USS Atka (AGB-3) was a Wind-class icebreaker commissioned by the United States Navy in 1950. Originally built as USCGC Southwind (WAGB-280) for the United States Coast Guard during World War II, she was transferred to the Navy and renamed Atka. Throughout her service, Atka played a crucial role in Arctic and Antarctic operations, conducting supply missions, scientific support, and icebreaking duties. In 1966, she was returned to the Coast Guard, resuming her original name and continuing polar service before being decommissioned in 1974.
