What if the battleships and battlecruisers canceled due to the Washington Naval Treaty had been completed as planned? How would France and Italy respond and how would the Cherry Trees fare in the 1930s and later? Also, is there any chance the Lexington class battlecruisers could or would be retrofitted with survivability improvements? The armor protection is essentially the same as first generation Royal Navy battlecruisers but with stronger turret and barbette armor.
