What if the Washington and London treaties limited ship numbers but not tonnage or guns?
Short answerNavies would maximize each allowed hull, making N3-style 18-inch battleships and still larger successors likely.
NotesA numerical cap makes each permitted hull more valuable. Without tonnage or gun limits, the Royal Navy could revive the N3 concept and its 18-inch armament. Infrastructure upgrades would then support an even larger follow-on generation. Treaty wording can redirect competition instead of suppressing it.
