Chinese submarine Changcheng 274

The Chinese submarine Changcheng 274 is a Type 6633 diesel-powered patrol vessel built at the Huangpu Shipyard in Guangzhou. Measuring about 77 meters in length, the vessel features a rounded hull, eight torpedo tubes, and was designed to accommodate a crew of approximately 54 sailors who managed navigation, weapons control, and mechanical systems from its compact interior spaces.

The submarine was originally based on a Soviet Romeo-class design, with China planning to build six examples using Soviet-supplied components. When Cold War tensions halted Soviet shipments, China completed only two vessels of this type and subsequently developed its own parts and design improvements, including superior Chinese-made batteries.

The name Changcheng means "Great Wall" in Chinese, directly linking the vessel to national identity and pride. Visitors can see how this submarine represents a pivotal moment when China developed its own military technology rather than relying solely on foreign designs.

Visitors can walk aboard and explore the submarine's compartments, including the control room, engine areas, and torpedo tubes through accessible passages and small hatches. Guided tours provide insight into the tight working spaces sailors had to navigate, while informational displays explain the vessel's systems and operational history in straightforward terms.

After Soviet shipments ceased, the vessel was outfitted with Chinese-made batteries that proved more reliable than the original Soviet versions. This improvisation demonstrated China's resourcefulness in rapidly developing independent technical solutions during Cold War tensions.
