The USRC Bibb was an innovative iron-hulled steamboat built in Pittsburgh in 1845, named after Secretary of the Treasury George M. Bibb. Crafted by the Fort Pitt Foundry, she was part of a broader effort to revitalize American shipbuilding in Pittsburgh after the decline following the War of 1812, driven by the advent of steam power and iron hulls. Constructed as an iron screw steamer, Bibb was distinguished by her experimental "Hunter wheel" propulsion system—paddle wheels mounted horizontally within the hull, enclosed in waterline cases, an innovation devised by Lieutenant William W. Hunter. Although promising in theory, this design proved a failure compared to the more successful screw propulsion. Bibb was launched suddenly on March 8, 1845, with an unfortunate incident where two workmen were injured, one fatally. She initially mounted eight guns and set off down the Ohio River toward New Orleans, but early on, she encountered mechanical difficulties, springing a leak at Cincinnati. An inquiry attributed the leak to packing around a paddle wheel shaft, leading to her being rebuilt in Cincinnati with stronger frames, a more powerful engine, and conventional side-mounted paddle wheels. Completed by 1846, Bibb was stationed at New Orleans under Captain Winslow Foster, serving in various roles including coastal scouting, mail and supply transport, convoy, and towing duties. During the Mexican–American War, Bibb participated in blockade operations off the Mexican coast, supporting larger vessels and performing patrol and convoy tasks. After her wartime service, she returned to Boston in 1847 and was transferred to the United States Coast Survey. Her engines were later salvaged for a subsequent vessel, USS Bibb (1853), often considered a rebuild of the original, marking her as a notable example of early American iron steamship experimentation and military service.
