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.
Fyodor Litke (1909 icebreaker)
"Litke" became famous for its Arctic operations in 1932–1935, survived World War II and was retired in 1958 after nearly 50 years of service. Unlike conventional icebreakers that crush ice with their own weight from above, "Litke" belonged to an older generation of vessels, relying on ramming and cutting ice without any downward movement. For this reason, "Litke" was uniquely classified as an "ice-cutter" () or "icebreaking steamship" (), rather than a true icebreaker.
