Chinese Navy's Submarine Developments and Infrastructure Expansion in 2025
In 2025, the Chinese Navy (PLAN) focused on transitioning from conventionally powered submarines to nuclear-powered designs, notably the Type 09IIIB. Bohai shipyard in Huludao is the sole builder for these submarines with an estimated production of seven by late 2025.
The operational fleet may include six Type 09III/A-SSNs and six Type 09IV/A-SSBNs. Meanwhile, construction of conventionally powered submarines has slowed. Wuchang Shipbuilding launched four Hangor-class submarines for Pakistan.
Additional Type 903 replenishment oilers are under construction, potentially increasing capacity for carrier strike groups. Naval infrastructure is expanding, particularly at bases in Yulin and Qingdao.
Experimental efforts include amphibious barges and uncrewed systems, though operational capabilities remain unclear. Investment in the military-industrial complex is driving innovation, leading to various proposals and developments.
