Dazzle camouflage doesn't work on killer drones. Even civilian LLMs recognize that the object on the photograph is a military truck, except they can't explain why it's been painted to resemble a zebra. Most dedicated machine vision models easily lock in on a boxy shape moving along a road. If anything, the stripes make the trucks easier to see.
The real answer to killer drones is a CIWS that can cover 2pi steradians and attack multiple drones at the same time, because otherwise it will be just swarmed by drones that quietly glide towards it, engines off, from several directions before entering the final dive.
Until drones deploy counter-blinkenlights. As someone who has built a realtime people tracker art installation in a disco: Stroboscopes are highly effective at confusing these models.
A military system is being launched at an area to destroy a target that is presumed to be trying to hide (hence AI).
Absolutely nothing stops a secondary, much simpler identifier system of "home on bright flickering lights".
Any system where you try to confuse an image recognition model by loudly doing something unexpected suffers from the fact that regular tracking systems have been good at finding those for a long time.
No AI model confusion tech is worthwhile if it otherwise makes something much more visible by other means - it's a scifi trope that people want something "obvious" to be invisible to the machine. It's not how reality works though.
There's a limit to the number of targeting systems you can afford to deploy on a weapon, and there's the problem of reconciling their signals if their views of where the target is start to diverge.
"Counter-blinkenlights" are well-known as thermal flares, and more similar but as crude, [dazzlers] that blind the incoming rockets' sensors.
AFAIU, a dazzler is intended to blind the whole sensor, so home on dazzler would need specialized hardware, not only a software adjustment. (Replying to other messages in this thread)
But it's not a separate system, it's just a separate algorithm - it's software.
"No target" by AI but "target" by the "engage light sources" recognizer is still successful targeting.
"No target" versus "aim at anything not green or blue" is as well.
It's also a question of the speeds involved: a dazzler on high speed jet versus a high speed missile might cause a near miss which means hundreds of meters of actual separation. Diving drone vs. truck? Not so much.
Ya, things always evolve, and can't always be perfect, especially against adapting enemies. Strobes; ya - would be interesting to see what these do vs us, not tried.
A CIWS can only fire at one direction at a time, so 2+1 drones has an extremely high chance of taking it out for around $2500 or less. CIWS is multiple magnitudes more expensive.
Modern dedicated AA gun systems claim multi-km engagement ranges against small drones, and 60 degree/second slew rates. A drone capable of beating that engagement time would be better described as a guided missile, and will certainly not cost $2500. The flaws in gun systems are in the cost required for good coverage, not their effectiveness against targets that do enter their engagement ranges.
We're moving into the "waves of drones with orchestration" phase and expensive directional systems won't survive that, and cost on the drone swarms is still drastically lower. Won't matter if you added ten ciws and ten fire-finding radars.
You're thinking on a ship, which is great, but these need to be able to provide front line coverage where I becomes an expensive target for cheap munitions. It is not a great solution. It's a fine layer against other threat classes.
Terrain clutter quickly becomes a problem on the battlefield.
CIWS might be effective against fixed wing since they fly mostly in straight lines, it won’t work effectively against multirotors that can quickly change direction and maneuver around, now add swarm of them, and it will overwhelm CIWS. That of course, assuming it was detected which is a whole process by itself.
You’re talking about dodging bullets or shrapnel here. Source on that a multi rotor has that level of manoeuvrability while also carrying a lethal payload and enough battery for a viable engagement range?
Pre-programmed evasion. Give the drone a flight path, it's expected to position itself randomly within a certain distance of that flight path. At longer ranges it's feasible to dodge a bullet that way (which is why soldiers do a highly evasive path against a sniper) and even at short ranges if you can beat the tracking system it doesn't matter if you can beat the bullet.
That’s not the problem. These machines only have so much thrust, and are only aerodynamic in one direction. Sudden high-speed lateral acceleration is very costly from an energy budget perspective. Randomly dodging around bleeds off speed and may actually reduce survivability by increasing the time taken to cross the danger zone. This is made worse by most of the time the drone needs to aim for a weak spot or critical system to do damage, so terminal guidance is already fairly constrained. You don’t see drone pilots trying to jink around because the best move is to punch the accelerator and try to minimise the time your opponent has to react.
/r/CombatFootage will show that even with strong explosive payloads the modern quads used by Ukraine are surprisingly mobile. They’re incredibly quick and manoeuvrable still, much to my surprise.
I do not actually suggest watching those videos, they are NSFL.
There’s a pretty big gulf between “very quick” and “capable of dodging air bursting autocannon rounds without sacrificing forward momentum”.
Incidentally, modern drone footage is actually not nearly as bad as stuff from earlier in the war. Increased lethality of the FPVs means much fewer conscripts deciding to take a 5.45mm retirement plan.
Right. There is no way a drone can dodge a stream of bullets. They essentially arrive instantaneously at the drone from its perspective. A bullet from these flies at 1km/s and there are a lot of bullets. The bigger problem is getting a good lock on the drone but if you can track it any AA cannon will turn it into mashed drone.
I can’t quantify the “viable engagement range” you had, but in our tests we had around 50min endurance, around 35lb payload, and 14in body but with larger props. Now larger props do impact prop acceleration to a degree, so it’s not “racing” level maneuverability, but good enough to dodge shotgun shots, and again, this is all with the presumption that you know where it is and from where it’s coming and heading.
Given that the drone is going on a one way trip, I imagine you'd want to use the cheapest hardware possible which would mean using the dumbest model you can get away with.
Depends on the value of the target. Costs Ukraine $918 to kill a Russian soldier[1] but if you’re using a fully offline automated swarm to destroy a petro system worth billions then what’s a few GPUs strapped to each one to run local models.
Your drone needs to be cheaper than what you're killing, so if your target profile is 50k+ USD and up, a $10000 even is fine (not that it would need to be even 10k).
Your oversimplification bakes in too many assumptions.
The relative financial cost to the enemy is almost irrelevant if they are much wealthier than you are.
What matters most is the intangible military value of the item.
In too many situations people think simplistically about dollars, when what matters is invisible or intangible values. The hyperfocus on money is especially egregious among people that don't have much.
That's obviously not the only metric. The cheaper the drones are, and the less resources they need the more of them you can produce as a result. This is why cheaper weapons that can be produced at scale tend to be most effective.
Which is total overkill for the job. It very well might cost more to fire a Phalanx at the drone than the value of the drone. And the Phalanx has IIRC 20 seconds of fire before it needs extensive downtime for reloading.
They need something in the realm of a big automatic shotgun.
Depends on the target, some large ISR drones totally need big 20mm rounds but you scale the system down to machine guns and shotguns and build out integrated air defence systems with electronic actively scanning radar and sensors to detect and track the threats to kill
The way the US military works, throwing rolls of toilet paper at the drone from the deck of the shop is likely more expensive than the drone said toilet paper is hurling towards.
