heavy icebreakers against a Coast Guard requirement of eight to nine. The Kelly and Andy Kim shipbuilder visa bill, introduced January 2025, would create a dedicated EB classification for skilled foreign shipyard workers.

Korean labor cost per delivered CGT runs roughly half the US figure with higher productivity. The transferable assets are not steel cutting. They are panel line automation, modular pre outfitting, design for production, and tier two supplier governance, capabilities that take a decade to build internally and five years through a structured partnership.

USTR Section 301 and the China yard share question #

USTR opened a Section 301 investigation in April 2024 into Chinese practices in the maritime, logistics, and shipbuilding sectors, on petition from five labor groups led by the United Steelworkers, IAM, Boilermakers, IBEW, and AFL-CIO Maritime Trades Department. The petition documented a Chinese commercial yard sector that grew from roughly 10 percent of global CGT in 2000 to roughly 50 percent by 2024, supported by direct subsidies, preferential lending through the Export-Import Bank of China, debt forgiveness, and state coordinated demand from COSCO Shipping.

USTR issued preliminary findings in February 2025 that Chinese shipbuilding practices were unreasonable and discriminatory, and proposed remedies including a port service fee on Chinese built vessels calling US ports, a fleet composition fee on operators with high Chinese built tonnage shares, and a phased preference for non Chinese built tonnage under Section 55305 cargo preference rules. Industry associations including the World Shipping Council warned that port call fees would translate to higher consumer prices. The final remedy package, expected by end of 2026, will set the operative tariff cost on imported transport services and condition the commercial economics of any US flag fleet expansion.

The strategic logic is symmetric to the SHIPS Act. Section 301 closes the demand side gap. SHIPS funding closes the supply side. Neither alone reverses the structural concentration of commercial shipbuilding in East Asia. Together, with Korean and Japanese capital inside US yards, they constitute the most coherent maritime industrial policy stack the United States has assembled since the 1936 Merchant Marine Act.

Workforce, schedule, and the 2026 to 2034 decision window #

The shipyard workforce gap is the binding human constraint. The BlueGreen Alliance and Shipbuilders Council of America 2024 report estimates the US sector requires roughly 100,000 additional skilled tradespeople by 2030 against a current direct employment baseline of approximately 110,000 across naval and commercial yards. Apprenticeship completion and trade school enrollment recovered modestly through 2024 and 2025, but the math does not close on domestic supply alone. The Kelly and Kim shipbuilder visa bill, EB-5 reforms, and bilateral mobility agreements with Korea, Japan, and the Philippines are the explicit and implicit responses.

For OEMs and primes, three operating implications follow. HII and General Dynamics need to formalize Korean and Japanese capability transfers at the program level, not just in framework agreements, because design for production methods and modular outfitting cycle times will determine whether SHIPS Act funding translates into delivered hulls or into overhead expansion. Commercial yard owners including Hanwha and any subsequent acquirer of Bollinger or VT Halter need to lock in tier two supplier consolidation and Navy auxiliary order pipelines. Federal procurers in MARAD, the Navy, the Coast Guard, and DOE need to convert SHIPS Act funding into multi year contracts that yards can finance against.

For allied governments in Seoul, Tokyo, and Manila, the question is whether US yard equity stakes and capability sharing accelerate or constrain their own trajectories. Korean yards face an aging workforce and rising domestic costs that make US capacity expansion strategically attractive if IP boundaries are managed. Japanese yards face declining order books from the 2000s peak and have an interest in extending relevance through US partnerships. The 2026 to 2034 window, defined by the SHIPS Act envelope, the AUKUS Pillar 1 transfer schedule, and the Section 301 remedy calendar, is when these decisions are made. Either the United States rebuilds commercial and naval shipbuilding to a credible second tier global position behind East Asia, or it institutionalizes managed dependence on allied yards for everything except the most sensitive submarine and carrier construction. The choice is being made now, in the contract structures and capital flows of 2026 and 2027.
