The sides of the circular turrets were 12 inches thick, and they had roofs. The conning tower had walls. Turret hoists, voicepipes and electrical leads were protected by armored tubes.

Along the center of the ship, they were one inch thick, but increased to two inches closer to the sides of the ship.
