Mir (Russian: “Мир”, world or peace) is a self-propelled Deep Submergence Vehicle. The project was initially developed by the USSR Academy of Sciences (now the Russian Academy of Sciences) along with Design Bureau Lazurith. Later 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.
