Chinese submarine Changcheng 279, type 033 diesel submarine
The Chinese submarine Changcheng 279 is a Type 033 diesel-electric submarine now located as a museum vessel in Huancui District. Its long, narrow hull with gray exterior displays simple, functional features including a periscope tower and smooth surfaces designed for underwater operation.
The submarine entered service in 1982 and served in the East Sea Fleet for approximately 29 years before decommissioning in 2003. After its active service, it was converted into a museum vessel to preserve China's submarine development and naval capabilities for future generations.
The submarine carries the name Changcheng, meaning Great Wall, which symbolizes strength and protection in Chinese maritime culture. Many of China's submarines use this naming tradition to reflect the continuity and importance of the nation's naval efforts.
Visitors can walk around the exterior and view the submarine up close, with some interior sections accessible through guided tours. The site provides clear signage and informative panels that make it easy to understand the vessel's history and technical features.
The submarine was originally used to test new missile technologies and improve submarine tactics, making it an important research tool rather than purely operational. This lesser-known role reveals that the vessel served a vital function in advancing China's naval capabilities beyond standard deployment.
