USCG Polar Class Icebreaker
The USCG Polar class of heavy icebreakers consists of three vessels, the USCGC Polar Star (WAGB-10), the USCGC Polar Sea (WAGB-11), and the USCGC Healy (WAGB-20). These cutters, specifically designed for open-water icebreaking have reinforced hulls, special icebreaking bows, and a system that allows rapid shifting of ballast to increase the effectiveness of their icebreaking.
