Sky Target has a whole different gameplay. It has more in common with After Burner, Panzer Dragoon and StarFox than with Ace Combat.
It's a on-the-rails shooter, whereas Ace Combat and Wing Arms are dogfighting-based shooters, where you can fly wherever you want in the map, and need to pursue enemies and stuff.
Now I recall another game: Darklight Conflict. I never got my hands in the Saturn version (I heard the graphics are impressive), but it plays the same way: thrust the ship, turn around enemies, get in their tails, shot them, move onto next.
