Eight sloops a year could reshape the early U-boat war

At eight sloops a year, Britain might have entered the war with roughly 160 escorts already in service, halving the later Flower-corvette requirement. More ships around convoys and Scapa Flow from the opening months would reduce merchant losses and expose Germany's small initial U-boat force to greater danger. Destroying experienced crews in 1939-40 would have a cumulative effect because survivors otherwise became the nucleus that trained expanding flotillas. Continuous construction would also keep turbine firms, shipyards, crews, and junior commands active, increasing how far production could expand once war began. The counterfactual links peacetime procurement to early operations and the human infrastructure behind later force growth.
