The turret armour is 10 inches by the ports, and 9 inches elsewhere, which is secured by means of bolts and nuts to an oak backing from 11 inches to 9 inches thick. The backing is secured to upright angle-irons round the turret. An inner lining is formed of ⅜-iron with a space of 10 inches from the backing, to prevent splinters from being driven into the turret when struck by a projectile.
