- Notes: Intended as commerce destroyers in case Britain were to intervene in the American Civil War. Hull designed by Delano, engines by Isherwood. Very fast but unsuccessful design, the five vessels of the class were Ammonoosuc, Madawaska, Neshaminy, Pompanoosuc, and Wampanoag. On 15 May 1869, they were renamed Iowa, Tennessee, Arizona, Connecticut, and Florida, respectively. The machinery accounted for over 30% of displacement. Wampanoag achieved 17.75 knots on trials, but was condemned for naval purposes in 1869 and laid up until 1874, when she became receiving ship at New London. Two others were never completed, and all were sold or broken up by 1886.
