I had a conversation with a friend the other day, and he insisted that torpedo in modern US subs still have wires on them, so they can be hand guided if necessary.

Then it came to me why would someone want to have the unnecessary medium of like 5000 yards of cable when signals (waves) travel uderwater very quickly and you can still guide the torpedo with radiowaves or lasers.

So here's my question:

Do modern (or new if there are still any made) US subs equip with wire guided torpedos, and what's the reason for this?

Thanks!
