There is only one shipyard in the country up to the task. But that yard has been undergoing a massive enlargement. And now, recent satellite imagery suggests an additional capacity expansion.

Just how many nuclear submarines China will build over the next ten years is a hot topic. The Office of Naval Intelligence (ONI) recently forecast China’s submarine fleet to grow by six nuclear-powered attack submarines by 2030. Other observers, such as retired Capt. James Fanell who was Director of Intelligence and Information Operations for the U.S. Navy’s Pacific Fleet, place their estimates even higher. What seems clear is that the number of nuclear submarines will increase.

The new hall is estimated to be large enough to allow construction of two submarines simultaneously. When added to the other hall recently constructed, that would allow four boats to be in the sheds at once. And there is another much older construction hall at the other end of the site which, if still active, could add another. So four or five boats at once.

The nuclear submarines include both ballistic missile submarines (SSBNs) and attack submarines (SSN). All nuclear submarines are built at the Bohai shipyard, so its capacity will be a major factor in the total fleet strength.

China’s naval growth has not gone unnoticed in Washington. In response, the U.S. Navy will have to adjust. Outlining the proposed Battle Force 2045, Defense Secretary Mark Esper said that the U.S. must begin building three Virginia Class submarines per year as soon as possible. This would build a “larger and more capable submarine force”. The proposed force will include 70-80 attack submarines, described as “the most survival strike platform in a future great powers conflict”.

There are three new classes of submarine which might be built at Bohai. The most straightforward is the Type-09IIIB (also written Type-093B). This is an iterative improvement on the current Type-09IIIA Shang-II Class submarine. The main improvement expected is the inclusion of cruise missiles in vertical launch tubes. These will allow it to carry an increased load of cruise missiles, improving its strategic strike capability. The YJ-18 cruise missiles are generally analogous to the Russian Kalibr family of missiles. China already operates Kalibr from some of its submarines.

More advanced than the Type-09III family is the next-generation Type-09V Tang Class (aka Type -095). This is expected to be everything the Type-09IIIB is, and also stealthier.

The third projected type is a next-generation ballistic missile submarine (SSBN). the Type-09VI (Type-096) will follow the current generation Type-09IV Jin Class (Type-094). They are expected to augment the six Type-09IV instead of replacing them, leading to a net increase in China’s SSBN fleet. The 2020 China Military Power Report to Congress projected an increase to eight SSBNs by 2030.
