well for one. The American pilot of that machine is something like 20+ years old having already graduated the academy years ago so is arguably more skilled and experienced than most of the main cast. Remember most of the main cast are mid-tier pilots because they are after only students. Though most of this is moot, because silver gospel is a prototype machine that have gone berserk, its pilot unconscious and is moving on auto pilot fighting using its pilot's data/instinct.

also from reading a bit more of the IS novel. the reason for the IS global domination in terms of power is because of this:
Apparently the IS could move faster than ICBMs, pilot can see everything in slow motion(similar to vanquish), they not affected by G-force so no fear of black-out/red-out and a 100% optical camouflage system. So when IS was first unveiled A single IS was able to stop a war by shooting down 2437 missiles, 207 fighter jets , disable/immobilize 5 aircraft carriers and all their naval escorts and vaporized 8 spy satellites that was tracking its movement.
