Dongjun 434 class dredger is a class of little known naval auxiliary ship currently in service with the People'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] Dongjun 434 is one of the few Chinese naval ships made by western countries, and it is built by DEMAG.^[1]

Dongjun 434 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 as dredgers. 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 may have changed due to the change of Chinese naval ships naming convention.
