About U-455
U-455 is a historic German submarine wreck off Genoa that is reserved for highly qualified technical teams. The wreck sits in open water on a steep technical profile, with variable visibility, current, and rich encrusting life that reward careful planning rather than casual sightseeing or easy turnaround; expedition logistics matter more than convenience.
