The major powers allowed themselves 135,000:135,000:81,000 tons for developing aircraft carriers, a new form of warship. The Washington Conference avoided an expensive buildup by each power worrying the other two might be getting too powerful. The agreements forced the US to scrap 15 old battleships and two new ones, along with 13 ships under construction. Britain had to scrap ships too—indeed, more warships were “lost at Washington” than at any battle in history.
