The USCGC Eastwind (WAGB-279) was a distinguished Wind-class icebreaker built for the United States Coast Guard, with construction commencing with the laying of her keel on June 23, 1942, at Western Pipe and Steel Company in San Pedro. Launched on February 6, 1943, and commissioned on June 3, 1944, she was designed with a robust hull featuring unprecedented strength and structural integrity, characterized by a rounded bottom, a cutaway forefoot, and multiple heeling tanks. Her powerplant consisted of diesel-electric machinery, chosen for controllability and damage resistance, enabling her to operate effectively in icy conditions. During World War II, Eastwind was heavily armed, equipped with two twin-mount 5-inch (130 mm) deck guns, three quad-mounted Bofors 40 mm anti-aircraft autocannons, six Oerlikon 20 mm autocannons, and anti-submarine weapons including K-gun depth charges and a Hedgehog. Her armament was indicative of her wartime role, and post-war modifications saw her aft 5-inch mount replaced by a helicopter deck, with her forward mount removed by 1951. Eastwind’s service record includes notable operations such as ferrying 200 US Army troops to capture the last German weather station in Greenland, Edelweiss II, in 1944 and seizing the German trawler Externsteine, which was later commissioned into the US Coast Guard as USCGC Eastbreeze. She sustained a severe collision on January 19, 1949, off Cape May, New Jersey, where she was struck by the tanker SS Gulfstream, resulting in the loss of 13 crewmen and requiring firefighting and rescue assistance from other Coast Guard vessels. In her Arctic and Antarctic missions, Eastwind participated in scientific and exploration activities, including launching stratospheric balloons in 1952, crossing the Antarctic Circle in 1955, and circumnavigating the globe during Operation Deep Freeze in 1960-1961—becoming the first cutter to do so. Her polar expeditions led to geographical features being named after her captains, emphasizing her maritime significance. Eastwind was decommissioned in December 1968, after a career spanning over two decades, and was eventually sold for scrap in 1972. Her service history underscores her role in Arctic exploration, wartime defense, and scientific research, making her a pivotal vessel in US Coast Guard history.
