Satellite Images Expose China’s New ‘Sail-Free’ Mystery Submarine Designed To Evade US Defences

Satellite Images from Shanghai’s Jiangnan Shipyard revealed an advanced Chinese submarine without a traditional sail.

The design of the vessel has caught the attention of experts, along with its highly streamlined hull.

While the U.S and Western countries are struggling to produce even 2 submarines annually, China has launched 15 to 20 submarines, some belonging to new classes, in the last 5 years.

The new submarine is 120 m long and has a narrower beam than other Chinese submarines; it might not serve as a ballistic missile submarine.

This is because China’s new JL-3 submarine-launched ballistic missiles need larger launch compartments.

It also has an X-shaped stern control surface and a pumpjet propulsor, which reduces underwater noise while the submarine reaches high speeds underwater.

The submarine lacks a sail, which is usually used to mount periscopes, communication masts, and snorkel systems.

The removal of this basic design component will enhance its hydrodynamic efficiency, improve submerged speed, manoeuvrability, and make it difficult for enemies to track the submarine.

It remains unclear what kind of propulsion system the new submarine has, but experts say a nuclear reactor would be the most viable choice given its size.

Another possibility is the “nuclear-AIP” technology, which combines a low-power nuclear reactor with air-independent propulsion principles, which offer longer endurance.

China launched a submarine in 2024 using this concept, the Type-041 Zhou-class submarine.

The submarine’s launch also signals that China is now operating simultaneous production lines for several submarine and other naval ship programs.

Beijing has not released any official information regarding this new submarine, which is common since China does not publicly announce such sensitive projects.
