 The waterline armour belt consisted of 6 inches (152 mm) of Krupp cemented armour roughly between the fore and aft 7.5-inch gun turrets, but was reduced in steps to three inches to the ends of the ship. The gun turrets and barbettes were protected by 6 – 8 inches (152 – 203 mm) of armour. The thickness of the lower deck was 1.5 – 2 inches (38 – 51 mm). The armour of the conning tower was 10 inches (254 mm) thick.
