On top of that, I think the F-16 Viper and the F/A-18 Legacy Hornet deserve a remaster. For the F-16, having some 4,000 of these aircraft serving in 26 different countries in this day and age is nothing short of remarkable, seeing action both within and outside of NATO member states. Bringing it up to standard, with removable drop tanks, functional weapons, customizable hardpoint payloads and a multitude of liveries and variants to choose from would be a godsend for those who want something fresh.
As for the F/A-18 Hornet, the F/A-18 E/F Super Hornet, and the EA-18G Growler, aircraft carrier operations would unlock brand-new possibilities - I think it’s feasible to have a Nimitz-class aircraft carrier permanently anchored off the coast of Hawaii or somewhere where you can spawn in as Super Hornets and whatnot. With catapult and arrestor cable physics implemented, it’d be a PLAYGROUND.
All in all, I think there is definitely a case to implement more fighter jets and military aircraft into IF.
