Chinese Next-Generation Submarine Developments Spotted In New Satellite Imagery

Recent satellite imagery of a shipyard in northeastern China offers interesting new insights into the country’s next-generation submarine developments. The images notably show a pumpjet propulsor and other features worth examining on an example of what is generally described as a new class of nuclear-powered attack submarine, or SSN.

TWZ has obtained a new image taken on September 18 of the submarine in question, which is being built at the Bohai Shipyard in Huludao, from Vantor. Janes reported on this submarine earlier today, based on a separate Vantor image from September 1. The outlet also described the boat as a Type 095, something we will come back to later on.

As mentioned, the pumpjet propulsor immediately stands out in both images. This is also understood to be a feature on the Type 093B nuclear-powered attack submarine, a significantly improved variation on that earlier design, which first emerged in the early 2020s. Compared to traditional exposed propellers and more basic shrouded types, pumpjets offer benefits for quieter operation and efficiencies, especially at higher submerged speeds.

The recent imagery also highlights the submarine’s X-shaped stern plane arrangement. This is not found on the Type 093B, which is considered to be something a bridge between that class and the next-generation design. Broadly speaking, an X-shaped configuration offers advantages when it comes to enhanced maneuverability, efficiency, and safety, which can be particularly useful in littoral environments. It can also provide benefits when it comes to acoustic signature reductions across significant parts of the submarine’s operating envelope compared to the cruciform stern planes.

Another Chinese submarine design that emerged in 2024, currently referred to as the Type 041 or Zhou class, and that is understood to feature a hybrid nuclear/conventional propulsion system, also has an X-shaped stern configuration. The first known example of the Type 041 came to light after it appeared to have sunk in a shipyard.

An X-shaped stern arrangement also looks to be a feature on yet another new class of submarine that appeared at the JN (Jiangnan) Shipyard in Shanghai earlier this year. Initial reports also suggested that the design lacked a traditional sail. However, it has been confirmed that it has a sail, but that is very small proportionally to the overall size of the boat. Truncated sails can offer performance and other advantages, but there are trade-offs.

The image of the submarine that Janes obtained also notably shows an open rectangular-shaped section aft of the sail. The September 18 image that we received from Vantor shows a structure placed over that section of that submarine, obscuring ongoing work on that part of the boat. The Type 095 is widely expected to feature some type of vertical launch system (VLS) array able to accommodate a variety of anti-ship and land-attack cruise missiles, as well as potentially hypersonic types. The Type 095 is also sometimes referred to as a guided missile submarine, or SSGN, as a result. The open area seen in the September 1 shot could be where the VLS array is set to be fitted. It might also provide access to the reactor compartment or another area of the submarine.

Interestingly, the September 18 image also shows what look to be at least two relatively large circular openings, side-by-side, at the bow end of the submarine in front of the sail, the purpose of which is not immediately clear. There is a possibility these could also be for vertically launching munitions or other payloads. As a point of comparison, U.S. Virginia class nuclear attack submarines, starting with the Block III version, have two large-diameter Virginia Payload Tubes (VPT), one in front of the other, in the bow in front of their sails. At the same time, the openings on the submarine in Huludao also appear to be in a position that is very close to where the submarine’s main sonar array would be installed, and they could be tied to that aspect of the design, too.

“I think its too early to be sure about the VLS configuration from publicly available imagery. I realize people assume the large rectangular space halfway behind the sail is the VLS, but I am not sure this is the case and I’d caution to jump to conclusions. The space could also be related to work on the reactor compartment,” Alex Luck, a naval analyst who closely tracks submarine and Chinese navy developments, told TWZ. “With Type 093B, the VLS after launch was initially covered with a tarp, and then the installed launchers were readily visible quite quickly during the fitting-out process. The work process may change with these newer boats, but the different appearance during launch and fitting out needs to be considered in that regard.”

“I do expect Type 095 to have a VLS of some sort, but I am not sure as of yet what the configuration would look like, or where exactly it is located,” he added.

The bigger outstanding question may be exactly what type of submarine is currently being built now at the Bohai Shipyard. Based on a review of additional imagery from Planet Labs’ archive, the boat appears to be around 394 feet (120 meters) long. When the first example of what was assessed to be a Type 095 emerged in Huludao in February, it was estimated to have a length of roughly 361 feet (110 meters). The ‘small sail’ design that broke cover earlier this year in Shanghai is also estimated to be some 394 feet/120 meters long based on available imagery, but also looks to be narrower than the boat presumed to be a Type 095 in February.

“One significant question is the nature and difference between the boat launched by Bohai in February, and the two newer hulls launched in late May/early June both by Bohai and at Jiangnan in Shanghai,” Luck, the naval analyst, also told TWZ. “Specifically, we do not quite know whether they are for different operational roles, or rather a two step development for one final configuration of a new SSN. I think the latter is at least plausible.”

“A related question then is what boat we are looking at now with the new imagery, i.e. the February boat or the newer hull Bohai had launched,” he continued. “Without exact and reliable measurements that question for now is unresolved in the public discourse. For now we need more, and more detailed imagery, including of the different boats together, to clarify these aspects.”

“This [September 1] image reinforces my impression that the boat launched in February may have been a one off not including the full spec featured on the notional 095A launched by Bohai and Jiangnan in late May. We’ve already seen both versions side by side in Bohai,” Luck also wrote on X after Janes‘ published its report.

Regardless, the emergence in recent years of so many new, more modern submarines, and across what appear to be several distinct classes, is significant. It is no secret that China’s People’s Liberation Army Navy (PLAN) is working to significantly expand the size and capabilities of its submarine force with a clear eye toward extending operations further and further out in the Pacific, at least. In the past, U.S. officials have publicly said the overall quality of newer Chinese submarines has been getting closer in parity to American designs.

“The PLA Navy is executing a significant strategic shift from diesel-electric to all-nuclear construction, representing a fundamental departure from historical construction patterns,” U.S. Navy Rear Adm. Mike Brookes, head of the Office of Naval Intelligence, wrote in prepared remarks ahead of a hearing before members of the U.S.-China Economic and Security Review Commission in March.

In particular, the Type 095, as well as the new Type 096 nuclear-powered ballistic missile submarine, “represent next-generation platforms expected to enter service during the late 2020s through 2030s,” Brookes also wrote at that time. “These submarines will incorporate substantial advancements in nuclear reactor design, sensor performance, weapons integration, and noise quieting technologies.”

Submarine modernization efforts are just one aspect of a larger effort by the PLAN to expand its capabilities above and below the waves. Chinese shipyards have also been producing ever-more capable aircraft carriers, amphibious assault ships, destroyers, frigates, and more in recent years, as well. The pace of China’s construction of new surface ships and submarines has also been growing, creating a particularly significant and still-widening disparity in this regard with the U.S. Navy. This is something that has become increasingly concerning, as TWZ routinely highlights.

Work in Huludao, as well as shipyards elsewhere in China, is certainly already revealing interesting new insights into China’s next-generation submarine efforts.
