If a bunch of microphones and binoculars would defeat stealth fighters (or any kind of jets) don't you think someone in the US, Chinese or Russian army would have thought about it ? Just as a reminder the thing is coming at mach 1.5-2 and as soon as it can it'll send a little present coming your way at mach 2-4

> therefore it must be possible to create devices that can detect it.

What's the probability some over worked dude who tweet 20 times an hour came up with something the US military–industrial complex hasn't thought about in the last 50 years ?

Remember the early Ukraine invasion when a couple of bayraktars almost single handedly saved the country during the initial wave ? It was neither stealthy nor fast

The Bayraktars are the budget-drone option. A big part of their success was less that they're good, and more that the Russians kept all of their EW and AA turned off to achieve tactical surprise. Which they sort of did, but not enough to anchor the fight, and the budget drones were effective at killing a lot of AA early on, increasing their window of lethality.

Once they got their EW & AA game together the Bayraktars stopped being dangerous very quickly.

I highly doubt f35 will use supersonic speed for anything else than repositioning/travel. In combat theaters i doubt it speed will go higher than Mach 0.8.

And anyway, if you want CAS, to stop an army, A-10 will probably be a dozen time better suited than any multirole, and especially the f35 with its ridiculously low availability rate, or even better in that particular case, an AC-130 (that is probably able to direct a drone fleet in its latest revision, but that was speculation last time i checked)

(the A-10 is the best modern plane in my opinion, i really like the F15, f18 and Rafale (those curves!), because i really like the idea of aircraft carrier but that plane is the best.)

Ukrainians already built a microphone network to detect incoming missile and planes.
