The part that puzzled me was saying the torpedoes were obsolete, even though they were more effective than ever. The fact that it was dangerous to use them did not make them obsolete, just risky.
And there were successful torpedo strikes in late war. In Oct. 1944 TF38 swept Formosa to clear the way for accelerated landings on the Philippines. During the air battles Japanese torpedo bombers scored one hit on CA Canberra II and two hits on CL Houston. Houston very nearly sank, as the picture on this book cover shows ....
They were becoming obsolete. Obsolete weapons sometimes succeed.
By the end of the war, only three navies had any large ships, and they were allies: the UK, France, and the US. Rockets carried by allied aircraft could sink the ships of any nation that might oppose them. Dive bombers weren't completely obsolete, the Helldiver served on front line duty until replaced by the Skyraider which was originally designed as a combo dive and torpedo bomber. The Skyraider did a fair bit of dive bombing in Korea and Vietnam. But nobody needed aerial torpedoes by the time Japan's largest ships were put out of service. They did continue to be used by subs and are still carried by subs today.
By the time any possible opposition had larger ships again, guided missiles were in use. The handwriting about guided missiles was on the wall in WW II. The Germans used them some as well as the US, but they were expensive and finicky weapons in the mid-1940s. It was obvious to anyone who understood the technology to any degree that the guidance systems would be improving with time and they showed far more promise than torpedoes. Not only were they faster, but could be dropped much further from the target.
And now the Russians have supercavatating torps that travel hundreds of miles an hour for up to 300 miles ...
