In the real ocean enviroment, even modern active sonar only has a 10% chance of detecting a sunken ship/sub sitting on the bottom. I would bet that from 39-45 its chance of detecting a sub on the bottom was almost zero. From everything I've ever read about US and German subs sitting on the bottom the largest success was when the DD's didnt know the sub was there in the first place. From what I read they were almost never detected. Its different when the sub was detected in a "certain area" and suddenly disappears, the DD's are figuring that the sub is down there somewhere sitting on the bottom so they (I would too) carpet the bottom to see if they get a lucky kill. So sitting on the bottom becomes a disaster because you are a sitting duck especially in this sim where sitting on the bottom you dont disappear as you should. I know that some will think that active sonar will be able to see a sub sitting on the bottom, and I am sure that there are certain rare instances where it could. However I base my comments on having lenngthy discussions with todays Sonar techs (my shipmates) regarding the possibility vs probability of this tactic working. We also have had excercises where there were known ship wrecks and they did not present themselves when pinged with active sonar. In some cases i thought that due to our depth and the angle the active was transmitted that it would show the wrecks sort of like a side search sonar, but was enlightened that that type of sonar that could see such detail was not operating on the same or even similar frequency as warship active sonar. So in closing I wish they did model it, and really hope SHIV does.
