> Besides, it's not invisible despite calling it that. It's visible in the visible spectrum and hearable in the human hearing range We didn't wait Musk to know planes weren't literally invisible or silent lmao, maybe don't take your military analysis from a man child with 0 experience in the domain. They either fly high enough that you neither hear nor see them, or low/fast enough that you're dead long before you're even aware something is coming. Also we already have unmanned aircrafts, a lot of them. Internet army experts will tell you f35 are useless because they're not invisible (duh) meanwhile in eastern Europe people are getting killed by 70+ years old tanks and other ww2 era surplus

Musk can be many bad things, but he is also right in some things. Flying high might make it invisible for human observers but the idea is that it’s not invisible in that wavelength, therefore it must be possible to create devices that can detect it. Also, this is a brand new machine that is still not ready. Just write it off, liquidate any useful work that might have been done on it and go all in drones. What’s the point of insisting on a job not done when already looks obsolete?

  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 ?

    Musk: "Ah, yes, let me use microphones to listen for objects approaching at greater than the speed of sound" I mean, yeah, if you control the ground in the battlespace and have microphone arrays all over the place, sure, maybe acoustic data could be... some part of... some kind of fused sensor network. But even with perfectly smart software and shitloads of microphones over a huge radius that is going to be a very laggy and imprecise way of measuring (checks notes) objects that may be hundreds of miles away, moving nearly or above the speed of sound, using a spectrum (acoustic waves in air) that only propagates signals at the speed of sound.

    Ukrainians already built a microphone network to detect incoming missile and planes.
    - hkpack 2y ago
      Microphone network is mostly used for low speed and high noise Iranian Shahed drones which are also made from composite materials and have very low radar visibility. (For example, Moldovan military recently mentioned that they cannot detect them with their old USSR-made radars). When one is flying towards you, you hear it from few kilometres away for minutes as it has very loud petrol-powered engine. In contrast, when you hear low passing cruise missile, you will have just few seconds until it passes over you.

    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.)

  He is wrong about that with the current technology. All you have to do to see that is look at Israel vs. Iran. In a decade drone technology might be enough to do something similar to what the F35 does, but right now the F35 is still the peek of technology. There's a reason Israel ordered more of them. AI might be able to do a dogfight which is great in terms of flight envelope, but completely unnecessary in modern stealth warfare. Despite everything you heard, stealth does work. It isn't perfect but it destroyed Russia's top of the line anti-aircraft missiles in Iran without a problem. The planes are ghosts, by the time you see them it's already too late. Drones have the advantage of reduced risk to the pilot but since a human sitting at the base will have to deal with signal delay, transmission jamming and low resolution... The difference in having a pilot physically present is huge. AI is unpredictable and unreliable e.g. Iranians were able to fool a US army drone by sending it signals that made it land. Then they took it apart and reverse engineered it.

    Yet in Ukraine we see the reverse effect. Russia has some very advanced planes that are barely used. It seems to come down to this: for the same money you can buy 1 F35 or 10,000 long range drones. If you are an army with a few SAM's, what you scare you more: a single F35 coming over the hill, or a swarm of drones so large you had no hope of taking them all out?
    - invalidname 2y ago
      Russia has nothing like the F35 and Ukraine has planes too (although not as great). Once Ukraine got F16s they had an impact (even though it's a very old model). The idea of a drone swarm is science fiction at this time. First, it's not 10,000 drones. Maybe the low quality stuff Iran builds is that cheap. A good western drone will be expensive but also of far higher quality. If you try to send a drone cloud then they are easily detected and you can just shoot them down. If you send them one by one then they get detected one at a time. A few get through as we see with Israel who dealt with well over 30,000 drones/rockets over the past year... But it took them a year to launch 30,000 rockets/drones. They did very little damage. You need logistics to send them out big logistics are a big target for an F35. If you do it from far away (like sending drones from Iran) then radars have a lot of time to pick them up and shoot them down. If you do it from close by (like Lebanon) then some might get through but the F35 in the sky will destroy you very fast. Finally, they all need to fly autonomously which is flawed. You can take them down like ducks in a row. Any soldier with a smart scope can just bring down a drone. Not to mention their deep vulnerability to electronic jamming. I used to think like you as an engineer. But having spoken to people who actually know this stuff I understood the difference. Yes, there is a price disparity which is why the Israeli army has both drones and F35. Different tools for different jobs. A drone can't carry the damage and logistics an F35 can. But sending an F35 to shoot down drones is a remarkable waste of resources. That's why Israel is working on energy/laser based defense systems which will make a swarm of 10,000 drones completely useless but won't even scratch an F35.
