Which class of submarine is nuclear-powered in China's navy?

The class of submarine that is nuclear-powered in China's navy is the Shang class. These submarines are part of China's modern nuclear submarine fleet and are designed for a variety of roles, including anti-surface and anti-submarine warfare, as well as strategic deterrence through ballistic missile capabilities. The Shang class features advanced technologies and is considered a significant step forward in China's undersea warfare capabilities.

The Yuan class submarines are diesel-electric, primarily focusing on conventional warfare and are not nuclear-powered. The Jin class submarines, on the other hand, are also nuclear-powered but are specifically designed for ballistic missile missions, rather than the general multi-role capabilities offered by the Shang class. Similarly, the Luyang class refers to a type of destroyer, which does not pertain to submarines at all. Each of these classes has distinct roles and technological advancements, highlighting China's evolving naval capabilities.
