What wartime dockyard expansion might have changed

The Royal Navy already contemplated dockyard upgrades for 1916 and had discussed larger graving docks, building ways, and floating dry docks with yards. Starting that work in 1914 would have made labour easier to secure before mass conscription absorbed manpower. In this counterfactual, the extra capacity could have permitted all eight planned Revenge-class battleships to be completed, although Renown and Repulse might then have remained battleships rather than becoming battlecruisers. Purpose-built battlecruisers could instead have emerged as three or four Admiral-class ships, showing how infrastructure decisions can redirect an entire generation of warship design.
