The problem with a GAU-8/A as a fighter gun is that the weapon and its
ammunition tank are so enormous that the plane has to be designed
around them, and they would use up a substantial part of the internal
volume of a fighter aircraft. Better to go with the Oerlikon KCA,
which fires equally powerful ammo in a much more compact package.

Well, for a fighter-only gun, versus the GAU-8, yeah. But for a
ground-attack weapon, the GAU-8 is pretty cool for air-to-air.

(Three times the firing rate, and seven times as much ammo in the plane.)
