China's Nuclear Submarine Surge Reshapes Naval Power, Posing Long-Term Geopolitical Risks

Mike Brookes, the US Navy's intelligence director. This transition marks a fundamental departure from historical patterns, moving away from a fleet predominantly composed of diesel-electric vessels.

Supported by substantial investments in three shipyards over the past decade, China has dramatically increased its nuclear submarine production rate from less than one boat annually to significantly higher levels. The PLAN, currently operating over 60 submarines with at least 14 nuclear-powered, is projected to expand to approximately 70 by 2027 and around 80 by 2035, with about half expected to be nuclear-powered.

New designs like the Type 041 Zhou-class, Type 095 guided-missile, and Type 096 ballistic missile submarines are incorporating advanced reactor designs, sensors, and noise-quieting technologies. Notably, the Type 096, equipped with JL-4 ballistic missiles, could target large portions of the US from protected waters near China.

This expansion enables Chinese submarines to operate longer and farther from home, complicating US naval operations and challenging US and allied dominance in the Indo-Pacific and potentially globally, aligning with China's broader blue-water naval ambitions.
