HD Hyundai and Kiewit form U.S. shipyard venture for 2029

HD Hyundai USA and Kiewit Maritime agreed on Oct. 22 to establish a joint venture to build an advanced shipyard in the United States, targeting naval auxiliary and commercial vessels.

The proposed entity, named HD Kiewit Shipbuilding LLC, will develop a purpose-built yard on an existing industrial property. Construction is scheduled to start in 2027, with full-scale operations planned for 2029.

The companies did not disclose the dollar value of the capital investment, the equity split or the specific site in their joint statement. Neither HD Hyundai nor holding company HD Korea Shipbuilding & Offshore Engineering had filed a transaction disclosure with the Korea Exchange as of Oct. 23.

The venture marks the first American deployment of HD Hyundai's smart shipyard system. That operating model uses automated block transport, digital twin design tracking and robotic plate welding to reduce manual shipyard labor.

Initial production will center on commercial cargo hulls, naval auxiliary craft and intermediate structural blocks for domestic shipbuilders. Those sub-assemblies feed prime American defense yards facing delivery backlogs on naval logistics hulls.

The project creates a domestic manufacturing channel that conforms to the Jones Act. The 1920 federal statute requires vessels moving cargo between American ports to be built in domestic yards and crewed by American citizens.

Foreign shipbuilders cannot deliver completed commercial ships directly into the American domestic trade. By assembling blocks and finished hulls inside an American yard through a local entity, HD Hyundai enters that protected market without breaching statutory build tests.

The initiative also aligns with United States Navy procurement needs for auxiliary support vessels. Auxiliary hulls include oilers, dry cargo transports and salvage ships operated by Military Sealift Command, which do not carry the combat systems of frontline surface combatants.

Kiewit Maritime brings the domestic fabrication infrastructure to the venture. The company is an affiliate of Kiewit Offshore Services, which operates a 400-acre heavy marine construction yard in Ingleside, Texas.

That Gulf Coast facility carries large heavy-lift cranes and deepwater bulkhead access used for offshore oil platforms. The site provides an existing industrial base, eliminating the need to permit a greenfield coastal shipyard from scratch.

HD Hyundai brings commercial vessel engineering and procurement integration. The South Korean shipbuilder delivered 182 merchant vessels in 2025 across its three Korean yards and operates the world's largest commercial shipyard in Ulsan.

The agreement signed on Oct. 22 formalizes talks that began earlier this year. The two companies signed an initial strategic cooperation agreement at Kiewit's Ingleside headquarters on July 16, agreeing to assess block and module assembly.

HD Hyundai has pursued parallel ties with American defense shipbuilders. HD Hyundai Heavy Industries signed a separate cooperation pact earlier this year with Huntington Ingalls Industries, which builds all American nuclear-powered aircraft carriers and shares submarine construction with General Dynamics Electric Boat.

That arrangement with Huntington Ingalls focuses on engineering support for naval auxiliaries. The new joint yard with Kiewit provides the physical steel-fabrication capacity needed to convert that engineering work into delivered blocks.

The venture's output will also address chronic capacity shortages at American yards. Commercial orders in the United States have fallen below 1% of global shipbuilding output, leaving domestic defense builders competing for steelworkers and dry docks.

Fabricating modular ship sections off-site allows prime defense contractors to shorten dry dock occupancy times. A modular block yard can weld and outfit double-bottom blocks before moving them into final assembly basins.

Choi Han-nae, corporate planning head at HD Korea Shipbuilding & Offshore Engineering, attended the signing alongside Andrew Hong, chief executive of HD Hyundai USA. Chad Johnson, president of Kiewit Maritime, represented the American partner.

The joint venture allows South Korea's maritime supply chain to supply propulsion components and deck machinery to American hulls. Korean ship equipment makers book about 40% of their revenue from equipment packages tied to HD Hyundai hulls.

Those components must still meet federal procurement domestic content rules when applied to Navy contracts. Commercial Jones Act vessels face fewer domestic machinery restrictions than combatant programs, provided the hull steel is fully assembled onshore.

The partners must complete structural formation of the operating company before the 2027 groundbreaking date. The final site selection, regulatory review filings and initial block production schedules will follow during the 2027 calendar year.

The release left several key commercial parameters unresolved. The companies have not published the square footage of the planned yard, their respective ownership shares or whether they intend to construct a dedicated graving dock.
