10 years anniversary of deep manned submersibles MIR-1 and MIR-2

In December 1987 two deep manned submersibles MIR-1 and MIR-2 were completed and tested in the open ocean. In February 1988 the first scientific expedition with new vehicles, which were installed on board of the r/v Akademik Mstislav Keldysh, was conducted at the TAG hydrothermal site in the Atlantic. During the last ten years twenty two scientific and technical cruises with the MIR submersibles were made to different areas of the Pacific, Indian, Atlantic and Polar oceans. In present paper a brief review of the expeditions with scientific purposes, as well as a short introduction of the cruises to the RMS Titanic and nuclear submarine wreck Komsomolets are provided. The operations with the MIR submersibles were quite noticeable for international cooperation in the field of oceanographic research.
