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.
