The National Security Risk of America’s Shipbuilding Collapse: They Might as well Not have it at All!

The numbers are not a rounding error. They are a strategic verdict.

China builds roughly 50–60% of the world's commercial ships by tonnage in a given year. The United States builds a fraction of one percent, often cited in the 0.04–0.2% range, or fewer than five large oceangoing commercial vessels annually in recent years. Office of Naval Intelligence assessments have long put Chinese shipbuilding capacity at roughly 200+ times America's. In 2024–2025 alone, Chinese yards delivered more than twice the naval combatant tonnage of U.S. yards (about 636,000 tons versus 270,000), according to the Euronaval World Defense Shipbuilding report. The People's Liberation Army Navy now fields more hulls than the U.S. Navy (projections and counts in the mid-to-high 300s versus the low-to-mid 290s), and the gap in production tempo continues to widen.

At that disparity, America's remaining shipbuilding capacity is not a modest disadvantage. It is close to strategically irrelevant for the scenarios that matter most. In a prolonged high-intensity conflict, particularly over Taiwan or in the Western Pacific, the ability to replace losses, repair battle damage, surge logistics, and sustain a fleet over months or years is decisive. Peacetime hull counts and exquisite individual platforms matter less once attrition begins. On those metrics, the current U.S. industrial base provides so little meaningful resilience that, for pure national-security purposes in a peer war, one could argue they might as well not have commercial and large-scale naval shipbuilding capacity at all. The illusion of having it creates false confidence while the real constraints (delays, costs, workforce, and zero surge) remain.

China's advantage is not merely volume. It is structure. Major Chinese shipyards are dual-use by design under Beijing's military-civil fusion strategy. Commercial container ships, tankers, and bulk carriers are built alongside warships, submarines, and auxiliaries on shared infrastructure, dry docks, steel supply, and skilled labor. CSSC and its subsidiaries dominate both the commercial market and PLAN construction. Foreign commercial orders help keep the yards busy, subsidised, and technically current; the same capacity can be redirected toward military output with relatively little friction. Analyses from CSIS and others have documented how foreign (including Western) customers have effectively helped underwrite an industrial base that simultaneously expands the PLAN.

The United States has no equivalent. Its large naval yards are essentially specialised defense contractors with limited or no commercial work. Commercial shipbuilding has nearly vanished. When maintenance backlogs grow, submarines accumulating thousands of "active idle" days waiting for yard space, surface ships delayed for years, there is no commercial ecosystem to absorb overflow or provide surge workers and facilities. A single Chinese yard complex can exceed the total capacity of the entire U.S. naval shipbuilding base.

Even the ships the United States does build arrive late and over budget. Destroyers and submarines that once took five to six years now routinely take nine to ten or more. Carrier construction timelines have lengthened. Multiple major programs (Columbia-class SSBNs, Virginia-class SSNs, Ford-class carriers, earlier frigate efforts) have faced multi-year slips and cost growth. The Government Accountability Office has repeatedly noted that, despite roughly doubling the shipbuilding budget in real terms over two decades, the Navy's fleet size has not grown as planned. Throughput remains low; the industrial base cannot reliably deliver the numbers required to reach statutory or Navy force goals, let alone replace combat losses.

Workforce shortages, supplier fragility (many single-source items), aging facilities, and an acquisition system optimised for exquisite performance rather than predictable volume all compound the problem. Maintenance capacity is so constrained that ships sit unavailable for extended periods. Sealift, the merchant shipping needed to move ammunition, fuel, and equipment in a crisis, is chronically inadequate without heavy reliance on foreign-flagged or foreign-built vessels, many of them Chinese. Crew shortages have already forced the lay-up of support ships.

These are not temporary hiccups. They are the product of decades of underinvestment, boom-bust cycles, protectionism that insulated yards from commercial competition (while China, Korea, and Japan competed and scaled), and a strategic culture that treated maritime industrial power as secondary once the Cold War ended.

In a Taiwan contingency or any extended Pacific fight, China could lose ships and replace or repair them at a tempo the United States cannot match. Logistics chains dependent on non-U.S. shipping become points of failure or coercion. Deterrence rests partly on the credible ability to sustain operations; the current capacity gap undermines that credibility. Efforts to partner with Korean or Japanese yards, or limited foreign construction of auxiliaries under recent policy, are pragmatic stopgaps that acknowledge the domestic shortfall, but they introduce their own technology-protection and dependency risks and do not instantly recreate a resilient U.S. industrial base.

The Trump administration's 2025 executive order on restoring maritime dominance, the SHIPS Act proposals, and related initiatives recognize the problem and aim at incentives, workforce, and allied investment. Those are necessary. But the scale of the deficit means incremental funding or modest reforms will not close a 200-to-1 capacity gap or reverse the commercial disappearance in time for near-term contingencies. Without a genuine commercial market that keeps yards and suppliers at scale year-round, naval shipbuilding remains a high-cost, low-volume activity vulnerable to the next budget cycle or workforce retirement wave.

A shipbuilding sector that produces a negligible share of global commercial tonnage, cannot surge, delivers warships years late, and leaves the Navy dependent on foreign capacity for both construction support and sealift is not providing the national-security insurance its advocates claim. It is a residual capability that consumes resources while creating the appearance of readiness. In pure strategic terms, especially against a peer that treats commercial and military shipbuilding as one fused system, the present arrangement is close to the functional equivalent of having no meaningful shipbuilding capacity at all for wartime regeneration and sustainment.

Reversing this requires more than rhetoric or additional Navy contracts. It demands a commercial industrial base large enough to matter, allied production arrangements that actually transfer capacity and know-how, ruthless prioritisation of throughput over perfection, and acceptance that protectionist rules alone have not preserved the industry. Until that changes, the national-security risk is not merely that America builds fewer ships. It is that the capacity it still possesses is too small, too slow, and too brittle to alter outcomes when it is needed most.

As a friend said who worked in the area said about this: "we are not a serious country." Shipbuilding in Australia is even worse than the US.
