Nanshui 701-class water tanker

Nanshui 701 class water tanker is a class of little known naval auxiliary ship currently in service with the People's Liberation Army Navy (PLAN). 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.

Nanshui 701 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 Shui (水), meaning water, because these ships are classified as water tankers. 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.
