The Japanese never did really figure out anti-submarine warfare. We and the Brits did, putting lots of scientists and engineers on the problem. ASW techniques were one of the early successes of Operations Research.

I think the casualties to the U-boat forces eventually exceeded 90% and they STILL kept going out.
