Did the Royal Navy try to retain the Iron Duke class under the Washington Naval Treaty?
Short answerNo; their 13.5-inch armament no longer justified priority unless retention could be traded for more new construction.
NotesThe Iron Dukes were still regarded as good ships, but their 13.5-inch armament no longer represented the direction of capital-ship development. Retaining them therefore offered little attraction by itself. Their bargaining value would chiefly lie in helping Britain secure additional new capital ships. A speculative preferred outcome is two Nelson-class battleships and two F3 designs.
