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.
