  • Zhishui-I, the first model which is rumored used as a training and teaching aid instead of being deployed in the field. Development begun in 1989 & it entered service in 1994.
  • Zhishui-II, which won the 1st place of China [Shipbuilding Industry Corporation] Science and Technology Advancement Award. Development begun in 1989 concurrently with Zhishui-I, and it entered service in 1994.
  • Zhishui-III, development begun in 1996 and was completed in July, 2000, and it subsequently entered Chinese service aftering winning 1st place of National Defense Science and Technology Advancement Award in 2001, and 2nd place in National Science and Technology Advancement Award in 2002.
  • Zhishui-IV, entered service after development completed in 2005.
  • Zhishui-V, latest model of the series, first reveled in October 2011.
Zhishui-III has a similar appearance to earlier Explorer AUV, with a cylindrical body resembling a miniature submarine without the conning tower.

The two shrouded propellers are installed just below the horizontal control surfaces of the crucifix control surfaces at the stern. Zhishui class AUV is claimed to be capable of performing a variety of tasks by the designers, but no details are released because it is designed for military application from the start, as opposed to other Chinese AUVs that are also used for civilian applications.
