The People's Republic of China developed a class of 35-ton deep-submergence rescue vehicle[1][3] (DSRV) for the People'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 a diving chamber for six divers.[3]
