USS Francis Scott Key

USS Francis Scott Key (SSBN-657), a Benjamin Franklin-class ballistic missile submarine, was the only submarine of the United States Navy to be named for Francis Scott Key (1779–1843), an American lawyer, author, and amateur poet who wrote the poem "The Defense of Fort McHenry", which became the words to the United States' national anthem, "The Star-Spangled Banner". During World War II there was a liberty ship named SS Francis Scott Key.
