Hello; An icebreaking ship is designed to sail through heavy ice, and provide safe waterways for other boats to sail through. This video is on five amazing ice breaking ships. The ice breaking ships of all the countries are awesome. They are doing so gud. Hats off to the technological skills of their respective country men. "Mostly around Alaska"? The majority of the USCG icebreakers work on the great lakes. The US has exactly 3 dedicated icebreakers NOT on the great lakes, one of which (WAGB 11 Polar Sea) has been decommissioned for several years now. The Polar Star and the Healy are both Arctic/Antarctic icebreakers, and they're both home ported in Seattle. There are USCG ships in Alaska that have SOME icebreaking capabilities, but that is not their primary mission.
