This is meant to be a modified version of SMS Prinz Aldabert, and a follow on to the Bucephalus class of Armored Cruisers.
Like the Regina Elena class, the forecastle is a tumblehome design to allow the waist turrets to bear forward.
To model this, the forecastle is raised, but a long aft deck is fitted. The secondary and tertiary are assigned the aft deck at the appropriate heights.

Main guns are 240L45, firing a 180kg shell. With a 1895 tech of 1700 ME, adjusted for the bore cross section of a 240 vs. 255mm gun, that is 1503 ME, which yeields a Muzzle Velocity of 839m/s. That allows penetration of 308mm of armor at 2000m, and 274mm at 3000m, making the vessel a possible threat to period battleships. By 6000m, penetration falls to 207mm. It is thought that the combo of a 135mm belt and 40mm sloped deck should make the ship resistant to such long range shots.

The intermediate guns are the largest allowed QF weapons, a 165mm L45 firing a 63kg shell at 825m/s. This gun can penetrate 129mm at 3000m, and 87mm at 6000m. As a result, the main belt is 135mm at it's thickest, but is also backed by the slope of the 40mm protective deck.

The 90mm are anti-torpedo boat weapons.

The protective deck is 40mm over the citadel and 25mm over the ends. An additional 20mm deck is fitted over the casement level.

Decks :
+6.02 : Forecastle deck
+3.52 : Weather deck, 20mm over casements
+1.22 Top of main belt.guards against diving shells against slope of protective deck.
+1.02 : Gun deck, crown of 40mm protective deck, top of 25mm decks and end belts
