If every Predator gets a 100W wideband transmitter and SOME of them get instead of weapons the equipment necessary to process the reflections and do the calcs then the others can get that target information and blammo.
If there are 100 Predators for every F35 in the combat zone and they ALL turn on their transmitters simultaneously at some kind of interval you're never going to know which one is carrying weapons and which one is command and control. So you can't do prioritized targeting and thus you're shooting blind. Yeah you can shoot down some of them but once you're out of missiles that's it.
Do we have to worry about 3rd world countries being able to muster this kind of response? No. But there are plenty of industrialized countries that could, and they could bleed us dry one $200mm plane at a time.
When you are designing a weapons system designed to kill people, you cannot just design something 'in a hackish fashion'. No, this shit has got to work correctly all the time.
The cheapest Predator drone cost about $5M and top flight Predators and Global Hawks cost between $20M-50M. This means flying 100 of them is not reasonable. UAVs are also not autonomous and need manned pilots. Even if you were to build 100 drones, are you going to pay for 100 extra pilots, create some kind of airport that can house 100 drones, keeping them all fueled and maintained in the desert?
Kinda naive to think that you can just use SV start up philosophies in this application.

Agreed, and I stated EXACTLY that in another portion of the thread: https://news.ycombinator.com/item?id=7907637
> When you are designing a weapons system designed to kill people, you cannot just design something 'in a hackish fashion'. No, this shit has got to work correctly all the time.
No, with that part of engineering as with EVERY part of engineering: it depends. Do you want UNIT reliability or SYSTEM reliability? Does every plane have a literal 100% chance of intercepting every target it is tasked with? No, of course not. But the missiles do, you say? Again wrong. But surely SOME portion of the entire system will work ALL THE TIME! Nope, no engineer worth his salt will give you a 100% guarantee for anything as unknown as "stopping all possible threats".
Furthermore plenty of systems that are supposed to be very reliable are made up of less reliable parts. The whole Star Wars program was based on defense in depth where no one layer of system was going to stop 100% of the warheads but multiple layers acting in concert would be able to (presumably) stop them all or almost all. Hackish is fine provided that you've got substantially overlapping coverage from multiple command and control drones. No one drone has to work 100% guaranteed because even at only a 95% success rate (which is abysmal compared to the "all the time" demand you're making) with three overlapping zones gives you .05 * .05 * .05 = .0125% chance of failing. I'll take 1/8 of a chance of failure per thousand incidents as successful enough.
Again, I'm not talking about having 100 drones with 100 pilots but perhaps having 100 drones with 9 pilots for the command and control drones (one for every 10 mules) and some kind of a very rudimentary, randomized loiter algorithm for the mules.

I want to say a bunch of really snarky stuff in response. I'm an outsider to SV; I grew up in MN, went to school in FL and now I live in TX. None of these places ever get accused of being even SLIGHTLY SV-ish in nature so I don't see how I deserve that kind of comment. Ultimately though you've made a lot of assumptions that don't necessarily hold. The idea that you're going to defeat the US using the same kind of procurement and whatever that the US uses is a non-starter. You don't try and beat the US at a symmetric war but you can defeat them with an asymmetric one. We're losing how many lives and how much money in Iraq and Afghanistan right now to IEDs which are what, 10 notches below the fancy shit we have? And yet all our fancy airplanes haven't saved a single soldier from an IED that I'm aware of.
I'm not necessarily saying that you absolutely 100% can use SV philosophies in war and win, but I am saying that the notion that the way the US military does it is the ONLY way to do it isn't correct either.
Anyway, so is your strategy to fire multiple missiles at a time for each target? Assuming it's possible for UAVs to engage air targets (which they cannot right now), how many are you going to shoot off for each target, at the cost of $0.5M for each missile, just because you developed an algorithm in a 'hackish' manner?
If you gave each pilot 10 drones to control, good luck trying to execute evasive maneuvers on all of them when they come under attack.
1. Performance is linear(ish) with cost
2. The US operates at a global maximum in price/performance
I disagree with both. Performance is roughly linear with cost given a certain operational parameter envelope. Things change when you change the envelope though. Dramatically. And the idea that the US has chosen the ultimate operational parameter window which cannot be improved on under any circumstances isn't believable.
I do appreciate everyone arguing with me long enough that I could distill it so succinctly. You may still disagree with me and that's OK. But at least my crazy heretical thoughts are more easily digested now.
