What ships and weapons have been used to kill the AC ? The canonical method is to use any ship that has two or more turrets, and four or more cannons,plus the tractor beam, and then lock onto the AC and grind him down. I have also done it in a Kestral using neutron blasters instead of the tractor beam. This is a good way if you are a Confed. I recently did it in a Rebel Cruiser (captured) with Javelin missiles instead of the tractor beam. This was the most efficient method I have used. I also did it (permit me to bragg a little) in a Lightning; 4 proton cannons, a proton turret and the tractor beam. This is touchy. What works best is to maneuver your lightning so that it is centered on top of the AC and lock on. The Alien fighters won't fire their beams at you then. I have never been able to get anywhere using missiles or torpedoes.
