There were several historical cases where a sub was sunk by another sub. Around 20 Uboats where sunk by allies subs. in all but one case- the victim was running on the surface when attacked.
The one instance Jimubna mentions - where HMS Ventura nailed U-864 while they were both submerged - was down to guess work, probability, and mathmatical genius..... oh and luck lol.
You can watch the Time Watch Documentary on youtube (in 5 parts)
