Construction of the United States Coast Guard Cutter Mackinaw was started on March 20, 1943 by the Toledo Shipbuilding Company. The company went into bankruptcy during construction and the American Shipbuilding & Dry-dock Company completed the Mackinaw and launched it on March 4, 1944 at a cost of $10,000,000. The Mackinaw was been stationed in Cheboygan, Michigan from its commissioning on December 30, 1944. 

When first commissioned, the Mackinaw was the most powerful  icebreaker in the world. At the conclusion of her career, the Mackinaw was still the largest United States Coast Guard Cutter assigned to the Great Lakes and set the standards by which other icebreakers are measured. The Mackinaw is the only "Mackinaw" class icebreaker which was built and its design borrows from the "Wind" class. 

At full load the Mackinaw displaced 5,252.4 tons and drew 19' 2.25" of water. Her innovative features included a 12 foot diameter bow propeller which draws water from beneath the ice ahead, both weakening the ice and sending water along the sides of the hull and reducing ice friction. The Mackinaw also has a heeling system which can shift nearly 112,000 gallons of ballast water from side to side in 90 seconds, allowing a rocking motion which assists the Mackinaw in freeing itself from ice.

The Mackinaw had a compliment of 8 officers and 67 elicited men and women. The last members of the ship's compliment will left the Mackinaw at on June 30, 2006, turning the Mackinaw over to Icebreaker Mackinaw Maritime Museum (IMMM).

Why "WAGB?"   The "W" has been applied to all Coast Guard ships since W.W.II. During the war, to avoid problems that could arise from a Navy and Coast Guard ship having the same number on their bows, a "W" was painted before the number to signify the ship as a Coast Guard ship. The "AGB" is for Arctic Glacier Breaker. The Polar Rollers (Polar Star, Polar Sea) and Healy are also WAGB's.  The "AGB" is for Arctic Glacier Breaker.
