  The U.S. shipbuilding industry is failing to keep pace with China's rapid naval expansion, posing a serious threat to American sea power. The article argues that incremental improvements are insufficient and calls for a fundamental "shipbuilding revolution." This revolution must include adopting commercial best practices like modular construction and serial production, streamlining regulatory hurdles, investing in workforce development, and fostering a more collaborative relationship between the Navy and shipbuilders. Ultimately, the author advocates for prioritizing quantity and speed of production over exquisite, highly customized designs to ensure the U.S. Navy maintains its competitive edge.

  The article "The U.S. Needs a Shipbuilding Revolution," published in the February 2025 edition of Proceedings, a journal of the U.S. Naval Institute, passionately argues that the current state of American shipbuilding is inadequate to meet the looming challenges of a rapidly evolving geopolitical landscape and an increasingly assertive China. The authors, Bryan Clark, Dan Patt, and Mark Rosen, meticulously detail the multifaceted nature of the problem, highlighting a complex interplay of factors hindering the nation's ability to produce and maintain a fleet capable of projecting power and safeguarding national interests.

  Central to their argument is the assertion that the current paradigm of bespoke, exquisitely engineered warships, while resulting in technologically advanced vessels, comes at the unacceptable cost of protracted build times, exorbitant expenses, and limited production capacity. This approach, the authors contend, renders the United States vulnerable to numerically superior adversaries who can field larger fleets more rapidly. They posit that this vulnerability is further exacerbated by the extended periods required for maintenance and repair, leading to a significant portion of the fleet being unavailable for operational deployment at any given time.

  The authors propose a radical shift in philosophy, advocating for a "shipbuilding revolution" centered around the concept of modularity and distributed maritime operations. They envision a future fleet composed of a greater number of smaller, more adaptable vessels, constructed using standardized modules that can be readily swapped and upgraded. This modular approach, they argue, would enable faster construction, simplified maintenance, and increased flexibility in adapting to evolving threats. Furthermore, it would facilitate distributed operations, dispersing naval power across a wider area and making it more resilient to enemy attack.

  This transition, the authors acknowledge, would necessitate a substantial overhaul of the current shipbuilding infrastructure, requiring investment in new facilities, technologies, and workforce training. They emphasize the importance of fostering collaboration between the Navy, private shipyards, and research institutions to accelerate the development and implementation of these transformative changes. Furthermore, they stress the need for a cultural shift within the Navy, moving away from the traditional emphasis on large, complex platforms towards a more agile and adaptable force structure.

  The article concludes with a call to action, urging policymakers and naval leadership to embrace this paradigm shift and prioritize the necessary investments to revitalize the American shipbuilding industry. The authors warn that failure to adapt to the changing geopolitical realities will leave the United States at a strategic disadvantage, jeopardizing its ability to maintain maritime dominance and protect its interests in the coming decades. They paint a vivid picture of the potential consequences of inaction, emphasizing the urgency of embarking on this shipbuilding revolution to ensure the continued strength and security of the nation.

  HN commenters largely agree with the article's premise that US shipbuilding needs reform. Several highlighted the inefficiency and cost overruns endemic in current practices, comparing them unfavorably to other industries and even other countries' shipbuilding. Some suggested specific solutions, including focusing on simpler, more easily mass-produced designs, leveraging commercial shipbuilding techniques, and reforming the acquisition process. Others pointed to bureaucratic hurdles and regulatory capture as significant obstacles to change. A few questioned the underlying strategic assumptions driving naval procurement, arguing for a reassessment of overall naval strategy before embarking on a shipbuilding revolution. Several commenters with apparent domain expertise provided insightful anecdotes and details supporting these points.

  The Hacker News post titled "The U.S. needs a shipbuilding revolution" linking to a USNI Proceedings article has a moderate number of comments discussing various aspects of the shipbuilding industry and the article's claims.

  Several commenters focus on the issues of cost and efficiency within the current US shipbuilding system. One commenter argues that the real problem isn't a lack of shipyard capacity, but rather a procurement system that prioritizes bespoke designs and gold-plated requirements, leading to exorbitant costs and long lead times. This commenter suggests that focusing on simpler, more modular designs and building ships in larger series would drastically reduce costs and improve production speed. Another commenter echoes this sentiment, pointing out the success of other countries, like South Korea, which produce ships faster and cheaper by utilizing more standardized designs and efficient production methods. They highlight the contrast with the US approach, which often involves extensive customization and modifications throughout the construction process, leading to delays and cost overruns.

  Another line of discussion centers around the workforce and skills gap in the shipbuilding industry. One commenter observes that finding and retaining skilled labor is a major challenge, especially welders, and this shortage contributes to the slow pace of production. They suggest that investing in training and apprenticeship programs is crucial to addressing this issue.

  Some commenters express skepticism about the feasibility of a rapid shipbuilding revolution, citing the complex regulatory environment and the entrenched interests of existing shipyards. One commenter argues that the US Navy's preference for complex, highly capable ships is driven by strategic considerations and that simply building simpler ships might not be a viable solution. They suggest that a more realistic approach would involve incremental improvements to the existing system rather than a radical overhaul.

  Finally, several commenters discuss the strategic implications of the shipbuilding challenges. They note the growing naval power of China and argue that the US needs to find a way to build ships more quickly and efficiently to maintain its maritime superiority. One commenter points out that even if the US manages to increase its shipbuilding capacity, it may still struggle to keep pace with China's rapid naval expansion.

  In summary, the comments on the Hacker News post offer a range of perspectives on the challenges facing the US shipbuilding industry. The most compelling comments highlight the issues of cost, efficiency, workforce shortages, and the strategic implications of the slow pace of shipbuilding. While some commenters advocate for a radical overhaul of the system, others suggest a more incremental approach. The discussion reflects a general concern about the US Navy's ability to maintain its maritime advantage in the face of growing competition.
