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]
