The Stevens Battery was an early design for a type of ironclad, first proposed in 1841 for use by the United States Navy. A revolutionary design with potential capabilities far beyond the norm for her times, she might have set a new standard in naval design for the time if she had put to sea in the 1840s, 1850s, or 1860s. One full-sized example was begun, but attempts in the following decades to complete the ship to three different designs all failed thanks to extensive construction delays and a lack of funding. Construction finally was abandoned in 1874, and she was sold for scrapping in 1881 without ever being launched.
