Ace Combat 7: Skies Unknown - Finding the F/A-18F Ace "Spider"

This Ace can be found in Mission 9, Faceless Soldier, by destroying half of the white targets before destroying all radar sites, it appears near the middle of the map after doing that. It flies high, so I suggest using a long-range weapon like HVAA to shoot him down while staying safe from the missiles. Or you can go for him quickly after destroying the last radar site to disable missiles before the second phase begins.
