  1. Addendum: "breaking" modern encryption isn't really a thing. You would need quantum computers that don't really exist at the moment, or more time than until the end of the universe to do something like that - even the dumbest CPUs that cost $1 a piece have integrated modern encryption nowadays.

    What is usually attacked is when whoever built the device, hardware or software, made a mistake or cut some corners, like not implementing encryption at all or not generating encryption key properly or messing up some code or even left a backdoor. That's where you might see a difference between Raytheon and DJI drones.

  2. Modern CPUs have dedicated hardware for encryption, so that is not really a concern unless in very very constrained environments.

    When you watch a youtube video on a phone on a tablet, that video is going through at least two layers of encryption - your device's connection to your wifi or to mobile network is encrypted, and all connections between web browser or app and Google's servers are encrypted as well.

    That doesn't mean there aren't vulnerabilities, especially if the protocol designer is kind of a dummy, like in my favorite talk here:

    Hmm, not so sure about this part (I totally agree with the rest). Military drones are in their infancy and so is EW wrt to drones.

    Devices that blast loudly to drown the spectrum are surely on the way out. But there are other ways. You could attack the transmission protocols and try to take over the drone. Or attack the video transmission to spy on the drone, or even fake it. Or put an EMP blaster on a drone and try to fry others. Or have cheaper EW emitters than the means to find and destroy them (economic attrition).

    I'm no expert in this matter, but I think it is too early to dismiss EW.

    And that's even before you get to the overlap between EW and direct energy weapons. For non-autonomous drone, short and well targeted blast can destroy receivers and render it uncontrollable without needing to broadcast in all direction all the time. Lasers can destroy cameras at way lower power levels than that are needed for vaporizing something.

    None of this means drones are defeated - but I think "we haven't seen majority of the arms race yet" is pretty safe position. It also makes me somewhat frustrated that I don't see major Western militaries investing into this, but maybe it's just classified.

  4. I think whoever is going to figure out long range cheap and precise weapons is going to rule the world, basically. Imagine Ukraine had few thousand Storm Shadows instead of like 50. The war would be probably over by now.

    Shaheds meanwhile deliver on the cheap and long range but not on the precise. Russia had a lot of missiles of various types, but they don't seem to deliver on the precise or cheap either. FPVs are cheap and precise but not long range.

    The only case where we have seen all three is with the Ukrainian naval drones - and the effect has been devastating. I don't know if the Ukrainian plane drones used for refinery hunting count as cheap and precise, but they seem to be having effect as well.

    But delivering on something cheap is kind of hard because the MIC wants its cut. So who knows where we'll end up.

  5. Big part of suicide drone autonomy is cameras and image processing, and we can make cheap cameras (in visible spectrum) and cheap chips that are pretty good at image processing. Basic communication is also easy, motors, batteries, everything is COTS and already accessible.

    Once you go into things like "every drone can see in far infrared" or "every drone has satellite uplink" or "every drone has AESA radar or similarly complex electronics so it can become anti-radiation missile" or something, that is where I can imagine things might get expensive.

    If the details on targeting using HIMARS from a year ago remain true, https://www.washingtonpost.com/world/2023/02/09/ukraine-himars-rocket-artillery-russia/

    then the statement is not useful, it really depends on whether the U.S approves the targets and whether Ukraine still follows on U.S approval these days vs a year ago.

    I think this is evolving quite a bit as time goes on.

    I remember when Ukraine first got HIMARS, US specifically modified it so it won't fire ATACMS even if Ukraine got it from somewhere else, to "prevent escalation". Now they actually have ATACMS from US.

    I'm curious if Blinken meant the statement that Ukraine can target whatever it wants now. Although "they can target whatever they want but if they hit Russia we'll stop supporting them" is still technically "they can target whatever".

    This one is still bizarre to my eyes.  Not the objectives or plan - opening up a new “front” has a lot of pluses from the Russian side, not the least of which getting the West all flustered.  It was how Russia appears to have tried this.  If the reports of this attack being done largely by dismounted infantry are in fact accurate then something is going on.  Either this was an RA tactic based on battlefield realities, or the RA does not have enough mech left to make a proper go of it…or a combination of both.  I mean conducting an operational advance with dismounted infantry is something from WW1.  I think there was this sort of action during the Iran-Iraq war but again, this is not normal.  I for one am really interested in how this all went down as it may provide some clues as to the health of the RA.

    I thought Ukraine attacked with dismounted infantry as well - except then we call it "infiltration" and "fog eating snow".

    What is the difference in how Russia does it and how Ukraine does it? There's probably some nuance I'm missing. I think in that nuance we might see some answers?

  8. Yeah, I've noticed this as well. I also saw few previously pretty neutral channels starting with the narrative "now that Ukraine is obviously defeated and Russia will take over soon, let's talk about how Russia is going to attack NATO". If you look carefully, there's always some proof of this being Russian op - I've noticed obsession with warm water ports or claming that "Russian speaking Ukrainians are actually Russians or at least would be happy with Russia taking over".

