Get the F15s and F35s up and we'll see. Upgrading the F-15 with engines and a radar/IRS&T/AAM package of the same generation as that of the F35 would almost equalise almost all advantages the F35 has except stealth.
One key difference. F-15 has to see and point at the F-35 to acquire a missile lock. On a stealth plane, this is no easy task. The F-35 can target multiple planes simultaneously without pointing at rhe aircraft, or even being in the area. A different F-35 can acquire the targets while the wingman targets and fires. That’s a trick no one else can match. What one aircraft sees, they all see.
Yeah, lets upgrade the mach 2.2 F-15 with the engine from the mach 1.6 F-35.
