USS Catawba was a single-turreted Canonicus-class monitor built for the Union Navy during the American Civil War. Completed shortly after the end of the war, Catawba was laid up until sold to her builders in 1868, and then resold to the Peruvian Navy. Renamed BAP Atahualpa, the ship participated in the defense of main port of Peru, Callao, during the War of the Pacific. When the city of Lima was taken by Chilean troops in 1881, she was scuttled to prevent her capture. Atahualpa was later refloated and used as a storage hulk until scrapped in the early 20th century.

Originally named USS Tippecanoe, after the river in Indiana, USS Wyandotte was a single-turreted Canonicus-class monitor built for the Union Navy during the American Civil War. Completed after the end of the war, Wyandotte was laid up until 1876, although she received her new name in 1869. The ship was commissioned in 1876 and assigned to the North Atlantic Squadron for the next three years. She became a receiving ship in 1879 until she was placed in reserve again in 1885. Wyandotte was on militia duty when the Spanish–American War began and she was recommissioned in 1898 to defend Boston, Massachusetts from any Spanish raiders. The ship was decommissioned after the end of the war and sold for scrap in 1899.
