The weather deck over the citadel consists of homogeneous armor over plating; the main armor deck varied depending on the space it was protecting. Over the magazines, the main armor deck was homogeneous armor laminated on a deck plating inboard and on 12 mm plating outboard. Over the machinery spaces, the main armor deck was on 12 mm plating inboard and on 12 mm plating outboard. The main armor deck extends to the bow and stern, where it thinned to over plating and over plating respectively.
