Even if they're in perfect condition, on even as low as Normal difficulty, they just get shredded by turret fire from the very corvettes they're supposed to kill. Often, they don't even manage to make a dent. They just die, leaving the player and his one wingman to kill two capships with absolutely no anti-capship weapons... and then the mission continues.
I suspect the problem lies in their torpedoes--even though the tech room says that "even laser turrets can't shoot it down," laser turrets do shoot Lances down, consistently, at any range beyond 4-5 clicks. But that only works for the player--not AI wingmen whose idea of a bombing run is flying in a straight line through 15 clicks of enemy fire.
What do?
