To be sure, torpedoes in the real world have stayed the same externally for a century or more. There's a worldwide standardization to 533mm/21in caliber and counterrotating propellers that has worked very well and keeps on working. Additional "microtorps" have been introduced for ship, helicopter or coastal submarine use when the target is a submarine, but the 533mm torp remains the sole size and shape in antiship applications. Of course, the warhead no longer is TNT or even Torpex - there are advanced explosives, shaped charges, and nuclear tips. And the powerplant and guidance have changed several times, too.
There would be many advantages to standardizing the caliber like this in Star Trek, too. Why change that which works, when change would mean loss of compatibility?
