What if the Washington Naval Treaty were delayed by one year?
Short answerPartly completed G3s and comparable foreign ships could survive as exceptions, forcing a different and much more contentious treaty settlement.
NotesThe likely outcome is not an unchanged treaty but bargaining over partly completed British, American, and Japanese ships. Britain might complete some G3s and convert others, while later carrier and capital-ship choices become harder to reconcile with the historical limits. Equivalent exceptions for American South Dakotas and Japanese projects would make the settlement more contentious for every signatory. The episode shows how construction timing can reshape arms-control diplomacy.
