China just outlaunched America in nuclear submarines for the first time ever, launching 10 advanced vessels to the US’s 7 between 2021 and 2025—igniting fears of a Pacific power shift.
Story Snapshot
- China’s 10 nuclear subs (79,000 tonnes) surpassed US’s 7 (55,000 tonnes) in 2021-2025, per IISS February 2026 report.
- Huludao shipyard expansions from 2019-2022 enabled parallel production of Type 094 SSBNs and Type 093B SSGNs.
- Marks Beijing’s nuclear triad completion, challenging Western naval dominance despite US qualitative edges.
- US faces aging fleet and delays; Columbia-class SSBNs not until 2028.
- Satellite imagery confirms six Type 094s; more inferred launches ongoing.
China’s Huludao Shipyard Fuels Submarine Surge
Bohai Shipbuilding Heavy Industry Co (BSHIC) in Huludao expanded from 2019 to 2022, adding a second manufacturing hall. This state-owned facility became China’s sole nuclear submarine producer. Between 2021 and 2025, it launched 10 nuclear-powered subs, including the seventh and eighth Type 094 Jin-class ballistic-missile submarines in 2024-2025 and nine Type 093B Shang III guided-missile subs. Total displacement hit 79,000 tonnes, exceeding US output.
People’s Liberation Army Navy (PLAN) operates these vessels. Beijing drives production for nuclear deterrence and blue-water expansion. The launches complete China’s nuclear triad, pairing sea-based power with land ICBMs and bombers. Satellite imagery in early 2026 showed six Type 094s at sites, with reports inferring more hidden builds. IISS analysts Henry Boyd and Tom Waldwyn verified data through US assessments and imagery.
US Production Lags Amid Fleet Aging
US Navy launched seven nuclear subs totaling 55,000 tonnes in the same period, focusing on Virginia-class attack subs. Its fleet holds 63 active nuclear subs against China’s roughly 16, including reserves. Retirements pressure inventory as Columbia-class SSBNs delay until around 2028. AUKUS pact faces hurdles, slowing allied responses. Chinese subs remain noisier, limiting stealth, but numbers challenge tracking in vast oceans.
China’s program evolved from 1970s Type 091 Han-class subs through 2010s Type 093 and 094 upgrades. Type 093B features vertical launch systems; future Type 096 SSBNs aim for 2030s leaps. Early 2026 saw the lead Type 095 Sui-class SSN launch, plus Type 09V SSGN reports with hypersonic capabilities. Huludao now supports parallel builds, signaling sustained output.
Strategic Implications Strain Western Navies
Short-term, China extends reach into Pacific and Indian Oceans, pressuring Japan, India, and South Korea. Long-term, it narrows the quantity gap while enhancing its triad. US risks a looming undersea crisis without industrial revival. Regional tensions rise as Western navies grapple with louder but more numerous Chinese subs. Economic strains hit US budgets for defenses; politically, it underscores Beijing’s ambitions.
IISS labels this a growing challenge, though noise levels curb Chinese operations. Forecast International notes China starts behind but prioritizes tech gaps. Popular Mechanics calls it troubling for US dominance in Asia. Facts align with common sense: numbers matter, but quality endures—urging American investment in shipbuilding to preserve superiority.
