China Navy Unveils Submarine

The People’s Liberation Army Navy placed a large “sailless” submarine at Jiangnan (JN) Shipyard in Shanghai, visible May 31–June 1 2026.
The 120-m (394-ft) vessel, 10-11 m (33-36 ft) wide, features an X-form rudder and minimal sail, a design first seen on a Chinese sub in 2024.
Analysts expect nuclear power but allow for a hybrid Type 041 “Zhou” system, noting that the sub’s appearance on the same day as a Bohudao Type 095 launch caused confusion.

Summary

Rupprecht Shows Sub

On May 29, 2026, @Rupprecht_A posted satellite imagery that appears to show a new 120-meter sail-less submarine at Jiangnan Shipyard.
An analyst notes the image’s low resolution prevents confirming the hull’s exact diameter.
Scaling the picture against the Type 09V hull suggests the vessel is shorter, indicating it is likely not a Type 09V.
The post highlights the difficulty of using open-source satellite photos to verify Chinese naval builds.

History

Historical Context

In December 1953 the U.S. Navy commissioned USS Albacore, an experimental AGSS-569 built to test the single-screw teardrop hull that emerged from 1949 hydrodynamic studies at the David Taylor Model Basin. Its 89-ft hull reached a 33-knot submerged speed, establishing the “Albacore hull” that shaped later attack submarines of navies worldwide.
