Dumuju-class dispatch boat

The Dumuju class is a class of dispatch boat (YFL) currently in service with the People's Liberation Army Navy (PLAN). The exact type still remains unknown, and it has received NATO reporting name Dumuju class, with only a single unit of this class have been confirmed in active service as of mid-2010s.

Ships of this class in PLAN service are designated by a combination of two Chinese characters followed by three-digit number. The second Chinese character is Jiao (交), short for Jiao-Tong-Ting (交通艇), meaning dispatch boat (ferry) in Chinese, because these ships are classified as dispatch boats. The first Chinese character denotes which fleet the ship is service with, with East (Dong, 东) for East Sea Fleet, North (Bei, 北) for North Sea Fleet, and South (Nan, 南) for South Sea Fleet. However, the pennant numbers are subject to change due to changes of Chinese naval ships naming convention, or when units are transferred to different fleets.
