Oh yeah, the missions that almost everyone hates.
What you should do is avoid going to nav 1. Bear, his wingman plust two light Kilrathi fighters will be waiting there for you, and even though two light fighters don't sound like much of a chalange, Bear or Hobbes will usually give you some damage while trying to kill the kittie cats. So, go with Hobbes to the Fralthras and kill all the fighters (you should try to get them out of the AM guns range). By that time Hobbes has probably ejected. Now, go to nav 1, try to kill the light fighters quickly so they don't kill Bear and his buddy (and so those two don't have time to kill you
). And than proceed again to nav 2. You'll have two wingman that will distract the capships, and if you're lucky take out one of them.
Now, the best way to destroy the capships for me, is to target them at an extreme range, and then move slowly without using AB's (you should save some fuel for running away after you make your torp run). When you're about 4,000 klicks away release the torp and run like hell (if you see one of the AM projectiles heading towards you abort and start over).
To target a capship at an extreme range, select any missile other than torpedo (chaff also works). Lock on the capship and move away. Than when you're about 25,000 klicks away turn around. You should still be locked on the big cat. Then select a torp, and it'll start locking on, while you move towards the capships, making minor course corrections so that the Fralthras won't hit you with their guns, but make sure you don't turn to much since you could loose your lock.
