Well I would check to make sure, but my NF install is broken right now and trainworld.us doesn't have Soviet torpedo launchers listed.
I strongly recommend you delay-class your BO and torpedo men until level 44 or higher anyways. Additionally, you want to try to roll your torpedo men with 10 or 11 in torpedo, at least 11 in repair, and at least 10 in restore. You can even use an elite repairman if you want.
Keep them as soviet sailors (not neutral!) but don't class to BO/armament sailor. Also, remove ALL the crew from your SS BO. Class the BO at 49, and the torpedo men the same (when you're ready to start playing in subs, that is). If you aren't delay-classing, there's no point in using high-repair torpedo men: when you class to armament, they lose most of their repair growth.
The reasons can get complicated, but the short version is: your BOs stats aren't important, high level SS crews are too heavy to fit so you have to get rid of sailors, and the BO contributes the least to your ship's repair and restore. If you get stuck with any vets on your BO, it's weight that you lose forever with no benefits. By delay-classing your BO, he gets XP faster and you can level him and his crew on a bigger ship during levels 39-49, which means more XP per game and more fun (the SS1 is so, so very bad, and this way you can skip it).
Your torpedo men, on the other hand, are easy to cap on torpedo reload ability. By delay-classing, you reach the cap 10 or 15 levels later, but they have WAY more repair and restore, which is important since there's little room for actual repairmen on a sub.
That's probably not what you wanted to hear if you've already started your crew, but that's the best way to go. There's more detail in my KM SS crew guide: http://fm.en.kupaisky.com/Community/Forum/View.aspx?num=3554&category=A04 if you want to see more of the reasoning behind this stuff.
