USCGC Westwind was a Wind-class icebreaker that served in the United States Coast Guard as USCGC Westwind, the Soviet Navy as the Severni Polius, and again in the U.S. Coast Guard as USCGC Westwind.
Construction
Westwind was one of the icebreakers designed by Lieutenant commanderEdward Thiele and Gibbs & Cox of New York, who modeled them after plans for European icebreakers he obtained before the start of World War II. She was the fourth of seven completed ships of the Wind-class of icebreakers operated by the United States Coast Guard. Her keel was laid on 24 March 1942 at Western Pipe and Steel Company shipyards in San Pedro. She was launched on 31 March 1943 and commissioned on 18 September 1944. Her hull was of unprecedented strength and structural integrity, with a relatively short length in proportion to the great power developed, a cut away forefoot, rounded bottom, and fore, aft and side heeling tanks. Diesel electric machinery was chosen for its controlability and resistance to damage. Westwind, along with the other Wind-class icebreakers, was heavily armed for an icebreaker due to her design being crafted during World War II. Her main battery consisted of two twin-mount 5"/38 caliber gun| deck guns. Her anti-aircraft weaponry consisted of three quad-mounted Bofors 40 mm anti-aircraft autocannons. and six Oerlikon 20 mm autocannons. She also carried six K-gun depth charge projectors and a Hedgehog as anti-submarine weapons. After her return from Soviet service she received a single 5”38 cal. mount forward and a helicopter deck aft. Sometime after 1966 she had the forward mount removed.
History
The ship's keel was laid at Western Pipe & Steel, San Pedro, California, USA, on 24 August 1942. It was launched from San Pedro on 31 March 1943, and commissioned as the USS Westwind AGB-6 on 18 September 1944. On 21 February 1945 the ship was transferred to the Soviet Union and renamed Severni Polius. On 19 December 1951, the ship was returned to the United States Coast Guard, and recommissioned as the Westwind on 22 September 1952 after a refit. Starting 30 September 1954, the ship participated in a 121-day Arctic cruise, returning to New York Harbor, Brooklyn Navy Yard. In 1955 the Westwind called at Bouvetøya in the Southern Ocean at the request of the South African government. Between 1956 and 1957, the ship was engaged in DEWLINE support Operations in the Arctic. In 1962, the ship was part of SUNEC '62 - hull stress tests conducted for the design of future Icebreakers. In 1964 the Westwind arrived in the area of United States Coast Guard LORAN Station Cape Atholl, Greenland, returning from this Arctic cruise on 18 August of that year. On 22 June 1966 the ship crossed the Arctic Circle at 52N 03W on SUNEC66 Supply Northeast Command out of Thule, Greenland. On 3 March 1967, as part of Deep Freeze 67, the ship crossed the Antarctic Circle at 67S 36W and assisted Navy Seabees building a scientific station on Palmer Peninsula. From June to September 1970 the ship was on Arctic East Deployment. Between 1974 and 1975 the ship underwent an extensive refit to strengthen the bow, replace engines, change propeller shafts, and received a new "Icebreaker Red" paint scheme. From 1976 to 1981 the ship's homeport was Milwaukee, Wisconsin. During this period the ship embarked on Summer North Trips to the Arctic Circle via Montreal, St. John's, Newfoundland, and on to Thule, Greenland for summer breakouts. On December 13, 1977, during a preliminary test run for Winter Breakouts in the Great Lakes, it ran aground at Seven Foot Shoals, near the entrance to St. Mary's River, Lake Huron. The resulting by gash and bent propeller shaft was repaired at a dry dock in Montreal over a period of 4 months. The summer of 1978 saw another Arctic trip, doing mapping and marine science along the northeastern coast of Greenland. On August 29, 1979 , again in the Arctic, the Westwind reached 79 degrees North Latitude, the farthest any U.S. surface vessel had ever penetrated. In 1982 the ship was involved in an operation out of Mobile, Alabama, the Haitian Migration Interdiction Operation. Following this operation, Cutter Westwind's home port changed to Mobile. In 1984, the Westwind sustained major hull damage in the Weddell Sea on a Deep Freeze cruise. A tall, long tear in the hull was temporarily patched by the crew until it could be repaired in South America. In 1986, funding cuts reduced operating funds for icebreakers, ending plans to refit the Westwind. The ship was finally decommissioned on 28 February 1988.
