A Shipbuilding Gap Is Reshaping Naval Competition

The most consequential fact in modern naval strategy has nothing to do with missiles or radar — it is a spreadsheet number: deadweight tonnage. China’s shipyards now produce more than half the world’s commercial vessels, and that same industrial base, welders, steel mills, cranes, and all, builds the People’s Liberation Army Navy’s warships. The United States never rebuilt an equivalent civilian shipbuilding sector after the Cold War, and the gap between the two navies’ construction tempo has become the defining asymmetry of great-power competition at sea.

Key Points

China’s shipyards produced 53.69 million deadweight tonnes in 2025, 56.1 percent of global output, and that share climbed further in early 2026.
The PLA Navy commissioned more than 18 warships in 2025, including the aircraft carrier Fujian, seven Type 052D destroyers, and multiple frigates and nuclear submarines.
China’s commercial and naval shipbuilding share the same yards, giving Beijing a dual-use industrial advantage the U.S. cannot currently replicate.
American naval programs — Virginia-class submarines, Columbia-class boats, Arleigh Burke destroyers — are running years behind schedule and billions over budget.
Washington is turning to South Korea and Japan, not domestic capacity alone, to close the gap, a strategy with its own limits and timelines measured in decades.

The Numbers Behind the Headline

China’s Ministry of Industry and Information Technology reported that the country’s shipyards completed 53.69 million deadweight tonnes of shipping in 2025, an 11.4 percent increase over the prior year and 56.1 percent of everything built on Earth. New orders reached 107.82 million DWT, and the order backlog swelled to 274.42 million DWT — a record. By the first half of 2026, the trend had accelerated rather than plateaued: completions rose 51.2 percent year-on-year and China’s share of new global orders touched 82.3 percent, according to industry tracking data. These are not military figures. They are commercial tonnage statistics. But that is precisely the point — the same welders, the same dry docks, the same steel supply chains that produce container ships and LNG carriers are the ones the PLA Navy draws on for destroyers and submarines.

South Korea’s shipbuilding sector, still the world’s second-largest, produces roughly a quarter of global tonnage. The United States, by comparison, builds a fraction of one percent — commercial output measured in single-digit ships annually rather than hundreds. That imbalance did not appear overnight; it is the product of a four-decade divergence in industrial policy that began when American commercial shipbuilding collapsed in the 1980s after federal subsidies were withdrawn and Japanese, then Korean, then Chinese yards undercut U.S. costs on price and turnaround time.

From Aircraft Carriers to Attack Submarines: What Actually Launched

The abstractions become concrete in the hulls themselves. In 2025 the PLA Navy commissioned the aircraft carrier Fujian, an 80,000-tonne, electromagnetic-catapult-equipped vessel formally entered into service on November 5 at Sanya Naval Base with Xi Jinping presiding, alongside a Type 075 amphibious assault ship, a Type 055 large destroyer, seven Type 052D destroyers, and six frigates split between the Type 054A and the newer, all-electric Type 054B class. Two Type 093B nuclear-powered guided-missile attack submarines also entered service, each carrying 24 vertical-launch cells and built with quieter pump-jet propulsion that Western analysts assess as approaching the acoustic signature of improved U.S. Los Angeles-class boats. China currently operates roughly 68 submarines, twelve of them nuclear-powered — a fleet size comparable to the U.S. Navy’s own submarine force. Precise submarine production numbers remain somewhat inferential because Beijing maintains deliberate secrecy around that program, one of the few genuine caveats in an otherwise well-documented buildup.

How Beijing Built This Machine

The mechanism is dual-use industrial policy, pursued patiently over roughly three decades. China State Shipbuilding Corporation, formed through a 2023 merger of the country’s two largest state shipbuilders, now controls more than 140 yards and research institutes, with a commercial backlog exceeding 500 ships and delivery slots booked years in advance. That scale lets the company absorb the cost of experimentation — including automated welding robots that failed roughly 1,000 test welds over ten months before reaching production reliability — in a way that smaller, narrowly focused naval contractors cannot. Twelve CSSC-owned yards alone build virtually all of China’s modern naval fleet, meaning the commercial order book effectively subsidizes and sustains the skilled workforce, supply chains, and heavy infrastructure the navy depends on. State financing, cheap capital from state-backed banks, and a domestic steel industry producing over a billion tonnes annually complete the picture.

Why American Yards Can’t Match the Tempo

The United States retains extraordinary technological sophistication in submarines and carriers, but not speed or volume. Government Accountability Office findings cited in defense-sector reporting show Arleigh Burke-class destroyers delayed between 22 and 58 months, Virginia-class attack submarines delivered roughly three years late, and the Columbia-class ballistic-missile submarine running at least 18 months behind schedule. Skilled-labor shortages, aging facilities, and fragmented supply chains compound the problem. Washington’s response has leaned on allies rather than domestic revival alone: South Korea’s Hanwha purchased the Philadelphia Shipyard in 2024 and aims to scale U.S. output toward 20 ships annually, while a 2023 Korea-U.S. strategic investment package earmarked roughly $150 billion toward shipbuilding cooperation. Analysts note this partnership can, at best, bring the U.S. toward parity with South Korea — not with China.

What the Trajectory Means Going Forward

Even with a modest year-on-year dip in China’s 2025 new-order share, from 74.1 percent to 69 percent, the structural dominance shows no sign of reversing; independent projections continue to anticipate that China will hold 55 to 70 percent of global completions, orders, and backlog on a five-year horizon. The Center for Strategic and International Studies projects the PLA Navy expanding to roughly 425 ships by 2030, already exceeding the U.S. Navy’s battle-force count. The strategic consequence is straightforward: naval power in a prolonged conflict depends less on any single warship’s technology than on the industrial capacity to build, repair, and replace ships faster than they are lost. On that measure, the gap between the two fleets is not narrowing — it is the central fact any serious assessment of Pacific naval balance must now start from.
