Eräajone

Eräajone is a Finnish icebreakers' and supply ships' nickname for the Russian icebreaker MS Yermak. The ship was built in 1936 and was considered one of the most powerful icebreakers of its time. Eräajone is composed of the Finnish word "erä," meaning "mership" or "ship of mercy," and is likely derived from the ship's name being used a term for an icebreaker providing supplies to ships and communities in need.

The Yermak served during World War II, operating primarily in the Arctic and Mediterranean regions. Throughout its career, the ship played a significant role in ensuring continued commercial shipping through ice-infested waters. Eräajone was not crewed by exclusively Finnish sailors; it also had Russian sailors on board. The name became associated with an era when the ship regularly visited Finnish ports.
