Shipyard capacity during the dreadnought transition

William Beardmore's broad industrial capability included armour, guns, engines, railway locomotives, aircraft, cars, and major warships such as Agamemnon. Because Agamemnon and Lord Nelson were already overtaken by HMS Dreadnought when completed, the counterfactual asks whether their guns and yard capacity could instead have supported a two-ship dreadnought trial. Building two experimental ships would have reduced the risk of judging an important concept from a single hull. Fitting one with Parsons turbines and the other with Brown-Curtis machinery would also have made the comparison more informative while using Britain's deep shipbuilding base.
