What Happened to the Carthaginian Navy?

Rome discovers an intact Carthaginian naval vessel and the parts are numbered so they can figure out how to create a new one okay maybe. They revive the Corvus a kind of movable landing ramp that can extend a gangplank for Marines to the other ship which was used by the by the Sicilians in past wars. That enables them instantly to defeat the Carthaginian Navy in a massive battle as big as anything up to the battle of the naval battles of World War II.
