Similar to the OTL Von Der Taan in battery layout, with the mid ships turrets en echlon.

Main belt is -2m to +2m WL, with the upper belt carrying to freeboard.

The armor deck is split between a 30mm deck capping the upper belt and the main 50mm deck capping the main belt, bolstered over the magazines and machinery (since the upper deck doesn't cover ends).
