The first USS Naubuc, laid down as a 1,175-ton light-draft monitor at Perine's Union Iron Works, Williamsburgh, NY, was launched 19 October 1864. However, as with others of her class, she was of faulty design and was found to be unseaworthy prior to her completion. She was then converted to a torpedo boat, 4th rate, with one XI-inch Dahlgren smoothbore, and arid Wood-Lay spar torpedo equipment.
