The main purpose of an icebreaker is to plough through ice in rivers, harbors, and polar regions to open a path for the navigation or material supply of other ships. Every icebreaker has a strengthened hull, with a "L-shaped" bow. She can smash ice up to 90cm thick usually. (The "Arktika", a Russian nuclear-powered icebreaker launched in 1974, can break ice as thick as 240cm .) An icebreaker can also drive her bow straight over a very thick ice sheet and glide on top of it. The ice sheet will give way under the weight of her hull.
