The USCGC Onondaga (WPG-79) was a United States Coast Guard cutter constructed by Defoe Boat Works in Bay City, Michigan, and commissioned on September 11, 1934. She was a notable vessel in Coast Guard service, measuring approximately 165 feet in length with a beam of about 23 feet, designed for law enforcement, rescue, and patrol duties. Her initial station was at Astoria, Oregon, where she contributed significantly to law enforcement, including efforts to prevent out-of-season halibut fishing and to assist ships in distress, notably patrolling the pelagic seal migration to the Pribilof Islands. Following the transfer of the Coast Guard to the U.S. Navy in November 1941, Onondaga's role expanded to include military patrol and escort duties in the Alaskan region. Her operations frequently involved patrolling between Seattle, Washington, and Ketchikan, Alaska, and she participated in key wartime activities during World War II. She was involved in the defense of Dutch Harbor, Alaska, during Japanese air attacks in June 1942, where she and other vessels responded swiftly to the Japanese carrier strikes, shooting down at least one enemy aircraft and aiding in the general wartime effort in the Aleutian Islands. Throughout her service in World War II, Onondaga was part of a broader naval effort to monitor and defend Alaska from Japanese advances, often operating alongside other Coast Guard cutters, Navy destroyers, and patrol vessels as part of the Northern Pacific Force. Her duties included patrol, escort, and search operations in the challenging weather conditions of the Alaskan waters. She remained on active patrol until the end of the war, after which she returned to the U.S. Treasury Department on January 1, 1946. Notably, Onondaga participated in rescuing survivors from the SS Yukon near Seward, Alaska, in February 1946. She was decommissioned on July 24, 1947, and later sold in 1954 to the Foss Launch and Tug Company of Seattle. In 2011, her hull was surveyed and found to be sunk at a pier in the Lake Washington Ship Canal, with no pollutants present. The vessel's historical significance includes her wartime service in the Aleutians and her contributions to maritime law enforcement and rescue efforts, making her a vessel of considerable importance in U.S. Coast Guard history.
