How triple turrets could lead to a faster Queen Elizabeth

In this design counterfactual, triple fifteen-inch turrets would require a broader Queen Elizabeth hull. Preserving the length-to-beam ratio would lengthen the ship and create more room for boilers. That extra machinery space could support roughly twenty-eight knots even with traditional boilers. Small-tube boilers would be another likely change once the design departed so far from the practice of limiting changes between successive classes.
