Add/Change/mod torpedo loads?
 

That's my question. Is there a file where I can go to add torpedo to my boat? More specifically, I want to add torpedoes to my reserve.

I've been looking through all the subs upc files and I can't find it. Any help or is this hard-coded?

If you mean to increase the total carrying capacity of your torpedoes, the file you're after is Data\Submarine\NSS_[subyouwant].sim. In wpn_SubTorpedoSys, open Rooms, then Fore or Aft, then Storage, right-click one of the numbers in the list, and hit Add Array. That will add one torpedo to your reserve capacity. To make this work, you also need to go into the UPC file, go down into the Compartment Equipment and Weaps section, and in Stern Torpedo and Bow Torpedo, under Bunker, change the Capacity line to the new number.
