China’s futuristic stealth sub to boost ‘hunt-and-kill’ capabilities: experts
Satellite images show a new Chinese submarine under construction with a finless design that analysts say could improve stealth and speed.

Chinese military analysts say a new submarine spotted at Jiangnan Shipyard appears to have a finless design, a feature they believe could improve underwater performance. The vessel’s exact configuration is still unclear, but it suggests China is pushing its submarine fleet in a more advanced direction.
A new Chinese submarine has been seen from space while it is being built. It seems to have a smoother shape that could help it move faster, hide better, and turn more easily, like a fish with less drag in the water.
Analysis
What was spotted
Satellite images cited by France-based Naval News show a submarine under construction at Jiangnan Shipyard in Shanghai. The key detail is that it appears to lack a traditional fin, the tower-like structure usually found on top of a submarine for observation and communications.
Why analysts care
Chinese analysts quoted in the article say a finless layout could improve stealth, manoeuvrability and speed. That is why they see it as part of Beijing’s effort to improve its “hunt-and-kill” capabilities, meaning the ability to find and destroy targets more effectively under water.
What is still unknown
The article stresses that the exact configuration of the vessel is unclear. China does not normally announce details about military platforms while they are still being built, so the public view comes mainly from satellite imagery and outside analysis.
Bigger picture
This is described as the second new Chinese submarine type identified through satellite images this year. That suggests China’s submarine force is expanding quickly, even if many of the details remain hidden. Retired PLA colonel and military commentator Yue Gang said Beijing is “seeking the limits of underwater performance,” which captures the article’s central interpretation: China is continuing to push for better quietness, speed and agility beneath the surface.
Key points
- Satellite images suggest a new Chinese submarine is being built at Jiangnan Shipyard in Shanghai.
- The vessel appears to lack a traditional fin, which analysts say could improve stealth, manoeuvrability and speed.
- The submarine’s exact configuration is still unclear because China does not usually disclose details of military platforms under construction.
- It is the second new Chinese submarine type identified through satellite imagery this year.
- A retired PLA colonel said Beijing is seeking the limits of underwater performance.
If the design works as analysts expect, it could improve the submarine’s stealth and handling. That would give China a more capable undersea platform and show that its shipbuilding and naval engineering are advancing quickly.
The article makes clear that the submarine’s exact design is still unknown, so outside observers may be reading too much into satellite images. If the finless layout does not perform as hoped, the claimed gains in speed, manoeuvrability or stealth may not fully materialize.
