fatally so in actions where the Japanese Long Lance ruled.
Because of the Washington Naval Treaty of 1922, Japan upped their game on torpedoes.
Both Admirals King and Nimitz failed to appreciate the USN intelligence on Japan's torpedo warfare capabilities, and didn't bother to investigate defensive/response measures.
I wondered why so many US DDs at Guadalcanal neglected to launch torpedoes on the chance of a lucky hit, and lucky detonation, before superior IJN forces destroyed them.
One IJN Long-Lance torpedo missed its target, kept going, and going, and managed to hit a US CV cruising some 20 miles distant.
