Armor piercing bombs and regular torpedoes (in 1944 the USN only had "regular torpedoes" for naval aviation; ASW torpedoes would be a number of years off still, well after the war, as they'd only be practical once they'd have their own homing capability). The planes that sank Musashi were from the fleet carriers, not the Taffy CVE fleets that dealt with the more northern force.The Chinese have a missile called YJ-12 that has a warhead that weighs the same as many complete battleship shells of the era and can fly at speculated speeds up to Mach 4. If you say that that is not designed to combat battleship designs, you severely over-appreciate battleship protection schemes.But let's cut to the chase here since your responses so far have been "but this and that" and just throwing up another point for deflection, and once that point has been deflected you put up another one (not unlike an AEGIS system, actually). You've got predefined notions, you seem to be looking mostly for confirmation bias, and you have a severe lack of really appreciating what's going on here.For the third time now -. Go tomuseum, preferably a tech museum, and look at the artifacts they have from 70 years ago and compare to today. Or hell with it,since you'd greatly benefit from the experience. A failure to appreciate the basic concept of history and the passage of time and what happens in between doesn't deserve to have one's questions answered, or at least it'll mean people will no longer take this thread seriously and will just ignore it.
