Mir Submersibles  Mir I and Mir II are battery-powered, three-person submersibles with a maximum operating depth of 6,000 m (20,000 ft). This deep-diving capability ranks the Mir vehicles among the deepest diving submersibles ever built, and gives them the capability to reach approximately 98% of the ocean floor.
