What if the postwar Royal Navy received the combined modern naval budgets of 2015-2022?
Short answerIt would produce a comprehensively rebuilt fleet and likely a major shipbuilding-led economic boom.
NotesThe money acts as an industrial policy shock as well as funding a larger ship order. Combining seven modern naval budgets would make comprehensive postwar fleet reconstruction financially possible. Shipyard activity would spread demand through suppliers, construction labor, and the industries supporting new warships. The counterfactual produces a rebuilt Royal Navy and a broader British economic boom driven by the scale of the work.
