China is building a 120-meter nuclear submarine at the Bohai shipyard in Huludao, and new satellite imagery is finally shedding light on its design. Analysts have struggled to fully identify the vessel, but recent photos reveal key features that explain its purpose.
The latest image, taken on September 18, shows a pump-jet propulsion system and an X-shaped stern configuration—details that were previously hidden. These elements suggest a submarine far more advanced than its predecessors.

What the New Satellite Images Reveal
The September 18 image from Bohai clearly shows a pump-jet installed on the new submarine. This technology replaces the conventional propeller and offers efficiency gains, especially in reducing noise at certain speeds.
China has already incorporated pump-jets on its Type 093B submarines, which are seen as a bridge between earlier nuclear attack subs and the next generation. The new vessel, however, takes this a step further.
Another revealing feature is the X-shaped stern control surfaces instead of the traditional cross configuration. This design can improve maneuverability, safety, and efficiency, while also helping to reduce acoustic signature under certain conditions.
Why the X-Rudder Matters
The X-rudder is not entirely new, but its application on a Chinese nuclear submarine of this size is significant. It allows for better control at low speeds and in shallow waters, and it can reduce the risk of damage during docking.
More importantly, the X-configuration contributes to stealth by minimizing the submarine's acoustic footprint. This aligns with China's broader push to modernize its nuclear fleet and enhance its ability to operate undetected.
Unanswered Questions and Strategic Implications
Despite these revelations, analysts still cannot fully explain the submarine's exact role. Is it a next-generation attack submarine, a ballistic missile sub, or a testbed for new technologies? The size—roughly 120 meters—suggests a large vessel capable of long-range missions.
The lack of clarity is partly due to the secretive nature of China's naval programs. However, the visible advancements indicate that Beijing is investing heavily in undersea warfare capabilities.

Key Takeaways
- Pump-jet propulsion on the new sub enhances stealth and efficiency.
- X-shaped stern planes improve maneuverability and reduce noise.
- The submarine is significantly more sophisticated than previous generations.
- Its exact role remains unclear, but it signals China's naval ambitions.
Comparison with Previous Submarines
| Feature | Type 093B | New Submarine |
|---|---|---|
| Propulsion | Pump-jet | Pump-jet (advanced) |
| Stern Configuration | Cross | X |
| Length | ~110 m | ~120 m |
| Stealth | Improved | Enhanced |
The table highlights the evolutionary steps from the Type 093B to the new vessel. While the 093B introduced pump-jet technology, the new sub refines it and adds the X-rudder, making it a leap forward. The background to this story is set out in Trending: latest articles.

What to Watch Next
As more satellite images emerge, analysts will look for signs of weapon systems, sensor arrays, and the submarine's propulsion details. The pace of construction at Bohai will also indicate how quickly China plans to deploy this new class.

FAQ
What is a pump-jet and why is it important?
A pump-jet is a propulsion system that uses a ducted rotor to generate thrust. It is quieter than a conventional propeller, making it harder to detect, which is crucial for submarines.
Why does the X-rudder configuration matter?
The X-rudder improves maneuverability and safety, especially at low speeds, and can reduce acoustic signature. It is a sign of advanced design focused on stealth and control.
What is the role of this new submarine?
Analysts are unsure, but its size and features suggest it could be a next-generation attack submarine or a platform for new technologies. It reflects China's growing undersea warfare capabilities.
How does this compare to other nuclear submarines?
The new sub appears more advanced than China's Type 093B, with refinements in propulsion and control surfaces. It may rival the latest submarines from other major navies.
