Hydrophones and continuous maneuver help the British cruisers evade torpedoes at long range, while the Japanese ships pay for their three-knot advantage with protection. The Japanese advantage remains useful for refusing combat, but it becomes costly once they stay inside 8-inch-gun range. The discussion connects British zigzagging habits to the First World War loss of Cressy, Aboukir, and Hogue, noting that anti-submarine caution reduced speed of advance but improved survival. The T-class submarine's heavy bow salvo appears as the dangerous exception designed to exploit even a brief favorable firing geometry.

More torpedoes still do not overcome the protection tradeoff
Even after the Japanese cruisers receive more torpedoes, long-range launches struggle against maneuvering opponents and cannot compensate for reduced armour once gun combat continues.
