The self-unloading bulk freighter John G. Munson (2) was built in 1952 as hull # 415 by Manitowoc Shipbuilding, Inc., Manitowoc, WI. The construction was a result of a contract awarded to Manitowoc Shipbuilding by Irvin L. Clymer, president of Bradley Transportation Line in 1950. The new vessel was to be used in the stone trade, limestone in particular. The new self-unloader was launched November 28, 1951 for the Bradley Transportation Line, Rogers City, MI which was part of the Michigan Lime and Chemical Co. division of U.S. Steel Corp. The John G. Munson completed her sea trials on August 12, 1952 and departed on her maiden voyage August 21, 1952 bound for Calcite, MI and her first of many loads of limestone. Of note, the president of Bradley's sister fleet Pittsburgh Steamship Co. also owned by U.S. Steel Corp. announced in 1950 the awarding of contracts to build 3 bulk carriers coincidentally of similar size and power to the Munson but not self-unloaders. Unknown at the time would be the classification confusion later as the 2 fleets amalgamated.

The John G. Munson was named after Mr. John Gephart Munson. Mr. Munson was elected president of both Michigan Limestone and its Bradley Transportation Division until 1939 when he became a vice president for the parent United States Steel Corp. He retained this position until his retirement in 1951. Mr. Munson died March 28, 1952. This was the second vessel in the Bradley Transportation Co. fleet to bear the John G. Munson name. The John G. Munson (1) was built as a self-unloader in 1917 by the American Ship Building Co., Lorain, OH as the Carl. D. Bradley for the Bradley Transportation Co. She was renamed John G. Munson (1) in 1927, holding this name until 1951 at which time she was renamed Irvin L. Clymer. This renaming freed the Munson name to be applied to the current vessel. The first Munson's dimensions were 552' (168.25m) loa x 60' (18.29m) beam x 32' 9.75m) depth, 11,920 ton (12,111 mt) capacity. She was powered by a shipyard built 2,100 i.h.p. (1,567 KW) triple expansion steam engine. The vessel was dismantled for scrap in Duluth, MN in 1994-95.

The John G. Munson's dimensions at the time of her launch were 666' 03" (203.07m) loa x 72' 00" (21.95m) beam x 36' 00" (10.97m) depth. Six holds were serviced by 18 hatches where the vessel had a 20,900 ton (21,236 mt) capacity at a mid-summer draft of 25' 10" (7.86m). The holds had the cubic capacity to carry 18,000 net tons of coal (equivalent to 16,175 tons or 16,330 mt). Coal-fired Foster-Wheeler water tube boilers fed a General Electric cross compound steam turbine engine rated at 7,700 s.h.p.(5,744 KW) built by General Electric Co., Lynn, MA. The power was fed to a single fixed pitch propeller giving her a speed of 16 m.p.h. The vessel was rebuilt during the 1975-76 winter lay-up including the addition of a 102' (31.09m) mid-section, automating and converting her coal-fired boilers to burn heavy fuel oil and the installation of a bow thruster. The work was completed by Fraser Shipyards, Superior, WI. The Munson's stern thruster was installed later as it was originally the bow thruster removed from the Enders. M. Voorhees in May of 1986. Her 22 hatches service 7 holds where she is capable of carrying 25,550 tons (25,960 mt) at a mid-summer draft of 27' 04" (8.33m). The holds now have the cubic capacity to handle 21,990 net tons of coal (equivalent to 19,634 tons or 19,949 mt). The 250' (76.20m) forward mounted self-unloading boom can be swung 110 degrees to port or starboard and can discharge at a rate of up to 5,600 net tons per hour.
On June 5, 1981; U.S. Steel turned its fleet into an owned subsidiary renaming it USS Great Lakes Fleet and designating it as a common carrier. This designation allowed the fleet's management to seek business opportunities elsewhere while fulfilling the transportation requirements of U.S. Steel. The Munson, though, retained her Bradley grey hull color until 1990 when she was painted her current fleet color scheme. When U.S. Steel completely divested itself from any involvement in transportation, the John G. Munson and her fleet mates then sailed for the new fleet owners USS Great Lakes Fleet, Inc., Duluth, MN; a subsidiary of Great Lakes Transportation, Monroeville, PA. By 2003, the fleet name was shortened to just Great Lakes Fleet, Inc. Then in 2004, Great Lakes Fleet, Inc. was acquired by CN Rail (Canadian National Railway Co., Montreal, QC). The fleet remains U.S.-flagged and based in Duluth but now sails under the management of Keystone Shipping Co., Bala-Cynwyd, PA in compliance with the Jones Act.
