K-Shipbuilding and the Ambitious “Golden Fleet” Vision: A Reality Check from Washington
A recent announcement by U.S. President Donald Trump, dubbed the “Golden Fleet” plan, has ignited considerable speculation, particularly within South Korea’s thriving shipbuilding sector. The proposal, which centers on the revival of a “Trump-class warship” and designates South Korea’s Hanwha Ocean as a partner for frigate construction, has led to optimistic forecasts of “K-Shipbuilding” revitalizing the U.S. Navy. However, a closer examination of the situation from Washington reveals a more complex and challenging landscape, marked by significant systemic barriers and differing perspectives.
While the sentiment in Seoul buzzes with the potential for a shipbuilding renaissance, experts in Washington express a more tempered view. Six U.S. Navy and defense specialists, when consulted, unanimously acknowledged the “excellent shipbuilding capabilities” of South Korea. Nevertheless, they also emphasized that the “barriers and limitations of the U.S. system are much higher and more robust than South Korea might think.” This divergence in perspective highlights the crucial gap between political rhetoric and the practical realities of defense procurement and industrial policy within the United States.
To understand the feasibility of Hanwha’s ambitions and Trump’s “Golden Fleet” vision, a deep dive into four key issues is essential, as analyzed by Washington’s shipbuilding experts.
1. Frigate Construction at Philly Shipyard: Navigating American Industrial Hurdles
A central pillar of Trump’s “Golden Fleet” plan involves Philly Shipyard in Pennsylvania, now under the ownership of Hanwha Ocean, taking on the mass production of frigates. However, significant questions arise given the shipyard’s historical focus on commercial vessels and its lack of prior military shipbuilding experience. Experts point to two primary obstacles: the persistent “shortage of skilled workers” and the stringent “Buy American” regulations.
Naval expert Chris Cavas, with three decades of experience observing U.S. shipyards, articulated the complexities of military shipbuilding. “Military shipbuilding requires countless parts,” he explained. “Radars, sensors, weapons, and engines are all made by different companies.” Cavas highlighted the critical issue of supply chain management, stating, “Shipyards cannot control the delivery of these equipment. Dealing with the U.S. supply chain, which has worsened since the pandemic, is a massive problem that Hanwha will face in the U.S.”
The “Buy American Act” further complicates matters, mandating that 60-75% of components in federal procurement must be U.S.-made. Cavas noted the political pressure inherent in this legislation: “If parts can be better sourced from Japan, South Korea, or Germany, lawmakers will say, ‘Well, I want my district’s company in Cleveland to supply them.’ As you know, shipyards have no authority to refuse this.” This contrasts sharply with South Korea’s shipbuilding prowess, which relies on cost-effective, high-quality components sourced domestically. For U.S. Navy warships, this would necessitate the use of more expensive, slow-to-deliver U.S.-made materials and equipment, significantly impacting cost and timelines. Cavas also critically dismissed Trump’s “Golden Fleet” plan as “a waste of time, money, and everything,” labeling it an “amateurish idea that will never happen,” a sentiment echoed by many who view the concept as an outdated Cold War strategy ill-suited to modern naval warfare.
Eric Labs, a senior analyst for naval forces and weapons at the U.S. Congressional Budget Office (CBO), provided a more quantitative perspective. He suggested that while Hanwha’s management expertise might offer some improvements, the “high wage structure, overhead costs, and expenses of domestically procured parts” in the U.S. remain formidable challenges. Citing OECD data, Labs pointed out that South Korea’s wage levels are approximately 60% of those in the U.S., with labor costs constituting a significant 40% of shipbuilding expenses. Hiring expensive U.S. workers presents a substantial financial burden, making it difficult to achieve significant cost reductions.
Furthermore, Labs questioned Philly Shipyard’s readiness for frigate construction, asking, “whether the yard is familiar with frigate designs and has the necessary equipment to start construction quickly. It’s also questionable whether they have enough skilled workers and diverse technical experts required for military shipbuilding, not just commercial vessels.”
Cynthia Cook, a senior fellow at the Center for Strategic and International Studies (CSIS), underscored the limitations of the U.S. supply chain. She argued that Hanwha’s supply chain management expertise, honed in South Korea’s unique environment, would be “difficult to replicate in Philadelphia.” Cook predicted that “discovering suppliers and building a strong supply base in the U.S.—where the supply chain has collapsed—will be a huge challenge.” She concluded, “There’s no magic; only hard work will be needed.”
