South Korea’s HD Hyundai and U.S. engineering and construction group Kiewit have agreed to form HD Kiewit Shipbuilding, a joint venture that plans to begin construction of a new advanced U.S. shipyard in 2027 and reach full-scale operations in 2029, with roughly 3,000 American jobs at capacity. The yard is intended to pursue commercial vessels, U.S. Navy logistics and support ships, and the fabrication of large ship blocks and modules for other American shipbuilders. Unlike Hanwha’s acquisition of the existing Philadelphia shipyard, HD Hyundai is proposing a new production facility designed around its own digital and automated shipbuilding system. The exact site, total capital cost and first vessel order have not yet been publicly announced. The project sits within the much larger U.S.-South Korean shipbuilding framework that calls for $150 billion of Korean investment in the U.S. shipbuilding sector, but that $150 billion is not the budget for this individual yard.
HD Hyundai + Kiewit · U.S. Shipbuilding
This Is Planned as a New Production System, Not Just Another Yard Upgrade
HD Hyundai intends to transfer shipbuilding production methods developed inside one of the world's largest shipbuilding groups into a newly configured American facility instead of retrofitting every process around an inherited yard layout.
Proposed Joint Venture

Four Revenue Paths Are Already Being Considered
Navy Logistics Ships
Auxiliary and support vessels offer a potential entry point into U.S. government shipbuilding.
Commercial Ships
Domestic commercial construction creates a route into Jones Act and U.S.-flag fleet renewal.
Blocks & Modules
Large prefabricated sections could be supplied to existing American shipyards rather than waiting for complete-ship orders.
Port Infrastructure
The partners also plan to explore adjacent maritime-infrastructure projects.
Already Confirmed
Joint venture agreement · new U.S. shipyard · 2027 construction target ·
2029 operating target · approximately 3,000 jobs · commercial and naval-support
opportunities · blocks and modules · smart-yard technology.
Still Open
Exact yard location · final acreage · capital investment · ownership split ·
dry-dock dimensions · annual ship capacity · first vessel type · first customer ·
construction contract value.
Can Korean Shipbuilding Economics Transfer to America?
Automation Helps. Production Architecture Matters More.
Korea's advantage is not one welding robot or one software package. It is the combination of mature design, serial production, enormous blocks, tightly synchronized suppliers, high yard utilization and production systems designed around repeatable flow.
HD Hyundai FOS 2030 Target
+30% Productivity
HD Hyundai also targets roughly 30% shorter lead times when its full
Future of Shipyard system is implemented. Those are corporate smart-yard
targets, not promised results for the new U.S. facility.
U.S. Commercial Cost Gap
~4× World Price
CRS uses roughly four times world-market prices as an illustrative starting point for U.S.-built commercial ships.
U.S. Navy Yard Position
Delivery Goals Missed
GAO says infrastructure, workforce and acquisition problems continue across major Navy programs.
Korean Industrial Scale
27% Global Completions
Korea represented about 27% of global CGT completions in 2024.
Korean Supply Base
Thousands of Suppliers
Dense domestic supplier networks allow parts and labor to move into Korean yards rapidly.

| Production Lever | Typical U.S. Constraint | HD Hyundai Method | Potential U.S. Benefit | Transfer Barrier | Metric to Watch at HD Kiewit |
|---|---|---|---|---|---|
| Digital Production One data backbone | Design, planning, supply and shop-floor information can live in disconnected systems, increasing rework and slowing changes. | FOS connects design, production planning, material flow, welding, piping and electrical information through digital twins and integrated models. | Earlier detection of production conflicts, less manual data transfer, better work sequencing and more predictable block completion. | Existing U.S. Navy systems, cybersecurity requirements, government configuration control and legacy supplier data may limit integration. | Rework hours, planning-cycle time, design-change incorporation time and percentage of production instructions generated digitally. |
| Mega-Block Construction Build large sections separately | Prime yards can become bottlenecks when too much fabrication, outfitting and final integration competes for the same footprint. | Korean yards extensively prefabricate and outfit large blocks before final erection, moving work into parallel production streams. | HD Kiewit could fabricate complete modules for both its own ships and existing U.S. yards, expanding capacity without duplicating every facility. | Transport dimensions, Navy certification, interfaces between yards and precision requirements become critical. | Percentage of outfitting completed before block erection, outsourced production hours and block-delivery schedule adherence. |
| Serial Production Repeat the same design | Small production runs and repeated redesign reduce learning-curve benefits. | Korean commercial yards favor multi-ship series with mature designs, bulk material buying and repeat production. | Commercial vessels and standardized Navy auxiliaries could achieve lower unit costs with each follow-on hull. | U.S. procurement can change requirements between hulls or fund ships irregularly, interrupting production rhythm. | Labor hours per hull, cost change from Hull 1 to Hull 2, schedule change across a vessel series and annual yard utilization. |
| Automation Robots supplement scarce trades | U.S. yards report persistent shortages of welders, pipefitters, machinists and experienced supervisors. | Robotic and mechanized welding, automated steel processing, digitally generated work packages and optimized material movement. | More output per skilled employee and less reliance on adding workers in exact proportion to production. | Automation still requires trained operators, maintenance technicians, welding qualification and stable production geometry. | Weld inches per labor hour, robot utilization, first-pass quality, training duration and employee turnover. |
| Supplier Density Parts close to the yard | U.S. shipbuilders depend on thinner and geographically dispersed supply chains, with some components having very few qualified sources. | Korean yards operate inside dense marine-equipment clusters with thousands of companies supplying engines, piping, electrical gear and outfitting. | A new U.S. yard could attract suppliers around it and standardize procurement across commercial and government programs. | A Korean supply ecosystem cannot simply be recreated in Texas or California by opening a shipyard. Localization takes years and sustained order volume. | Domestic-content percentage, supplier lead times, sole-source components and number of qualified local vendors. |
| Design Maturity Build after engineering stabilizes | GAO repeatedly identifies construction starting before designs are mature as a cause of U.S. naval cost and schedule problems. | High-volume commercial production depends on freezing designs and pushing manufacturing information to the yard before steel work advances. | Korean production methods could sharply reduce avoidable rework when paired with stable vessel requirements. | No manufacturing system can eliminate the cost of late government requirement changes, immature combat systems or incomplete engineering. | Design completion at construction start, engineering-change count, rework percentage and configuration changes after block fabrication. |

Best Initial Fit
Repetitive commercial ships, fleet oilers, logistics ships, sealift vessels
and standardized modules are closest to the production environment where
Korean serial-building methods have their strongest advantage.
Hardest Transfer
Nuclear submarines, aircraft carriers and highly customized surface combatants
have dense military systems, specialized steels, survivability requirements
and low production quantities that prevent a simple one-for-one transfer
of commercial Korean shipbuilding economics.

not forecasts for HD Kiewit Shipbuilding. Actual U.S. results will depend on design
maturity, wages, supplier localization, vessel type, domestic-content rules,
workforce experience, yard utilization, government requirements and the ability
to build repeated ships from stable designs.
