Modern icebreakers are the most marvellous of civilian ships. They are huge, they are strong, they are powerful, and their history is amazing. Without them, there would be no safe waterways for other ships in the icy waters around the poles of the Earth. Here is a spectacular look into their evolution, from steamers and diesel vessels to nuclear powered ships.
