China’s first Type 095 Sui-class nuclear-powered attack submarine has just been spotted preparing for sea trials at the Bohai Shipbuilding Heavy Industry Company shipyard in Huludao.
Featuring an X-tail rudder, likely pump-jet propulsor, and a wider hull optimized for quieter operations, the Type 095 represents China’s most ambitious attack submarine yet—one that could shift the balance of undersea power in the Pacific.
The Type 095 Has an X-Tail Rudder and Likely Pump-Jet Propulsor — Designed to Reduce Cavitation and Minimize Propeller Noise

Those preparations are taking place at the Bohai Shipbuilding Heavy Industry Company (BSHIC) shipyard at Huludao, in Liaoning Province.
BSHIC is one of Beijing’s largest shipyards and was established in the mid-1950s. It is China’s first and still only shipyard for the construction of nuclear-powered submarines.
The Type 095, also known as the Type 09V, is a significant step in the expansion of Chinese undersea forces.
Like most of the PLAN’s construction, the tempo of shipbuilding continues to outpace that of U.S. submarine production.
Naval strategists and analysts of the PLAN say the Type 095’s entry into service will affect the overall balance of power in the Pacific.
Among other concerns, the expanding PLAN submarine fleet allows an increase in the density and frequency of Beijing’s undersea patrols in the western Pacific.
This has considerable implications for Taiwan’s security.
Chinese President Xi Jinping has stated his intentions to invade the island democracy, and many Western observers believe a takeover could be attempted as early as 2027.

New Design Techniques
There are notable design changes in the Type 095, which is officially a third-generation submarine of the PLAN class.
These alterations may result from lessons learned from the operations of previous-generation designs.
One of the more visible changes is the Type 095’s X-tail rudder.
Submarine design specialists say this is likely accompanied by a pump-jet propulsor. It could reduce propeller noise, thereby minimizing cavitation.
The sub also has a wider hull than its predecessor model, the Type 093 Shang-class.
Design specialists believe this is another sign of a significant improvement in quietness.
The Type 095 is often compared to the U.S. Seawolf-class, largely due to its size.
The Type 095 appears to be slightly shorter than the Type 093 but is almost one meter wider.
As naval analyst H.I. Sutton has pointed out, there is “a hydrodynamic logic in Seawolf’s specifications.”
“Like a whale or other marine creature, there is an optimum length-to-beam ratio which optimizes drag and allows the creature to go faster or use less energy. Counter-intuitively, the shorter-fatter Seawolf has a much more efficient hull design than the later, more compromised, Virginia-class,” Sutton writes.
The Type 095 appears to be designed for that sweet spot, or what submarine design analysts call a “golden ratio.”
Mission Profile
The Type 095 is designed to include vertical launch missile cells for enhanced anti-ship and land-attack capabilities.
One of the central mission functions, aside from hitting targets in preparation for larger military operations, is protecting aircraft carrier task forces
Between 2021 and 2025, the PLAN launched 10 nuclear-powered submarines collectively totaling 79,000 tons.
This is markedly greater output than the U.S. shipyard output during the same timeframe, of 7 boats for a total of 55,000 tons.
The launch of the Type 09V/Type 095 will be a watershed moment, with China reaching a 1+2 tempo of annual nuclear submarine production in the 2024–25 period. This is an industrial output equal to the U.S. Navy’s target for 2028.
The Type 095’s introduction would mark the PLAN’s dual milestone: the launch of a new class of submarine and the continuation of an accelerated industrial tempo that the United States is currently unable to match.
