-brrt- Drone swarm, what drone swarm? https://www.youtube.com/watch?v=pb5_F4_Eod8 https://www.youtube.com/watch?v=pb5_F4_Eod8 And this is simply the first iteration of such systems.
Drones are slow (slower than WW2 aircraft), short ranged, and not particularly stealthy. Improving any of those aspects raises the price significantly, defeating the point of cheap drones. They are a threat but not as magical as some seem to imagine.
- rcme 3y agoBut they’re so cheap that you can overrun your opponents defense. Who cares if they’re slow? You can shoot down any individual drone, but you can’t shoot them all down.
- ThrowawayR2 3y agoCheaper than a bullet? Seems unlikely. And if the attacker's drone swarm is that implausibly cheap, then the defender just puts up their own implausibly cheap defensive drone swarm to counter them. Checkmate.
- rcme 3y agoHow can you take down a drone with a single bullet? It’s not trivially easy to shoot them down. Also, a “defensive” drone swarm would need more advanced tracking and targeting capabilities, so it would be more expensive. Look at Israel’s Iron Dome. A single interception costs $100,000-$150,000. The rockets being intercepted cost less than $1,000. If Israel was more evenly matched, it would be cost prohibitive to intercept all of the rockets.

Drones are slow so they can use VT rounds instead of the CIWS spray-and-track method. https://eos-aus.com/defence/counter-drone-systems/slinger/ https://eos-aus.com/defence/counter-drone-systems/slinger/
- ThrowawayR2 3y agoIt's interesting to dig deeper into the vague mention of "special ammunition". According to [1], the Slinger uses Northup Grumman's M230LF Bushmaster 30mm cannon and [2] suggests that the anti-drone ammunition is the recently developed XM1211 HEP (High Explosive Proximity) round which was designed for the M230LF. Finding about the creation of XM1211 rounds is stunning because it means that an effective radar proximity fuse is being stuffed into a tiny 30 mm diameter projectile with enough room left over for adequate explosive to generate a cloud of shrapnel. That's stuff that would have been considered sci-fi a few decades ago.

Their biggest problem is that they are trivially jammable (which will be overcome via autonomy) and operational range (which is doubled for suicide drones). Drones are about to change operational doctrine in all areas in the same way that aircraft carriers obsoleted battleships. Any military that fails to adapt to this new reality will be absolutely destroyed in the field. Defenses against overwhelming autonomous drone swarms are possible, but not via current missile defense platforms.
- ThrowawayR2 3y agoI literally posted a video from Rheinmetall demonstrating their drone defense system shooting down a group of drones using a single burst from an AA gun and they are hardly the only corporation in the defense industry working on such systems. You're welcome to contact them to insist that that's not possible and that their system will never work, if you like. The idea that 200 mph drones cannot be shot down when 300 mph WW2 aircraft can be shot down by WW2 era technology (flak does not care what size the target is) or that drones cannot be detected by radar (even flying birds can be detected by radar) merits a similar dismissal.
- kibwen 3y agoThe friendly infantry that you're trying to protect are going to love having friendly flak shells exploding fifteen feet above their lines, to say nothing of the fact that drones are so maneuverable that swarms will attack from every reachable direction simultaneously. Flak shells will be minimally useful (and ultimately more expensive than the drones that do get shot down; you've already lost economically). And "radar can detect birds, so it can detect drones" means nothing whatsoever unless you're willing to waste all your AA ammo depopulating the pigeon population. Again, nobody is saying there's no defense, but autonomous drone swarms are going to be as important to warfare as the airplane (which, likewise, there are defenses against). The important thing is to have planners acknowledge it.
