If you haven't read this sticky thread by Ducimus then give it a minute.
It's really good and informing!

And according to that info and if it is based on real life they should realisticly have a small chance of hearing you in the situation you were in: three destroyers closing in from your port side scaning the area infront of the convoj, they are probably alerted since you sunk a carrier two hours earlier in the nearby area and you running at 200 metres around 100rpms and exposing your port side to the sonar.

Sounds realistic enough IMHO for a guy with small knowledge about ASW.

...So, here we go. How realistic is for the destroyers being able to find a Uboat at 200meters when it is moving at 2 knots? Was this possible (and not probable) at that time?
Were the depth charges so accurate?

October 1944?
GWX AI is "under-über" compared to reality that late in the war...

Consider yourself lucky!
At least you lost your boat to a Hunter Killer group - my best boat ever was lost to two Flower Class Corvettes in dec. 1944

In RL it was common practise for convoy escorts to alternate between pinging and listening with passive sensors periodically. This means they were always alert particularly late war.

In GWX and SH3 DD's only ping if they are alerted to a uboat's presence. It does not mean that they heard you but that they were alerted to your presence. Perhaps sinking the carrier they were escorting tipped them off.:hmm:

Escorts also will sit "silent" waiting for you to make a wrong move and call their friends back into the fray when they think they have something. LAtewar the sensors are fairly hard to avoid being picked up on at any depth or speed, with the exception of >300m at which point the sensors lose you.

I would have said that your experience was fairly "realistic" within the confines of what is possible to replicate in SH3. I base this comment on several years of research, talking to WWII submariners about their experiences, reading, watching both movies and documentaries on the subject of submarine warfare in WWII. Fortunately I am not old enough to have personal experience of the subject matter.

Certainly based on the testing I've been doing for the past year or so with GWX your experience is not something I would consider extraordinary, regardeless of how frustrating it is when something like that happens.
