It can be connected to a transfer chamber for TUP operations and the design may be influencing that of the new US system. The Korean LR5K is in fact based on the UK design, which itself was adapted for rescue from an offshore submersible built in 1978. Little is know about Russia's systems, one submersible of the Bester and five of the Priz class, which were involved in the failed rescue attempt on the Kursk. The Priz is thought to be operable either manned or unmanned, but is restricted by a battery endurance of just three hours. An upgrade has been proposed that will allow the Russian systems to dock with damaged submarines and improve their navigation equipment.
China also has DSRV capability.
