The USCGC Westwind (WAGB-281) was a distinguished Wind-class icebreaker built for the United States Coast Guard during World War II. Laid down on 24 March 1942 at the Western Pipe and Steel Company shipyards in San Pedro, California, she was launched on 31 March 1943 and commissioned on 18 September 1944. As a Wind-class vessel, Westwind featured a robust hull designed with unprecedented strength and structural integrity, characterized by a relatively short length compared to its considerable power. The hull incorporated a cut-away forefoot, rounded bottom, and heeling tanks on the fore, aft, and sides, optimizing her icebreaking capabilities. Power was supplied through diesel-electric machinery, offering controllability and damage resistance, essential for her Arctic and Antarctic missions. Originally armed for wartime service, Westwind's armament included two twin-mount 5-inch (130 mm) deck guns, three quad-mounted Bofors 40 mm autocannons, six Oerlikon 20 mm autocannons, six K-gun depth charge projectors, and a Hedgehog anti-submarine weapon. After her Soviet service as Severni Polius, she was refitted to include a single 5-inch38 cal. mount forward and a helicopter deck aft, with some modifications such as the removal of the forward mount after 1966. Throughout her service, Westwind participated in numerous Arctic and Antarctic missions, supporting DEWLINE operations, conducting hull stress tests for future icebreaker design, and engaging in scientific and exploratory cruises. Notable events include crossing the Arctic Circle in 1966 and the Antarctic Circle during Operation Deep Freeze in 1967. She also supported scientific stations and conducted icebreaking operations on the Great Lakes. In 1977, she ran aground near Lake Huron, resulting in a significant hull gash that was repaired over several months. Decommissioned on 28 February 1988, Westwind's final fate is believed to have been sale for scrap, with reports indicating she was moored in Honolulu en route to scrappers. Her service history underscores her importance as a versatile and resilient icebreaker, contributing significantly to Arctic, Antarctic exploration, and maritime safety operations during her nearly five decades of service.
