Submarine rescue is the process of locating a sunk submarine with survivors on board, and bringing the survivors to safety.[1] 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.[1]
National and international services exist to facilitate the rapid response to submarine emergencies, including the NATO Submarine Rescue System, and within the US navy the Undersea Rescue Command (URC).[2]
