It seems WWI and inter-war ship designers went a bit torpedo mad, both in their fear of them and in their use, finally coming to their senses in the harsh realities of WWII. I've seen many examples of capital ships using extensive space and machinery to mount multiple torpedo tubes. Given the long range of their guns (20,000m and up) compared to the short range of the torpedo (an optimistic 5,000m), this doesn't seem to make sense.
Did a torpedo fired from a capital ship (which I'm defining as a heavy cruiser, battlecruiser or battleship) ever hit anything? How many were ever fired in anger? Was it all just a costly boondoggle?
Some examples actually built...
