The Ships for America Act: Challenges and Opportunities for South Korea

The Ships for America Act, introduced in December 2024, signifies a transformative effort by the United States to reclaim its long-diminished shipbuilding industry. The act represents an ambitious attempt to rebuild the capacity of U.S. shipyards, expand the nation’s maritime workforce, and strengthen national security by reducing reliance on foreign-built ships. While the act’s immediate focus lies in domestic revitalization, its broader implications resonate across the global shipbuilding industry, particularly for South Korea. As a global leader in shipbuilding, South Korea faces the dual challenge of adapting to the competitive pressures stemming from the act while exploring opportunities for collaboration with the United States.

The United States has long struggled with a declining shipbuilding industry, characterized by aging infrastructure, reduced competitiveness, and a significant loss of skilled labor. The SHIPS Act seeks to address these vulnerabilities through tax incentives, workforce development programs, and strategic investments in modernization. Specifically, the act introduces a 25 percent tax credit for shipyard upgrades and a 33 percent credit for vessel construction and retrofitting, providing substantial financial support to attract investment in U.S. shipyards. Additionally, the establishment of a U.S. Center for Maritime Innovation signals the country’s intent to foster advancements in ship design, green technologies, and autonomous systems. These measures collectively aim to position the United States as a competitive player in global shipbuilding markets while simultaneously securing its supply chains and enhancing logistical capacity for military operations.

For South Korea, the SHIPS Act represents a critical moment in its maritime trajectory. South Korea has long dominated the global shipbuilding industry, excelling in high-value vessels such as LNG carriers, ultra-large crude oil tankers, and eco-friendly ships powered by hydrogen and ammonia. Companies like Hyundai Heavy Industries, Samsung Heavy Industries, and Daewoo Shipbuilding & Marine Engineering have become synonymous with innovation and efficiency, capturing significant shares of the global market. However, the competitive landscape is shifting. In 2023, South Korea’s share of global shipbuilding orders dropped to 24 percent, an eight-year low, while China captured 59 percent of orders through aggressive pricing strategies and state subsidies. The SHIPS Act introduces another dimension to this evolving landscape, as the United States seeks to re-establish itself as a maritime powerhouse.

The competitive pressure from the SHIPS Act is particularly evident in its protectionist provisions. By mandating that government-funded cargoes be transported on U.S.-flagged vessels, the act effectively limits opportunities for foreign-built ships, including those from South Korea, to participate in American logistics networks. Furthermore, the act’s focus on localizing production incentivizes South Korean companies to establish operations within the United States if they wish to maintain access to this lucrative market. This structural shift challenges South Korea’s traditional approach to supplying advanced ships globally and forces its shipbuilders to adapt their strategies in response to evolving market conditions.

Despite these challenges, the SHIPS Act also creates significant opportunities for collaboration between South Korea and the United States. The U.S. shipbuilding sector, while ambitious in its goals, lacks the capacity and expertise to quickly meet the act’s targets, particularly in high-value and technologically complex vessels. This gap presents a pathway for South Korea to position itself as a strategic partner. Its leadership in green technologies, such as ammonia-powered ships and LNG dual-fuel propulsion systems, aligns closely with the sustainability goals outlined in the SHIPS Act. By exporting these technologies or entering joint ventures with U.S. shipyards, South Korean firms can contribute to the act’s success while securing their influence in a key market.

However, such collaborations are not without risks. The possibility of technology transfer through partnerships poses a significant threat to South Korea’s competitive advantage. Proprietary innovations in automated shipbuilding processes and green propulsion systems, which form the backbone of South Korea’s industry, could be at risk of appropriation in collaborative projects. Ensuring robust intellectual property protections and negotiating clear terms in joint ventures will be essential for South Korea to mitigate these risks while engaging with the U.S. shipbuilding ecosystem.

The geopolitical context of the SHIPS Act further complicates South Korea’s position. The act is part of a broader U.S. strategy to counterbalance China’s maritime dominance, particularly in the Indo-Pacific region. A robust U.S.-flagged fleet and modernized shipbuilding capacity are critical to maintaining supply chain resilience and ensuring military mobility in this strategic theater. For South Korea, as a close U.S. ally, this dynamic creates both opportunities for deeper security collaboration and potential tensions with China, which remains South Korea’s largest trading partner. Navigating this delicate balance will require South Korea to carefully align its economic and strategic interests.

To adapt to the challenges posed by the SHIPS Act, South Korea must adopt a proactive and diversified strategy. Strengthening its leadership in green shipbuilding technologies is paramount. Continued investment in research and development will ensure that South Korea remains at the forefront of innovation, making its expertise indispensable even as competitors emerge. Additionally, South Korea should consider strategic investments in U.S.-based shipyards, enabling its companies to comply with domestic production requirements while influencing the development of the American shipbuilding sector. Expanding its global market reach beyond traditional strongholds will also be crucial. By diversifying into emerging markets in Southeast Asia, Europe, and the Middle East, South Korea can mitigate risks associated with U.S. protectionist policies.

The Ships for America Act represents a watershed moment not only for the United States but also for the global shipbuilding industry. For South Korea, it encapsulates the dual realities of competition and collaboration in an increasingly interconnected world. While the act challenges South Korea’s market dominance, it also opens new pathways for partnership and innovation. By leveraging its strengths, protecting its technological edge, and navigating the geopolitical landscape with agility, South Korea can turn these challenges into opportunities for sustained global leadership. As the maritime sector continues to evolve, the decisions made in response to the SHIPS Act will shape the future of global shipbuilding for decades to come.
