Deep Submergence Vehicles are deep diving manned submarines that are self-propelled. The term DSV is generally one used by the United States Navy, though several navies operate vehicles that can be accurately described as DSVs. DSVs are commonly divided into two types: research DSVs, which are used for exploration, and surveying, and DSRVs (Deep Submergence Rescue Vehicle), which can be used for rescuing the crew of a sunken submarine and/or clandestine (espionage) missions. DSRV type vessels are equipped with docking chambers to allow personnel ingress/egress via a manhole. The United States Navy (USN) is the branch of the United States armed forces responsible for naval operations. ...
U.S. Navy Deep Submergence Rescue Vehicle (DSRV) - Mystic Arrival of the DSRV Avalon at Brest airport aboard a C-5 Galaxy cargo A U.S. Navy Deep Submergence Rescue Vehicle (DSRV) performs rescue operations on submerged, disabled submarines of the U.S. Navy or foreign navies. ...
The real-life feasibility of any DSRV-based rescue attempt is hotly debated, because the few available docking chambers of a stricken submarine may be flooded, trapping the sailors still alive in other dry compartments. Because of these difficulties, the use of integrated crew escape capsules and/or detachable conning tower has gained favour in military submarine design during the last two decades and most DSRV are now primarily relegated to clandestine missions and undersea military equipment maintenance, if at all. The rapid development of safe, cost-saving ROV technology has also rendered some DSV vessels obsolete. Remotely operated vehicles (ROV) are mobile tools used in environments too dangerous for humans. ...
Strictly speaking bathyscaphes are not submarines, because they have minimal mobility, and are built like a balloon, using an inhabitable spherical pressure vessel hung under a liquid hydrocarbon filled float drum. In a DSV/DSRV type vehicle the passanger compartment and the ballast tank functionality is incorporated into a single structure to afford more habitable space (for up to 24 people in case of a DSRV rescue vehicle). Trieste A bathyscape or bathyscaphe is a self-propelled deep-sea diving submersible, consisting of a crew cabin similar to a bathysphere suspended below a float filled with a buoyant liquid such as petrol. ...
Most DSV/DSRV vehicles are powered by traditional electric battery propulsion and have very limited endurance. Plans have been made to equip DSVs with closed circuit internal combustion powerplants (LOX Stirling engines) but none have been realized so far, due to cost and maintenance considerations. All DSV vehicles are dependent upon a surface support ship or a mother submarine, that can piggyback or tow them (in case of the NR-1) to the scene of operations. Some DSRV vessels are air transportable in very large military cargo planes to speed up deployment in case of emergency rescue missions. An internal combustion engine is an engine that is powered by the expansion of hot combustion products of fuel directly acting within an engine. ...

Trieste class bathyscaphe - DSV-0 Trieste - the X-1 Trieste bathyscaphe has reached Challenger Deep, the world's deepest seabed. It was retired in 1966 [1]
- DSV-1 X-2 Trieste II - an updated bathyscathe (or bathyscaph) design, participated in clandestine missions, it was retired in 1984 [2]

The Challenger Deep is the deepest known point in the oceans, 10,911 meters (35,797 feet) deep at its maximum, near 11°22′ N 142°36′ E. It is in the Pacific Ocean, off the island of Guam in the Mariana Islands group at the southern end of the...
Trieste II was designed by the Naval Electronic Laboratory, San Diego, California, as a successor to Trieste —the Navys pioneer bathyscape. ...
- Bathyscaphe Archimedes - French-made bathyscaphe, operated around the time of the Trieste, .
Alvin class submarine Alvin, seconded to NOAA Woods Hole National Oceanographic Center, is to be replaced with a super Alvin class of DSVs, approaching the depth capabilities of the Trieste class vessels, but with enhanced mobility, and with more manipulation tools (robotic arms) as compared to the Alvin class. The National Oceanic and Atmospheric Administration (NOAA) is an agency of the United States Department of Commerce. ...
- DSV-2 Alvin - a deep diving sub, can reach only half as deep as the two Triestes went [4]
- DSV-3 Turtle - Alvin's identical sibling, retired 1998, USN [5]
- DSV-4 Sea Cliff - another Alvin class DSV sub, retired 1998, USN [6]
- DSV-5 Nemo - another Alvin class DSV sub, retired 1998, USN [7]]
ALVIN in 1978, a year after first exploring hydrothermal vents. ...
Nerwin class DSVN - NR-1 Nerwin - US Navy nuclear powered research and clandestine DSV submarine, which can roll on the seabed using large ballon wheels [8]

Aluminaut - Aluminaut - a DSV made completely of aluminum by the Reynolds Aluminum Company, for the US Navy, once held the submarine deep diving record [9]

Priz - Priz - a DSRV class of five ships built by the USSR and Russia. The titanium-hulled Priz class are capable of diving to 1000 meters. 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 british ROV in a successful international rescue effort.

Mir - Mir - a strictly civilian (research) class of DSV which were manufactured in Finland for the USSR. These bathyschape-derived vessels can carry three people down to depths of 6000 meters. After visiting and filming the RMS Titanic's wreck, two Mir submersibles and their support ship were loaned to a US Pacific trench surveying mission in the late 1990's and made important discoveries concerning sulphuric based life in "black chimneys".
