Comparative operational data (e.g., number of cutters, icebreaking hours, geographic coverage) confirm that Operation Taconite is larger than other U.S. domestic icebreaking operations.
Multiple U.S. Coast Guard and regional official releases and agency materials describe Operation Taconite as the Coast Guard’s largest domestic icebreaking operation; U.S. Coast Guard Sector Northern Great Lakes and Ninth District documentation identify Taconite as the primary, large-scale Great Lakes icebreaking mission covering Lake Superior, Lake Michigan, the St. Marys River, the Straits of Mackinac and Georgian Bay. Given authoritative Coast Guard/Ninth District sources and repeated official statements, the claim is True: Operation Taconite is the largest domestic icebreaking operation in the United States.
