Hey there KaleunMarco! If you still have some "odd" torpedoes in the bunker, or load-out when using this in FotRSU, we have discovered a date issue on some of the subs' upc files that (we hope) are corrected in the next FotRSU release. The dates listed are "backwards" for use and / or the numbering scheme of the loadout is backwards, and you would then probably find the "default" SH4 torpedo, which seems to be the G7a-TI in your USN submarine... We discovered this quite by accident when trying to find ID conflicts between Jimimadrid's Torpedoes, and FotRSU...