2. The Nuclear Submarine Conundrum: A Political and Security Minefield
Hanwha’s declared interest in venturing into the U.S. nuclear submarine business has been met with significant skepticism, not due to technological limitations, but rather due to profound political and security considerations.
James Holmes, a distinguished professor of maritime strategy at the U.S. Naval War College, highlighted the stringent security clearance processes. “Even U.S. citizens struggle to obtain security clearances for nuclear-related work,” he noted, referencing historical incidents like Toshiba’s leak of submarine noise-reduction technology to the Soviet Navy during the Cold War. Holmes emphasized that “export controls have become a key part of U.S. foreign policy, and the defense community has deep trauma over espionage and illegal technology transfers.” He believes that even if South Korea were to pursue its own nuclear submarine program, it would be highly improbable for Philly Shipyard to be involved. “It’s very hard to imagine Philly Shipyard building nuclear-powered submarines for the South Korean Navy. The yard has no prior experience with nuclear propulsion work. Considering both technical and political reasons, if South Korea builds nuclear submarines, it will likely happen in Korea.”
Cavas concurred, describing nuclear submarines as a “sacred concern” of U.S. security. While acknowledging the technical possibility, he stressed the overwhelming “political and security reasons why it won’t happen.” He elaborated that beyond nuclear propulsion, the intricate construction of submarine hulls, including steel bending and welding, requires the highest security clearances, with many of these technologies “extremely tightly guarded.” Cavas revealed that even with close allies like the UK, certain technologies are not shared.
The primary gatekeeper for U.S. nuclear submarine technology is “NAVSEA 08” (the Naval Sea Systems Command’s Nuclear-Powered Ship Division). This entity strictly enforces the “NOFORN” (No Foreign Nationals) principle, restricting access even to allied nations. Its authority over nuclear propulsion and combat systems technology is absolute, potentially preventing South Korean engineers at a U.S.-based, Korean-owned shipyard from accessing critical core technologies.
Colin Grabow, deputy director of the Cato Institute and an expert on U.S. maritime laws, pointed to a recent example involving Philly Shipyard’s order for two LNG carriers. “The two LNG carriers ordered by Philly Shipyard last year will mostly be built in South Korea,” he observed. “This suggests Hanwha doesn’t believe Philly Shipyard currently has the capability to build LNG carriers. How can a shipyard struggling to build LNG carriers construct frigates or nuclear submarines in the near future?” Grabow noted that while LNG carriers are technologically advanced commercial vessels, they are still significantly less complex than nuclear submarines. Philly Shipyard’s plan to construct core blocks in South Korea for these LNG carriers further underscores its current limitations, as it has historically built less complex vessels like container ships and oil tankers.
3. Overseas Construction of U.S. Warships: Legal and Policy Barriers
The possibility of constructing U.S. warships overseas, specifically in South Korea, is largely prohibited by U.S. federal law, including the Burns-Tollefson Act (10 U.S.C. § 8679).
James Kim, director of the Korea Program at the Stimson Center, explained that the U.S. Navy currently only permits limited maintenance, repair, and overhaul (MRO) of combat ships in select overseas locations like Japan and Singapore, where U.S. naval bases are situated. “Currently, even MRO for combat ships is not permitted in South Korea,” Kim stated. “Building warships there is not an easy short-term solution.” However, he acknowledged Trump’s unpredictability, suggesting that “what was previously impossible could become possible overnight.”
Holmes reiterated that the location of construction is a major hurdle, stating, “U.S. laws and policies make it extremely difficult to directly purchase warships from Hanwha Ocean, HD Hyundai Heavy Industries, or even Japanese or European companies.” Cavas was more definitive, asserting, “Under Trump’s term, U.S. warships won’t be built in South Korea. I don’t think such legislation will pass Congress.”
4. The Shadow of the November Midterm Elections
The upcoming November midterm elections are seen by many experts as a critical juncture that could significantly influence the fate of the “Golden Fleet” plan.
Cavas explained that a Republican loss of control in both the House and Senate could empower Congress to halt the project by withholding funding. “Trump can still sign what he wants, but executive orders alone can’t build a fleet.”
Kim added that there is no concrete timeline for the “Golden Fleet” implementation, and even within the Republican party, other priorities exist. He questioned whether pushing this initiative before the midterms would be strategically sound. Despite these immediate uncertainties, Kim maintained that “South Korea remains the most likely country to succeed in shipbuilding cooperation and investment in the U.S.” He concluded that while immediate success is challenging, “it’s not impossible in 10 or 20 years. How to overcome structural constraints like labor issues will be the challenge moving forward.”
