Stealth is less effective against long range radar, stealth is more effective closer in against targeting radars.

When you're high up you can have pretty long 'line of sight' so it's not unreasonable that these could fly way way ahead. 100 miles and way more is not unreasonable.

You basically get 'double standoff'.

I can see this as being almost as effective as manned stealth and if they are cost effective they could very plausibly defeat f22 scenarios.

Once you add in the fact that risk is completely different (no human), then payload, manoeuvrability, g-force recovery safety, all that goes out the window and you have something very crazy.

3 typhoons with 2-3 'suicidal AI wingmen' each way out ahead is going to dust them up pretty good at minimum. It's really hard to say for sure obviously it depends on all the other context as well.
