As warships do not carry regimental colours, battle honours are instead displayed on a battle honour board. This is usually a solid wooden board (traditionally teak) mounted on the ship's superstructure, carved with the ship's badge and scrolls naming the ship and the associated honours, and either left completely unpainted, or with the lettering painted gold. The size of the board and number of scrolls is dependent on the number of honours earned by a ship and her predecessors, although it is common for blank scrolls to be included in a design. Other designs are also in use: these include plaques for the ship and honours mounted on a backing board, or the details painted onto a flat board.
