I've come up with a couple of designs for small escort ships which can fulfill a good anti-fighter role under the new rules. Each costs only roughly as much as 2-3 flights of fighters, and can potentially take out at least that many or more.
The Valkyrie is designed to rapidly close range with fighter flights and knife-fight them to death. The Multi-Missile Pod armament can put out 8 repeating, 2+ hit, no range mod, and fire-controlled shots -- plenty to cripple enemy fighter flights.
The Archer is far slower, but with 24 hexes of range, this is ok. If it can keep itself generally pointed at the enemy fighters, and use its move to maintain distance, limited arcs won't be a problem. It can only take 9 shots per turn, but this should be enough with more range to plink over.
I'll post them on the Bourbaki Basin AE later. But I thought it would be useful to point out that these ships are cheap, excellent solutions to the fighter problem discussed here.
