USCGC Northwind (WAG/WAGB 282) was a , the second United States Coast Guard Cutter of her class to bear the name. She was built to replace which was in Soviet lend lease service. During her career, Northwind conducted extensive oceanography, hydrography and cartography studies, as well as icebreaking, during Operation Nanook and Operation Highjump. Northwind was the last Wind class icebreaker when she was decommissioned in Wilmington, North Carolina on 20 January 1989 after 44 years of service.

Northwind was one of the icebreakers designed by Lieutenant Commander Edward Thiele of the United States Coast Guard 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 fifth of seven completed ships of the of icebreakers operated by the United States Coast Guard. She was laid down on 20 July 1944 at Western Pipe and Steel Company shipyards in San Pedro, California, launched on 25 February 1945 and commissioned on 28 July 1945. Rear Admiral Ralph W. Dempwolf, Commander, 9th Coast Guard District presided over the ceremony with his wife, Mrs. Mabelle C. Dempwolf, serving as the sponsor. Wind class icebreakers had hulls 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 controllability and resistance to damage. The objective of Operation Nanook was to assist in a Danish American project to establish a radio and weather station in Thule, Greenland. This area later became Thule Air Force Base. During July through September 1946 the first helicopter deployment from a Coast Guard icebreaker occurred an HNS 1 Sikorsky R 4 from Northwind off the Greenland coast. This deployment; in support of the International Ice Patrol, included the first helicopter landings at Thule, Greenland; Crozier Island and Winter Harbor, Melville Island. On 27 July 1946, Northwind was grounded on an uncharted pinnacle while entering Dundas Harbour, Devon Island, Nunavut but was refloated ten hours later without serious damage.

From December 1946 through January 1947 Northwind participated in Operation Highjump as part of Central Group (Task Group 68), under the command of Captain Charles W. Thomas, with one of the operation's primary missions being to establish the research base Little America IV. She was the only United States Coast Guard vessel to participate in the naval exercise and became the first U. S. Coast Guard cutter to cross the Antarctic Circle. She also completed the first major rescue missions of a submarine beset in ice when she twice broke out the damaged Sennet. Northwind also rescued Mount Olympus, Yancey, and Merrick which were beset and damaged in the ice floe at the Antarctic Circle. The first helicopter flight to base Little America IV from Northwind took place on 15 January 1947. Her crew played the first baseball game, the first double header (all without lights), and the first golf tournament in Antarctica.

During May to August 1948 Northwind conducted her first Bering Sea Patrol, the first in eight years, as the patrol had been suspended during World War II. She functioned as a "floating court" for a United States federal judge and staff, while U. S. Coast Guard medical personnel and United States Public Health Service officers on board provided medical and dental aid to hundreds of isolated Aleutian villagers. She also delivered and dispatched the U. S. Mail for remote Arctic outposts, lightships and lighthouses. She performed law enforcement, oceanographic and hydrographic research, re supplying remote units, ethnological studies of the Aleuts,
In 1949 Northwind returned to the Arctic and in subsequent years served on several U. S. Navy expeditions to the region,

