How often are you detected by escorts or depth charged?

[HEMISENT]

Ducimus
Usually after the initial attack. I fall into the category of having really dumb escorts. I've been playing this since it first came out and I can probably count half a dozen times I was actively located and seriously dc'd in a prolonged, concentrated attack. In the concentrated attacks the dc's were pin point as Gouldjg says. Most of the times tho the escorts are not really coordinated or if they are its a half assed attempt at best.
Very rarely will I be actively located prior to an attack(unless of course I do something incredibly stupid which has happened on occasion)
