The Submarine Rescue Diving Recompression System (SRDRS) is a remotely operated underwater vehicle and its associated systems intended to replace the Mystic class deep submergence rescue vehicle for the United States Navy. Based on the Royal Australian Navy Submarine rescue vehicle Remora, the system is capable of rapidly deploying to a designated location, mounting to a vessel of opportunity, detecting and preparing the area around a downed submarine and submerging to great depths (2000 ft/600m) to give aid and retrieve members of its crew. The SDRS then allows for the decompression of the crew.
