Mir was a class of two self-propelled deep-submergence vehicles. The project was initially developed by the USSR Academy of Sciences along with Lazurit Central Design Bureau, and two vehicles were ordered from Finland. The Mir-1 and Mir-2, delivered in 1987, were designed and built by the Finnish company Rauma-Repola's Oceanics subsidiary. The project was carried out under the supervision of constructors and engineers of the Shirshov Institute of Oceanology.
