Icebreaker Yermak
Yermak (Ермак) (sometimes spelled Ermak) was the first true icebreaker, constructed for Russia under the supervision of Admiral Stepan Osipovich Makarov. It was named after the famous Russian explorer of Siberia, cossack ataman Yermak Timofeyevich. It was commissioned on October 29, 1898, and on the very first voyage it reached 81°21'N north of Spitsbergen in 1899.
