What is the use case for a more advanced fighter? Are we gonna see J-20s and F-22s dogfight each other? I guess I thought that modern fighters were basically already invisible to radar, can they get more invisible?

Trick question, stealth fighters were never completely invisible to radar, the point is to trick the guy manning the radar to think the blip showing up isn't a hostile plane. Essentially once someone figures out what your stealth fighter looks like on the radar, you no longer have a stealth fighter.

That's generally how I've heard it described to me.

sounds like a perfect opportunity for AI to look at radar and go "seagulls don't fly at 400km/h"

Sorta, that goes for the guys on the ground, but radar tracks stuff in relation to it. So if there's a plane 30km ahead of you and you're both going the same speed in the same direction, that plane in front is significantly harder to see on radar.

Again, this is how it had been described to me.

interesting, thanks I didn't know that. How does that apply to radar-guided missiles?

[–] KhanCipher@hexbear.net 3 points 1 week ago

A radar guided missile locks onto the radar signature, which we're right back to needing to know what the stealth fighter looks like on radar so that you're sure you're not firing onto something that isn't a fighter. Now we're also not really getting into the ways to defeat radar without having stealth plane stuff on your plane.

Yeah, the goal is to make it look like something else until it is too late to stop the missile from hitting the radar.

To funnel as much money as possible into defence contractors' bank accounts.

Building it to maintain parity and how to defeat one.

According to journalists who know nothing about fighter jets, this one can go to space.

The higher up you go the more air there is for your jet engine because air is in the sky