In 1952 Northwind broke the polar icebreaking record for miles sailed north of the Arctic Circle in one season: 10029 mile (16140 km). She was the first ship to break through into Thule, Greenland as early as 28 May 1952 although Thule is normally ice locked until summer. During 1953 Northwind conducted a Bering Sea Patrol. During this patrol Northwind freed USS LST 1048 which was beset in the Beaufort Sea near Barter Island Alaska. USS LST 1048 was on a supply mission to support Distant Early Warning Line construction and was freed by ice demolition. From 12 July to 29 September 1954 Northwind participated in the Canadian U. S. Beaufort Sea Expedition. The mission was to perform an oceanographic and hydrographic surveys of the waters surrounding Banks Island. She was accompanied by HMCS Labrador and Burton Island. This cruise was the first where vessels transited McClure Strait and circumnavigated Banks Island. The transit was completed on 4 September 1954. From February through April 1955 Northwind sailed on a Bering Sea scientific expedition in support of the U. S. Naval Hydrographic Office. During July through September 1955 Northwind supported Distant Early Warning Line operations. From November 1956 through April 1957 Northwind participated in Operation Deep Freeze II, in expeditions to Antarctica, providing clear passage for the cargo ships including USNS Private John Towle. On 20 January 1957 a small gathering of ship personnel, including Sir Edmund Hillary and Capt John Wiis, master of USNS Towle commemorated the opening of Scott's Base, Pram Point Antarctica. The expedition vessels were all part of Task Force 43, in the Antarctic. In mid October 1965 Northwind escorted the disabled Swedish MV Orion in the North Atlantic, while in 40 feet (12 m) seas, to the Gulf of Saint Lawrence, Canada. In 1966 Northwind returned to Fairway Rock and the crew helped install a strontium 90 radioisotope thermoelectric generator and additional oceanographic sensors. Northwind then cruised the Laptev Sea and East Siberian Sea doing oceanographic surveys. From July through August 1967, Northwind conducted a current and hydrographic survey in the Bering Strait and resupplied Fairway Rock. From September to November 1967, Northwind was beset by ice 450 mile (724 km) north northwest of Point Barrow, Alaska. She was freed by CCGS John A. Macdonald, , and
Between March and September 1968, she provided ice escort for the National Science Foundation research vessel RV Alpha Helix, then operated by the Scripps Institute of Oceanography at La Jolla, California. This operation was conducted in the Bering Sea.

From 20 January through 9 April 1970 Northwind conducted an Eastern Arctic patrol and oceanographic cruise. The cutter's northernmost penetration into the Arctic pack ice was at on 13 March 1970. This broke her 1967 surface vessel record by 9 mile (14 km), and set a new record. From 23 June through 28 September 1970 Northwind served on Arctic Operations. Her duties included laying cables, oceanographic studies, and re supplying the Distant Early Warning Line. From 1971 to 1972 Northwind sailed on Operation Deep Freeze to the Antarctic. She was once again in the Antarctic for Operation Deep Freeze from 1972 to 1973. During June and July 1973 Northwind conducted oceanographic research in Alaskan waters. On 1 January 1974 Venzke Glacier in Antarctica was named for Captain N. C. Venzke, USCG; who commanded Northwind from 1971 to 1973. From 1973 to 1975 Northwind underwent extensive machinery modernization and electronic modification at the U. S. Coast Guard Yard at Curtis Bay, Maryland and was stationed in Baltimore, Maryland. During the summer of 1975, Northwind conducted an Arctic East Summer cruise. From mid February 1976 until mid April 1976 Northwind conducted an Arctic Winter East (AWE) cruise in Baffin Bay between Greenland and Canada. From 6 October 1976 to 13 April 1977 Northwind broke ice during Operation Deep Freeze with Task Force 99 in Antarctica. On 16 February 1984 Northwind accomplished the MEDEVAC of a woman from a 33 feet (10 m) sailing vessel 200 mile (322 km) west of Bermuda. On 5 August 1984 Northwind assisted a personal craft off Kulusuk, Greenland. On 4 November 1984 Northwind seized P/C Alexi I, 240 mile (386 km) southwest of Jamaica carrying of marijuana. Northwind was participating in Operation Wagonwheel Forces an inter agency narcotics interdiction effort in the Caribbean from 31 October to 31 November 1984. She became the first icebreaker to make a narcotics seizure and broke the previous tonnage record set by This was a marijuana seizure record (for an icebreaker) that stands as of 2015. From 2 to 21 July 1986 Northwind assisted the Danish and Greenland governments in reestablishing a musk ox herd in northwest Greenland. The last mission of Northwind was an Arctic East Summer (AES) 1988 cruise, the Coordinated Eastern Arctic Experiment (CEAREX). Her role was to serve as ice escort for the Norwegian research vessel, RV Polarbjørn. Northwind broke ice in the Norwegian and Greenland Seas, northward to the Svalbard archipelago of Norway from September 1988 through October 1988. Northwind then returned to homeport in Wilmington, North Carolina, having steamed over 25,000 miles.

Northwind was decommissioned in Wilmington, North Carolina on 20 January 1989 and transferred to the James River Reserve Fleet Northwind was scrapped at International Shipbreakers, Port of Brownsville, Texas in 1999. The scrapping operation took nearly six months to complete.
