By 1934-35, the Navy was reconsidering how quickly an old-gun fast capital ship might be fielded, an idea that later fed the studies behind HMS Vanguard. Some contemporary writers argued that Tiger should have been preserved instead of Iron Duke. Sentiment around Admiral Jellicoe's Jutland flagship was one proposed explanation for Iron Duke's survival, although the original gunnery-training choice had rational grounds. These doubts emerged within a few years as rearmament and war planning changed the value of a fast hull, so the counterfactual is grounded in contemporary debate as well as hindsight.
