Icebreaker ships are the unsung enablers of Arctic activity. Without them, polar trade, science, and military presence would be either seasonal or impossible year-round. And as the Arctic ice retreats, icebreakers are only becoming more important, strategic assets rather than niche tools. 

An icebreaker is exactly what it sounds like—a specialized ship designed to operate in ice-covered waters. It breaks ice by riding up onto the ice and crushing it with its weight.
