China just launched more nuclear submarines than America in tonnage and numbers for the first time ever, signaling a stealthy shift in global undersea power that could upend Pacific dominance.
Story Snapshot
- China launched 10 nuclear-powered subs (79,000 tonnes) from 2021-2025, topping US’s 7 (55,000 tonnes).
- Bohai Shipyard expansions enabled parallel production of Type 094 SSBNs and Type 093B SSGNs.
- Marks Beijing’s nuclear triad completion despite US qualitative edges in stealth technology.
- IISS report warns of growing challenge amid US shipbuilding delays until Columbia-class in 2028.
- China’s fleet at ~16 subs vs US 63 active, but rapid output closes the gap.
China’s Huludao Shipyard Surge
Bohai Shipbuilding Heavy Industry Co in Huludao expanded from 2019-2022 with a second manufacturing hall. This state-owned facility became China’s sole nuclear submarine producer. Workers launched 10 vessels between 2021 and 2025, including seventh and eighth Type 094 Jin-class ballistic-missile submarines in 2024-2025 and nine Type 093B Shang III guided-missile subs. Satellite imagery in early 2026 confirmed six Type 094s at sites, inferring hidden launches. Total displacement hit 79,000 tonnes, exceeding US output.
People’s Liberation Army Navy operates these subs for nuclear deterrence and blue-water expansion. Type 094s carry nuclear-armed missiles, completing China’s triad with land ICBMs and bombers. Type 093B features vertical launch systems for hypersonic threats. Huludao’s parallel lines shifted China from diesel-electric reliance, rooted in 1970s Type 091 Han-class origins through 2010s Type 093 upgrades.
US Production Lags Behind
US Navy launched seven nuclear subs totaling 55,000 tonnes in the same period, focusing on Virginia-class attack subs. Aging fleet of 63 active vessels faces retirements without matching output. Columbia-class SSBNs delay until around 2028 due to industrial base constraints. AUKUS pact promises tech sharing with allies, but timelines slip. State control gives China speed; US lifecycle mixes SSNs and SSBNs, slowing rates.
IISS analysts Henry Boyd and Tom Waldwyn detailed this in their February 2026 Military Balance blog. They cite US assessments and satellite data showing China’s quantitative lead. Chinese subs remain noisier, limiting stealth against superior US Virginia and Ohio classes. Yet numbers pressure tracking in vast Pacific and Indian Oceans.
Strategic Implications Unfold
Short-term, China extends reach, pressuring Japan, India, and South Korea. Long-term, Type 096 SSBNs by 2030s aim for qualitative leaps with JL-4 missiles targeting US mainland. US risks undersea crisis without shipyard revival. Beijing gains prestige; Washington strains budgets. Regional tensions rise as PLAN projects power.
The Chinese Navy has “dramatically increased” submarine production and could soon deploy a new vessel that’s able to hit “large portions” of the US with nuclear missiles from Chinese waters, according to the US Navy https://t.co/DG9XPOvq1J

Experts at Forecast International note China starts from behind with ~16 subs but prioritizes gaps. Popular Mechanics calls it troubling for US Asian edge. IISS deems it a production milestone, not instant dominance—noise trumps numbers per common sense. Facts align with conservative calls for industrial investment over endless delays.