It's important to understand the limits of radar too; it's not like in a video game where you get this god view of the airspace around you. You are always making tradeoffs in flight about where your radar is focused, it's range, and how many targets it can track while scanning. That's why the US and it's allies rely so heavily on an AWACs system.
UCAS aircraft that can drop bombs in a contested airspace are going to cost north of $50M per copy when all is said and done, and UCAS that can do A2A combat will be double that. Once you start putting high performance jet engines in drones, the costs start to rise. Same with avionics.
Today's drones are very very simple aircraft compared to high performance fighters.
I am not suggesting that you build unmanned F-15s for the $4mm each that you can build a Predator for. That's patently ludicrous I agree with you! So no fancy engines, nor fancy avionics. Also don't bother with swarm AI, have people on the ground handling targeting. Don't develop a billion dollar solution when $50k/year (roughly) works just fine.
What I was suggesting is that you build a bunch of aerial SAM launchers. Take a Predator, put something that can receive targeting info on it, arm it with air to air missiles. Deploy many of these in the sky. Then for every 10 missile mules, you put up a single command and control Predator. It has the fancy equipment to ensure that you can actually do targeting. Then put a transmitter on all Predators which can be turned on such that you can't detect which Predator is the command and control one.
Let's suppose that you could create this fleet of 11 for $4mm * 11 + $2mm * 10 + $20mm * 1 = $84mm This is very conservative in my mind because at this point we're basically paying US prices for the gear.
Again, we're not going for the fanciest, best, most high performance stuff ever built. Use old designs, don't worry about the best survivability, don't make them too rugged and thus don't drive up the cost. We're going for The Innovator's Dilemma style worse-is-better so long as it's functional enough to mule up the ordinance.
You can now afford at least 2x of these 11 unit Predator swarms for every 1x F-35 that can be deployed. An F-35 only carries 10 air to air weapons and that's when loaded with nothing but. The odds they get both command and control Predators on every engagement is statistically slim provided you're talking about at least a few dozen engagements.
That means that just playing a numbers game you're going to shoot down the F-35s and because you've got so many damn drones in the air enjoy quite a bit of air superiority. It's not exceedingly difficult to imagine that if the sky was thick with these things that the F-35s might not get all their ordinance away before being shot at making the grinding more painful.
Could the US manage such a feat of engineering discipline and fast-track development? NOT A CHANCE!! If you're thinking that this is unrealistic based on how things work in the US you're 100% correct. But to suppose that no other industrialized country in the world could embark on such a venture and succeed? If you believe that please stop reading HN because startups could never work/win against the entrenched giants who have all the advantages.
A Predator can't fly as high as an F-35 or F-22. It can't maneuver nearly as well either. Can't fly as fast. It can't be refueled in flight, so it's range is lower than the F-35. So you'd have to hope that the missile it carried could compensate for these deficiencies. However, missiles are very finicky, and have launch parameters that help them improve their odds. The military looks at it in terms of PoK (probability of kill). So to be cheap (so you can afford to have swarms) you have to give up performance. This will affect PoK.
Next you have to have robust, un-jammable commlinks. So far, no one has those. That's going to be expensive to develop. Humans can make decisions when the comms are degraded, or non-existent. AI has a long ways to go, and AI is expensive. To remain cheap, you'll have to give that up.
With you napkin/elevator calculations, you would be trading 22 Predators for each F-35. 22 Predators is $88M, and the F-35 will eventually drop close to $100m as it reaches IOC. Still, not a bad bargain if it works.
But now, since you've gone cheap and off the shelf, you've got a slow, unmaneuverable aircraft that can't detect a target (no radar), can't communicate well with it's controllers, and can't climb very high, limiting the range of its missiles.
Then, even if you outfit this Predator swarm with an UberMissile, you'll have blown your cost equation out of the water when this swarm comes up against SAMs, or a squadron of F-16s. The swarm won't even see the F-35s due to frontal aspect stealth, and they'll be able to target the Predators and kill them like baby seals. They'll be able to engage, kill, and disengage before the low performance Predators will be able to react.
The USSR also combined this control with extremely cheap aircraft (compared to Western counterparts). The idea would be that Central Europe would become a huge kill zone with swarms of Sukhoi and MIGs overwhelming the higher tech NATO fighters. This philosophy lasted until around the 80's with the introduction of the SU-27 and MIG-29 which were comparable in performance to their Western peers. The USSR was also alarmed at how easily the Israeli's dismantled the Soviet armed Syrian AF in the Bekaa Valley in 1982. This led them to the realization that the "quantity has a quality of its own" mantra had limits.
