First of all, I'm a complete newbie at modding.
I have downloaded two playable Fletcher DD's. Each has only one torp tube with one torp in it. I would like to add more tubes and reload stores.
Using S3d I found you can change wpn_SubTorpedoSys in the .sim file, but this alone does not work.
so here comes the questions
Is it possible to add the tubes and reloads?
Is this something I should even try given my lack of experience?
What other files need to be edited to add the tubes/reloads?
A step by step,( using little words

) tutorial would be nice, but I'm just looking for a point in the right direction.
Many thanks for any help!
