Icebreaker
In May 2007, sea trials were completed for the nuclear-powered Russian icebreaker NS . The vessel was put into service by Murmansk Shipping Company, which manages all eight Russian state-owned nuclear icebreakers. The keel was originally laid in 1989 by Baltic Works of Leningrad, and the ship was launched in 1993 as NS "Ural". This icebreaker was intended to be the sixth and last of the "Arktika" class, and currently is the world's largest icebreaker.
Moskva (1959 icebreaker)
Moskva (Russian: "Москва") was a Soviet polar icebreaker and the lead ship of a series of five diesel-electric icebreakers named after major Soviet cities. She was built at Wärtsilä Hietalahti shipyard in Helsinki, Finland, in 1960 and was at the time of her delivery the largest and most powerful non-nuclear icebreaker ever built. Shortly after the dissolution of the Soviet Union, "Moskva" was decommissioned after a long and successful career along the Northern Sea Route and sold for scrap in 1992.
