I've started looking into this several weeks ago. It's one of the things I intend to experiment with once I've caught up with all my other mod projects.
As an aside, I'm working on the angle of depth charges leaving behind pockets of 'noise' after they explode. Which is what they really did. It took between 10 - 15 minutes after a DC attack for that noise to disappate and for escorts to try re-acquiring contact again. Quite often a U-boat could evade and creep away during that time.
The mod I'm working on shows a lot of promise so far with that. It's being alpha tested for now (anything dealing with AI
behavior --sensors in particular-- requires a
lot of testing) but, so far, things are looking quite good!
