What if the Washington Naval Treaty allowed 12,000-ton cruisers with 9.2-inch guns?
Short answerNavies would probably use the full allowance and build larger cruisers with 9.2-inch batteries.
NotesA 12,000-ton allowance and 9.2-inch gun ceiling would encourage navies to build larger, more heavily armed cruisers. British County-class equivalents might carry nine 9.2-inch guns, although eight in four twin turrets is considered more likely. Their heavier armament would move them closer to the proposed idea of a true heavy cruiser. The possible consequences for battleship limits remain undeveloped.
