You know, people are free to speculate, and everyone is entitled to their opinions. Comparing an F-105, which is a “lead sled”, to the F-35 is somewhat facetious. The F-105 would take several counties to turn around, while the F-35 is as good in a manoeuvrability range as the current F-18s and F-16s. So it's a specious argument.
Now, when you have stealth, there is compromise. You do have to compromise. You're not going to have the fastest airplane in the world or the one that can stand on its tail the longest, because to aerodynamically create stealth, you have to give something up. But it doesn't have to be the fastest airplane in the world or the absolute most manoeuvrable. That would be the F-22.
But what it does is multi-role. I can cover the air-to-air mission as well as anything out there, the point being it doesn't have to get into those close-in dogfights because that's the whole point of stealth. You deal with the adversary at long range, and they don't even know they've been taken out. But if it gets into survival and you have to fight the fight, it's still as good as anything that's out there right now. It's not the very most manoeuvrable airplane. That's the F-22. But that airplane is designed strictly for air superiority. This one is doing multi-role. That's the compromise piece that always has to be considered.
