The CF-109 is Costigar's most advance combat-ready fighter. It features a new canopy, an added cannon in the nose, one hardpoint for a drop tank, two hardpoints for bombs or rockets or even more drop tanks, better radio, and more advanced flaps. But, with advance comes cost, so only a few of these fighters are distributed to the aces. By the way, you get a cookie if you know what plane this was based off of.
