Roger.
By hardcoded you mean that particular torpedo names are "seen" and all others are not, correct? So if I added a new fish, it would be invisible, correct?
I was kind of hoping the AI saw a particular wake effect used by steam fish so that I could add the effect to sub oil leaks

Then when you leak, the escorts might spot the slick. For all I know they already do, lol.
Thanks for your time!