    Even if this approach didn't backfire, which it almost certainly would, we would be winning by defeating the whole point of winning. I think most people here, myself included, want Ukraine to win for Ukraine's sake. But from the West's perspective the whole point of supporting Ukraine is to uphold international law. You can't uphold international law by breaking international law. We would be "winning" by maximizing the defeat of our own political objectives, giving us an outcome even worse for us than if we had lost.

    There is no breaking of international law in not telling Ukraine "you can't use Western weapons to attack Russia". There is no breaking of international law in not telling Ukraine "stop attacking refineries". There is no breaking of international law in being asserting in protecting our airspace.

    You could see the difference when Iran launched missiles at Israel and US, UK, France and possibly others went to intercept. Is someone intercepting missiles Russia is launching at Ukraine?

    And they spread that conspiracy and many others so quite successfully. 

    And they will continue to do that, because it is intrinsic to their warfare against democracy.

    So why not become the monster your enemy paints you as? Within limits.

    Russian soldiers are already suiciding with grenades when taken prisoner because they're being told stories about the Ukrainian Gestapo prisons. 

    It is entirely necessary to use every reasonable means of warfare and subterfuge in this war that does not unravel the international order too much because your enemy will accuse you anyway and benefit from this accusation anyway.

    As long as the West found no defense against this form of warfare, offense is the only defense.

    That means sinking Russian, Iranian and North Korean freighters, claiming it must have been an accident or terrorists, and when Russia hands over the evidence of an American torpedo / USV to the UN and threatens to nuke New York (as they are already doing every week) you take a giant sh*t in the middle of the UN assembly and claim it's made up. It doesn't matter. The people who are already on the Axis side will believe what they want anyway.

    Russia will always say that it is Ukrainian sabotage or NATO spies. They already do, and plenty of people believe it.

    It is time to stop using western power to fump toxic waste in Africa and to do actually heinous **** (to your enemies) because you *can*. Because your enemy is already is doing that and the advantage of keeping the moral high ground becomes meaningless when people get massacred anyway.

    This is a well known problem is politics, called "They go low, we go high." There's a youtube video that nicely explains it in US politics context: 

    But long story short - if you have two sides fighting, and one is willing to do absolutely everything, legal or not, moral or not, monstrous or not, and the other limits itself to what is "proper", then if that "bad guy" side is able to manipulate various systems to its advantage, it will win.

    Everybody assumed that the the Russians would be the tiniest bit rational about throwing good money and lives after bad. We were wrong, we all need to take a deep breath and stay in the fight.

    The flipside of this is that the Russian are completely willing to collapse themselves by throwing more and more to its destruction. If the Ukrainians had enough ammo, drones and air defences they could turn this into a tower defence game and just wait until Russia runs out of meat and metal.

    But we can't seem to be able to supply them with enough ammo, drones and airdefenses.

    Indeed. Smarter people than me probably know why this hasn’t already been done, but Ukraine and the west need to stop saying their goal is the expulsion of Russians from all Ukrainian territory. Unless the US enters the war on Ukraine’s side that is not going to happen.

    The stated goal should be to secure a peace that minimizes loss of Ukrainian territory while providing maximum security for Ukraine post-war. In other words, Ukraine needs to end the war similar to how Finland ended the Winter War back in 1941.

    Of course, the flip side is that they’ll also need those fortifications and ongoing powerful western support to give Russia an incentive to actually stop.

    That sounds like handing Russia a win for no reason.

    If radar detection & triangulation is that easy, I'm wondering why anyone in this conflict still has a radar dish?

    Yeah. Maybe the technology just hasn't caught up yet. But anti-radiation munitions aren't exactly common. Ukraine used HARM and now mostly seems to use static targeting cruise missiles to target air defences. Same with Russia, most of the time we hear of destroyed Ukrainian AD it's Iskander or similar.

    I would totally expect Shaheds or equivalents that are programmed to go in the middle of Ukraine/Russia and target any stronger radar that's along the way, but I don't think we've seen it. In the end, I think it's a pretty advanced capability that hasn't been commodified yet.

    If you're worried about /restoring/ the status quo, then your argument kind of fails at the first hurdle, since it presupposes that any actor can somehow magically overcome this defensive primacy.

    We've seen this in Ukraine. Defensive primacy doesn't mean you get to keep all your territory if enemy is fast enough or overwhelms you in a specific place. And it also doesn't mean your enemy won't just lob missiles at your hospitals and kindergartens forever, because they can't and you can't stop them with only defensive weapons.

    edit: or you have allies that don't have your trench system and want to help them - but the enemy is already there. Or, speaking of Serbia, you want to stop ongoing genocide.

    You can't protect even yourself just by defending, much less others.

    (In a hilariously stretched connection I've had the same conversation with regards to "this is why I train muay thai and not aikido".)
