Kalamazoo, a double turreted monitor, was laid down in 1863 at New York Navy Yard. A larger version of the Miantonomoh class, she had slightly-better freeboard (approx. 45 inches), better lines, and was more adapt at sea keeping than previous versions. Work on the monitor was suspended 27 November 1865 and was never resumed. The unfinished ship was renamed Colossus on 15 June 1869, but she was never launched nor commissioned. While awaiting word as to her status the builders allowed her wooden hull to rot, and she was eventually broken up on the stocks in 1884.
