The main problem with the F-4 was that it wasn't given a gun because it was thought that future combat would be done with missiles, and guns were no longer necessary. Unfortunately, the early generation of missiles often didn't work. However, after early losses, pilots found a way to use energy to compensate. F-4s were also clunky because they needed a second crew member.
Anyway, the arguments about whether the F-35 is superior are irrelevant. It already surpasses the capabilities of all current NATO member aircraft --proven in the regular war games. It generally kills without ever being seen. Can countermeasures be developed to "see" it sooner or better? Certainly. That has been the point of F-35 sensor development. How do we know that it can see farther than enemy aircraft? No question they are all trying. Otoh, we've been using stealth aircraft in combat since the 90s. No one else has.
What the F-35 is not is a "pilot's" plane. Strange says it looks ugly. Well, stealth depends on the plane's ability to redirect radar and other sensor signals. So, most stealth planes have funny angles. (Actually, the F-35 is one of the best looking; but, maybe that's just me). The odd angles and lack of conventionally located wing surfaces make it necessary for a computer to control flight stability. A human couldn't do it on her own. The "fly by wire" system prevents pilots from crashing. In fact, that's the primary reason F-35s "were" not as good at dogfighting. The computers limited pilot input. Without the computer limitations, the plane could maneuver in ways that would injure or kill a human. The F-35 also incorporates a big helmet that pilots don't like because they always like to swivel their heads, and maybe just because it's claustrophobic. But, that's something that will be miniaturized like everything else.
Anyway, the whole point of the F-35 program was to create a stealthy plane that could fly as fast as a fighter, carry as much ordinance as a bomber, would use the latest communications, computer and sensor tech, and be upgradable.. Not to mention, the same basic airframe would be used by all the services, some models having vertical take off and landing capabilities; others equipped with tailhooks for carrier landing, but all being supersonic. Unlike previous stealth aircraft, F-35s are built using new materials. So, yeah, the damn thing has run way over budget. It may never be what the DD intended. Otoh, imho, the individual developments will all be used and/or incorporated into future aircraft. We are definitely spending money we don't have to spend. Our F-15s, 16s, 18s, and 22s make it unnecessary.
Otoh, no one thinks the chances that we will need to develop more advanced weapons and aircraft is getting any less
. So, if ya don't think we have air superiority now. How d'ya imagine we'll be able to get it? What is better than the F-35?
