The Tegetthoff class already carried twelve 12-inch guns in four triple turrets, giving Austria-Hungary a powerful starting point. A rough gunnery rule of thumb shows why ten 14-inch guns were more than a routine calibre increase: eight would have offered comparable weight under that rule, while the Ersatz Monarch design carried ten, matching the later King George V class in gun count and calibre. Four Tegetthoffs and four Ersatz Monarchs could therefore have formed an eight-ship battle-fleet concentration. These ships needed neither exceptional range nor exceptional speed to remain dangerous in the confined Adriatic, where opponents had little room to avoid them. Italy's first-generation dreadnoughts would have struggled against that force, so fast Francesco Caracciolos offered a way to shift between the Adriatic, Ionian, and Tyrrhenian seas while also accounting for France.

Ten 14-inch guns and an Adriatic battle-fleet fist
Four Tegetthoffs and four heavier Ersatz Monarchs could have formed an eight-battleship concentration that Italy could not safely ignore in the confined Adriatic.
