Beijun 204 classdredger is a class of little known navalauxiliary ship currently in service with thePeople's Liberation Army Navy (PLAN).^[1] The name of this class is after the first unit commissioned, with the exact type still remains unknown, and only a single unit of this class have been confirmed in active service as of mid-2010s.^[1] In comparison to other dredger in Chinese military service, Beijun 204 class is also capable of performing floatingpile driver missions with two piles it is equipped with, one on each side of the ship.

Beijun 204 class series ships in PLAN service are designated by a combination of two Chinese characters followed by three-digit number. The second Chinese character is Jun (浚), meaning dredge in Chinese, because these ships are classified asdredgers. The first Chinese character denotes which fleet the ship is service with, with East (Dong, 东) forEast Sea Fleet, North (Bei, 北) forNorth Sea Fleet, and South (Nan, 南) forSouth Sea Fleet. However, the pennant numbers may have changed due to the change of Chinese naval ships naming convention.
