The German Type 212 class, also Italian Todaro class, is a diesel-electric submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German and Italian navies. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens proton exchange membrane (PEM) compressed hydrogen fuel cells. The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free, extremely quiet and virtually undetectable.
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.

The ship's design was developed by the "Ufficio Navi Speciali del Reparto Progetti Navi", according to the guidelines provided by the Navy General Staff. The ship was built at Cantiere Navale Breda di Porto Marghera and commissioned to the Italian Navy on 31 July 1980.
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
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.

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.
