You know,  I was right about the issues with the Avenger.  That turret was real vulnerable.  It had other issues too.  Over the years we corrected a lot of them.  Imaged here are some F-12B Avengers.  Amongst other things, the turret is gone after a few too many of our fighters lost them to enemy fire.  The lasers were moved back to individual bulb mounts on the forward hull.  They worked a lot better,  being harder to destroy with one lucky hit, and they could fire on multiple targets too.  I really did like the B variant a lot better than the original.
