I was addressing just the issue of speed. The torperdoes aren't intended against carriers really. The carrier groups are supposed to be attacked by something like submarine launched self organizing packs of antiship supersonic missiles like https://en.wikipedia.org/wiki/P-800_Oniks. An attack submarine like https://en.wikipedia.org/wiki/Yasen-class_submarine carries 32 missiles and can launch 8 per salvo (the VLS launchers are revolver type, so the delay between salvos is very short) from 100km distance in the low-altitude sea-skimming mode. Such an attack would present serious challenge to the carrier group defenses. It is basically machine against machine - automated CIWS vs. the missiles incoming at 2.5Mach (and the new generation of hypersonic missiles is coming https://en.wikipedia.org/wiki/BrahMos), and humans have no role in such engagement.
