Shame there isn't a way to script some of the AI u-boats to disappear when they come in contact and then have one or two convoy ships explode a little later as though they have been hit by other subs.
This would be reasonably realistic, as there are lots of accounts of sub crews figuring out another sub was in the area from events such as this, and it's not as if the subs would be radioing one another and co-ordinating attacks, which tends to happen via TS in multiplayer, making it less realistic anyway.
