In its strictest sense, a flagship is any naval vessel on which a flag officer is embarked. Some navies have permanent flagships, a designation which may be either functional (ships specifically intended for use by a fleet commander) or ceremonial (a fleet's most prestigious vessel due to its age, size, or some special characteristic).
