Great Lakes Fleet

Great Lakes Fleet, Inc., is a shipping firm headquartered in Duluth, Minnesota. It operates a fleet of nine self-unloading bulk carriers on the Great Lakes, which transport dry bulk cargo such as iron ore, coal and limestone.

History

Great Lakes Fleet was formed on July 1, 1967, when U.S. Steel consolidated its Great Lakes shipping operations by merging the Pittsburgh Steamship Division and its sister fleet, the Bradley Transportation Company forming the USS Great Lakes Fleet.
In 1981, Great Lakes Fleet was spun off into a U.S. Steel–owned subsidiary, Transtar, Inc.
