Dead reckoning in a drone would be a nearly impossible feat considering how variable wind can be.

If you have a downward facing camera you can track your movement like an optical mouse by just watching the terrain. Error will creep in, but you only need to fly a few kilometers till you find something that looks like a strategic bomber.

I'm dumb. I don't know why I didn't think about the cameras being used to maintain location.

Hoping and praying someone in the administration is able to convince Trump to align closer to Ukraine (even if only slightly) because of this. The Ukrainians pulled off an absolute coup on Sunday. A third of a nuclear-armed country's strategic bomber fleet inoperable for the foreseeable future. Someone at NORAD probably said "they should have sent a poet" while looking at the satellite imagery. If middle powers like…

Apparently the final tally was 12 planes, but still, an impressive display

"Display" being the operative word. Good for PR, and maybe good for NATO in some small way in the future, but it won't change the war or how many Ukrainians are getting killed. A lot of the Ukrainian "wins" in this war have been of that nature, which probably isn't surprising considering they're being planned by outsiders with other motives.

> operational anti drone turret is not a thing yet. I’ve read about a bunch of these systems even if they aren’t in widespread deployment some are still being tested in real world conditions. What about: https://en.wikipedia.org/wiki/Silent_Hunter_(laser_weapon) “The Silent Hunter has been used by Saudi Arabia to guard against Houthi drones and missiles.” “During the World Defense Show in Riyadh the February 05, 2024…

Again, it takes few seconds per target with current laser tech. Which means they don't have important simultaneous multi target engagement capability. The targets, whether it's plumbing pipe rockets or lipo drones, come in at 100-1000 yards/sec, so you don't really have that many seconds per target. They work in the demo in which you just shoot down the sole target as it fly perpendicular to the machine for both phys…

The quotes suggest that system has actually been deployed and used successfully in real world conditions.

Also, your objection doesn’t really fit how drones have been used. Massive highly coordinated drone swarms are extremely unusual, the threat is mostly individual drones or small clusters.

Many very dangerous drones are well under 100y/s aka 200mph.

1000 yards/second aka Mach 2.7 is well beyond the ‘drones’ people are concerned with and into expensive missile territory. Which is where anti missile systems get used.

Israel published last week that it (trialed) deployed laser system to shoot down drones year ago at North. It had 40 intercepts or so. Full operational deployment scheduled for the end of this year

You mean the demo done recently? The article might be misleading. The IDF tested 20 different systems produced by their military OEMs. It wasn't just lasers, and lasers are far from being the clear winner. Here's the official post, it contains a demonstration video: https://www.linkedin.com/posts/israelimod_israel-mod-complet...

Other countries have hangars or bunkers to store their planes. That Russia doesn't, is really beyond comprehension.

Supposedly they had to be outside to comply with START provisions. But US keeps B-52s (and pretty much all fighters) outside. They might be under tin roofs in desert locations to keep cool. Not in bunkers.

Yeah, you can find plenty of examples of them sitting right out in the open. They're protected by two oceans, not by bunkers. A similar attack with trucks full of drones would make short work of them just as well.

> As an engineer, I am fascinated by it all. As a human, I am horrified that we democratized violence on this scale. How do you even defend against this in a terrorist use case? When a small drone with a grenade or homemade explosive is so accessible?

I mean…you can’t, at least not right now, not for civvies. Let’s consider some of the current countermeasures: * Flak/Shrapnel/Birdshot: An excellent last-minute defense if you’re calm enough to line up an accurate shot, but data shows that equipping civilians with these sorts of weapons en masse is a bad idea for safety and well-being. That’s a no-go. * Nets: Popular for defense, but it’s a matter of time before dro…

>Nets: Popular for defense, but it’s a matter of time before drones adapt by flying under the nets or changing payload to something to dissolve it.

Worth noting here that the Ukrainian armed forces have already repeatedly deployed drones with the ability to spray pretty impressive amounts of napalm all over their targets from fairly high altitudes. Fittingly, they've been called "Dragon drones", and I wouldn't want to be under any anti-drone net if one of those arrives.

Drone warfare has always been equal parts distressing (it’s impersonal, it’s too easy to leverage, and therefore too easy to abuse) and incredible (ultra-thin fiber as a kite line? Brilliant!) to me. These advances are no different. That said, I do fret we’re staring down a new age of guerrilla warfare. Drones are cheap, widely available, and increasingly autonomous. Their countermeasures are either impractical for c…

fwiw, I think the car barriers never had the purpose to stop cars, but to show people that at least on some level someone cares about their perceived safety.

This article did not even cover some of the weird solutions being deployed against drones. For example, Russia has surrounded many of their critical infrastructure sites with huge nets (similar to golf course barrier netting). They have also developed anti-drone drones that drop nets from above, catching and tangling target drones in a bunch of netting that simply snags the blades.

> They have also developed anti-drone drones that drop nets from above, catching and tangling target drones in a bunch of netting that simply snags the blades.

Yeah if we could just all agree that from now on, all warfare is limited to drone-on-drone engagements.
