Baltika (Russian: Балтика) is a Russian icebreaker built by Arctech Helsinki Shipyard in Helsinki, Finland. She is the first ship ever built with an asymmetric hull that allows her to operate not only ahead and astern, but also obliquely (sideways) with a large angle of attack. In this way, the relatively small oblique icebreaker is capable of opening a wide channel in ice for large merchant ships.
