USCGC Onondaga (WPG-79), a United States Coast Guard cutter, was built by Defoe Boat Works in Bay City, Michigan, commissioned on 11 September 1934. From her commissioning until 1941, Onondaga was stationed at Astoria, Oregon, where she performed important law enforcement duties and rendered much assistance to ships in distress. Each year she patrolled the annual pelagic seal migration to the Pribilof Islands, and she attempted to prevent out of season halibut fishing.
