Mystic class is a class of Deep-Submergence Rescue Vehicles (DSRVs), designed for rescue operations on submerged, disabled submarines of the United States Navy or foreign navies. The two submarines of the class were never used for this purpose, and were replaced by the Submarine Rescue Diving Recompression System.
A deep-submergence vehicle (DSV) is a deep-diving crewed submersible that is self-propelled. 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, which are intended to be used for rescuing the crew of a sunken navy submarine, clandestine (espionage) missions, or both. DSRVs are equipped with docking chambers to allow personnel ingress and egress via a manhole.
The Italian Navy is the navy of the Italian Republic. It is one of the four branches of Italian Armed Forces and was formed in 1946 from what remained of the Regia Marina after World War II. As of August 2014, the Italian Navy had a strength of 30,923 active personnel, with approximately 184 vessels in service, including minor auxiliary vessels. It is considered a multiregional and a blue-water navy.
Trieste II(DSV-1) was the successor to Trieste – the United States Navy's first bathyscaphe purchased from its Swiss designers.
The Italian Special Forces include special forces units from several branches of the Italian Armed Forces: the Esercito Italiano (Army), the Marina Militare (Navy), the Aeronautica Militare and the Arma dei Carabinieri (Gendarmerie).
AS-28 is a Priz-class deep-submergence rescue vehicle of the Russian Navy, which entered service in 1986. It was designed for submarine rescue operations by the Lazurit Design Bureau in Nizhny Novgorod. It is 13.5 m (44 ft) long, 5.7 m (19 ft) high, and can operate up to a depth of 1,000 m (3,300 ft).
A deep-submergence rescue vehicle (DSRV) is a type of deep-submergence vehicle used for rescue of personnel from disabled submarines and submersibles. While DSRV is the term most often used by the United States Navy, other nations have different designations for their equivalent vehicles.
COMSUBIN is the Italian Navy's special operations unit.
The NATO Submarine Rescue System (NSRS) is a tri-national project to develop an international submarine rescue system. The system provides a rescue capability primarily to the partner nations of France, Norway and the United Kingdom, but also to NATO and allied nations and to any submarine equipped with a suitable mating surface around its hatches.
A submarine rescue ship is a surface support ship for submarine rescue and deep-sea salvage operations. Methods employed include the McCann Rescue Chamber, deep-submergence rescue vehicles (DSRV's) and diving operations.
Elettra is an Italian Navy SIGINT vessel designated as 'Nuova Unità Polivalente di Supporto (NUPS).
Designed to carry out research and surveillance activities, the vessel's platform was developed from the RV Alliance built for NATO.
Her propulsion system, based on two permanent magnet electric engines, constitutes a technological breakthrough and she is the first surface vessel in the world to be powered by this type of engine. The main characteristics of this propulsion system are: high reliability, high efficiency, low maintenance and low underwater radiated noise
The Marino class of diving support vessels consists of two units operated by the Italian Marina Militare. The vessels are used by Comando Subacquei Incursori (COMSUBIN) for training and operational duties and are named MAS Motoscafo Appoggio Subacquei.
SRV-300 is a deep-submergence rescue vehicle that is rated to dive up to 300 m (980 ft). It was built by DRASS (Livorno) for the Marina Militare, and is capable of descending to 300 metres (980 ft) carrying 12 passengers in addition to crew. SRV-300 is hosted by Anteo, berthed at La Spezia.
MSM-1 USEL was a deep-submergence rescue vehicle (DSRV) that was rated to dive up to 600 m (1,969 ft). It was built by Cantieri Navali Ernesto Breda/Fincantieri for the Marina Militare. The sub was capable of descending to 600 metres (2,000 ft) below the surface and could carry 8 passengers at a time in addition to her crew. MSM-1 USEL was hosted by mother ship Anteo at La Spezia from 1980 to 2002. That year MSM-1 USEL was replaced by the DRASS Galeazzi SRV-300.
USSP is a planned Submarine rescue ship of the Marina Militare, financed with 2017's balance law.
It is expected to replace Italian ship Anteo.
Drass, or DRASS, is an Italian manufacturing company headquartered in Livorno, whose best known for their range of midget submarine and swimmer delivery vehicle. They also have a line of hyperbaric chambers for diver decompression.
The following is the structure of the Italian Navy as of June 2020. It is considered a multiregional and a blue-water navy.
JS Chiyoda (ASR-404) is a submarine rescue ship of Japan Maritime Self-Defense Force.
Submarine rescue is the process of locating a sunk submarine with survivors on board, and bringing the survivors to safety. This may be done by recovering the vessel to the surface first, or by transferring the trapped personnel to a rescue bell or deep-submergence rescue vehicle to bring them to the surface. Submarine rescue may be done at pressures between ambient at depth, and sea level atmospheric pressure, depending on the condition of the distressed vessel and the equipment used for the rescue. Self-rescue of submarine personnel by buoyant free ascent at ambient pressure is considered submarine escape. Survivors may require recompression treatment for decompression illness.
