I was looking for a way to have alot torpedos in my sub along time ago. I had given up thinking that the game just did not allow more torpedos being added.
anyhow opon tring other things with my sub, I accidently came upon the answer.
You have to use the S3d editor (search the forums if you do not know what this is) In the SIM file of the SUB, there are storage options for torpedos. I beleive they are called arrays. you just have to add them separtly by creating new arrays. and then edit the subs UPC file accrodingly. I have done 2 missions with 20 torps up front and 15 in back with no problem.
Also I am using 1.5, not sure if that might fix it also.
If you have not used s3d editor, I suggest it.
