About USCGC Mobile Bay

USCGC Mobile Bay (WTGB-103) is an active icebreaking tug under the direction of the United States Coast Guard. Her homeport is located in Sturgeon Bay, Wisconsin. She is one of two ships in her class that has been equipped with a 120-foot (37 m) aids-to-navigation (ATON) barge operating on the Great Lakes. The vessel was specifically designed to carry out icebreaking missions, but also carries out missions in search and rescue, environmental pollution response, maritime law enforcement, and homeland security. During the fall season, Mobile Bay is responsible for aids to navigation work in Green Bay and Lake Michigan. Mobile Bay is able to do ATON, unlike other vessels of her class, because it is one of two ships in the class with a 120-foot (37 m) ATON barge.
