The Martha L. Black-class icebreakers are a class of six light icebreaker and buoy tenders constructed for and operated by the Canadian Coast Guard. Built in the 1980s, the class operates on both coasts of Canada and have been used for operations in the Arctic region, including the search for the ships of Franklin's lost expedition. They are rated as "high endurance multi-tasked vessels" under Canadian Coast Guard naming rules.
