"Lord Clyde"s original armament was replaced during her 1870 refit with a pair of RML nine-inch guns and 14 RML eight-inch guns; she only retained a pair of her original seven-inch guns. The latter guns remained in position as forward chase guns on the main deck; one of the guns became the chase gun on the upper deck and the other replaced the pair of seven-inch aft chase guns on the main deck. Also on the upper deck were a pair of guns on the broadside and the remaining 12 eight-inch guns were mounted on the main deck on the broadside amidships.
