ThePeople's Republic of China developed aclass of35-ton deep-submergence rescue vehicle^[1][3] (DSRV) for thePeople's Liberation Army Navy (PLAN). It was first tested in 1986^[2] and operational in 1989.^[1]

The DSRV may perform a rescue at depths up to 200 metres (660 ft). Six^[2] or 22 survivors could be carried.^[1][3] This suited contemporary PLAN submarines which deployed infrequently and typically to coastal waters.^[1]

The submarine may also perform salvage work. It has a manipulator arm and adiving chamber for six divers.^[3]
