; [[Priz]] : a DSRV class of five ships built by the USSR and Russia. The [[titanium]]-hulled Priz class are capable of diving to {{convert|1000|m|mi}}. These mini-submarines can ferry up to 20 people for very brief periods of time (in case of a rescue mission) or operate submerged for two to three days with a regular crew of three to four specialists. In early 2005, the Russian AS-28 Priz vessel was trapped undersea and subsequently freed by a [[United Kingdom|British]] [[Remotely operated underwater vehicle|ROV]] in a successful international rescue effort.
