Just the standard the first one you recieve.
I've added also this one now "Stock torpedoes (modified for torpedoes failure patches)" in JGSME
The last game I played they were going straight again.. but now they passing by the ships so I had to set them to 1 meter instead of 3(standard)
I hit 1 polish destroyer but the merchant ships in Danzig the torpedo dont explode on it but just hits and then turns a bit. Not sure if too close or bug.. well anyway, I went surface to try it with the deck gun but the door never opened so I couldnt stand in the tower .. sigh..
I think I should recheck TDW patcher right now I have the same things as the example screenshot of this topic
