one in the stern, and carried 23 torpedoes for them. Armour The Lord Nelsons armour scheme was derived from that of the King Edward VII class, although the vertical armour was generally thicker and the deck armour slightly thinner. The waterline main belt was composed of Krupp cemented armour (KCA) 12-inches thick, although it thinned to at its lower edge. It was high of which was below the waterline at normal load. The thickest portion of the belt extended for approximately amidships, from the rear of the forward 12-inch barbette to abreast the rear main-gun barbette. It was thick from there to the stern while the portion abreast the forward barbette was thick and then reduced to 6 inches to the bow. Below the belt at the stem, a strake of armour projected downwards to support the ship's plow-type ram. The middle strake consisted of armour plates; it continued forward to the bow, albeit in 6- then 4-inch thicknesses. Aft it terminated in an oblique 8-inch bulkhead that connected the armour to the aft barbette. The upper strake of armour was also 8 inches thick, but only covered the area between the main-gun barbettes with oblique bulkheads of the same thickness connecting the side armour to the barbettes to form the armoured citadel. The main gun turret faces and sides were 12 inches thick and their roofs were protected by 3- and 4-inch plates. Their barbettes also had 12 inches of armour on their external faces down to the main deck. Below this the forward barbette's armour reduced to 8 inches down to the middle deck while the aft barbette retained its full thickness down to the middle deck. The inner faces of the barbettes were 3 or 4 inches thick for the forward barbette and 3 inches thick for the aft barbette. The 9.2-inch gun turret faces had 8-inch armour plating, their sides were thick and they had 2-inch thick roofs. The turrets sat on 6-inch thick armoured bases and their ammunition hoists were protected by 2-inch armoured tubes. The upper deck over the citadel was thick and the main deck forward of the citadel to the bow had a thickness of inches. The middle deck inside the citadel was thick on the flat, but 2 inches thick where it sloped downwards to meet the bottom edge of the waterline belt. The lower deck was 4 inches thick where
