Bismarck's practical performance sets the limits for the counterfactual opponent. The design retains the roughly 30-knot trial speed but rejects a range calculation that implies 20,000 kilometres at full speed, contrasting it with about 16,430 kilometres at 19 knots. Draught and beam are then adjusted around passage through the Kiel Canal. The completed ten-gun ship is an enhanced Bismarck within the scenario's altered arms race, while German infrastructure and endurance still limit what it can do.

Testing Bismarck's speed, range, and canal limits
Trial speed, realistic cruising range, and Kiel Canal dimensions keep the enhanced Bismarck within German operating constraints.
