A comment argues that the all-forward layout becomes more attractive once all-or-nothing armour is available. The game model keeps the alternative ships within the earlier design setting and gives every version a turtleback scheme as the best available period option. This choice sets a boundary on the counterfactual. It tests triple turrets and revised layouts without importing every later battleship innovation at once.

Turtleback armour before all-or-nothing protection
The alternative all-forward battleships retain a turtleback scheme because all-or-nothing armour lies outside the period design options being tested.
