Samsung Heavy Enters US Naval Shipbuilding Under $150B MASGA Program

South Korea's shipbuilding giants have spent decades dominating the commercial orderbook. Now one of them is crossing into American naval territory.

Samsung Heavy Industries confirmed this week that it has joined its first US Navy design project, partnering with General Dynamics NASSCO on the Next Generation Logistics Support Ship (NGLS). The collaboration --- funded through a $3.9 million contract awarded to NASSCO --- represents the first concrete deliverable under the broader Make American Shipbuilding Great Again initiative, a $150 billion investment framework launched last year to revitalize American maritime industrial capacity with allied support.

What the NGLS Program Needs

The NGLS is designed for the US Navy's "Distributed Ocean Operations" strategy, which envisions a more dispersed fleet posture requiring smaller, highly maneuverable logistics vessels capable of refueling, rearming, and resupplying combat ships and Marine units at sea. The Navy plans to build up to 13 of these ships, making the program a significant long-term procurement commitment.

Samsung's contribution centers on high-efficiency hull design, drawing on the company's 400-meter commercial test tank at its Daedeok Research Center --- the largest of its kind globally. The company will also leverage a newly established research hub at San Diego State University, created in March as part of a broader Korean-American maritime R&D partnership.

DSEC, a South Korean defense engineering firm, rounds out the design team alongside Samsung and NASSCO. The contract runs through March 2027.

Why Korea, Why Now

The MASGA framework exists because of a blunt industrial reality: the United States builds fewer than five large commercial vessels per year, while South Korea delivers hundreds. American shipyards have the workforce pipeline and defense integration but lack modern commercial shipbuilding throughput. Korean yards have the production technology and efficiency but need access to the US defense market to diversify beyond commercial cycles.

The arrangement is explicitly transactional. South Korean shipbuilders gain a foothold in US naval procurement --- historically one of the most protected markets in global defense --- while the US Navy gets access to design expertise and production methodologies that its own industrial base cannot currently provide at scale.

For Samsung Heavy, the NGLS project is a proof-of-concept. If the hull design work demonstrates value, the company positions itself for deeper involvement as the NGLS program moves from design to construction --- and potentially for other MASGA-adjacent programs including LNG carrier builds for US energy export terminals.

Industry Implications

The broader Korean shipbuilding sector views MASGA as a growth catalyst. Analysts at Hellenic Shipping News have noted that US LNG and MASGA projects are expected to fuel Korean shipbuilding growth throughout 2026, diversifying revenue streams that have been heavily dependent on container and LNG newbuild cycles.

HD Hyundai, the world's largest shipbuilder, has also signaled interest in MASGA participation, though it has not yet announced a specific contract. Hanwha Ocean, the third major Korean yard, is positioning for auxiliary and support vessel work.

For the US maritime industrial base, MASGA represents a strategic bet that allied partnerships can close capability gaps faster than domestic rebuilding alone. MARAD has complemented the initiative by expanding funding for its Small Shipyard Grant Program in 2026, targeting domestic yard modernization alongside the allied design partnerships.

The Larger Picture

The Samsung-NASSCO collaboration is modest in dollar terms --- $3.9 million is a rounding error in naval procurement. But as a signal, it carries weight. It demonstrates that the MASGA framework can produce actual work products, not just memoranda of understanding. And it establishes a template for how allied shipbuilding expertise might flow into US naval programs without triggering the political sensitivities that accompany direct foreign construction of American warships.

The test will be whether design collaboration scales into production collaboration. For now, Samsung is drawing hull lines in San Diego. The 13-ship NGLS program will determine whether Korean technology eventually shapes American keels.
