Actually it does not, I use acoustic torps in 44-45 and those thing home in whatever make the loudist noise be it a DD or merchant.If your target reduces speed and so does every one else it will seek the loudist noise and chase it sometimes you might get lucky and it will hit a ship on the far side and the escorts will go looking for you on that side sometimes you might fire a a merchant might bring up speed and it will go for that ship the escorts can't detect torps being fired (as far as I know) but they will search an area of around 4000m from the ship being hit. and with a lost detection time of 45 mins they find you your screwed.(gwx)
