How likely is a triple-turret County-class cruiser if the Hawkins class had been built to a larger Australian cruiser proposal scale?
Short answerPossible, but not automatic: extra weight might be better spent on armour and a balanced F3-like cruiser layout than on triple turrets.
NotesAn enlarged Hawkins-to-County design path shows why extra displacement would not automatically mean triple turrets. Armour, balance, hull dimensions, and speed were competing demands, and four twin turrets might produce a more rounded cruiser than a lightly protected gun platform.
