The loss mechanism shapes the entire response: destroyer torpedoes make anti-destroyer armament and protection central to the replacement design. The first proposal is a 30-knot fast battleship protected from end to end rather than a lightly armoured battlecruiser. It performs well in the simulation, although naval constructors and staff officers would probably react conservatively to the loss of three battleships. The preferred answer is a 28-knot ship with a 14-inch belt, accepting less speed for a clearer margin of survival.
