It's not exactly realistic but about the only option you have is to open up the range to about 4000+ yards, with fog you might not even have to be that far, and put a few deck gun rounds into the TF.
Maybe you can get them to slow down and you than can maneuver into position for a decent shot. If the TF can't see you they will not return fire.
No radar so you will have to shoot off sonar bearings, don't need to hit just come close.
I've lost more than one TF because of this type situation and it's frustrating
but nothing you can do about it, you were simply not in the right place at the right time.
