    From Rafael’s site: https://www.rafael.co.il/system/iron-beam/

    100kW laser is nothing to joke about, but seems a good application for anti drone tasks. Fiber lasers are pretty snazzy.

      It's quiet the power requirement. I wonder how long it has to focus on a drone to eliminate it. Like how long is this thing consuming 100kW?
      • JumpCrisscross 53 minutes ago
        Huh, to what degree is this technology gatekept by battery advances?

        A few decades ago lasers were dismissed because they involved chemical reagents for high power and explosive capacitors for even low-power applications.

          > Huh, to what degree is this technology gatekept by battery advances?

          Not too much. The power delivery was doable even 15 years ago. It would have just been more expensive and heavier.

          The bigger issue I believe would have been the lens and tracking capabilities. For the tracking to work you need some pretty good cameras, pretty fast computers, and pretty good object recognition. We are talking about using high speed cameras and doing object detection each frame

      • cenamus 1 hour ago
        Good question, probably depends a lot on how much energy actually makes it to the target some distance away. And then how much is actually absorbed. Probably depends more on the power density then, rather than total power?

        Can't imagine they get a very small spot at multiple km unless they use gigantic lenses or multiple independent laser focused on the same spot

        • condensedcrab 1 hour ago
          Even small divergence angles add up if they’re trying to intercept at visual ranges outside of traditional munitions.

          That being said, probably ~10kW/m^2 is enough to overheat or disable a UAV

        • JumpCrisscross 1 hour ago
          Maybe it involves multiple converging beams to reduce transmission losses?
      • jstummbillig 1 hour ago
        Hm, you think longer than the laser is firing? Could there be windup?
        • cogman10 1 hour ago
          I imagine there's some sort of storage system, like a huge bank of ultra-capacitors, that are constantly kept charged.

          The wind up would be if that bank is depleted and they need to recharge. Delivering 100kW for a short period of time is definitely a feat.

    Personally I think that defensive technology like this is fantastic. It means that innocent citizens will be protected from constant bombardment or thread of bombardment by cheap mass produced rockets or drones. Israeli civilians have faced bombardment by tens of thousands of rockets from Gaza for the last 20 years [1].

    Outside the Middle East there's many areas threatened by combatants with similar cheap missiles. Perhaps Ukraine is an obvious one. We're seeing rises in conflicts across parts of Africa, Cambodia/Thailand, Pakistan/India. Many governments are looking into buying these to protect their countries.

    This technology hopefully can protect populations from destabilizing forces funded on the cheap by foreign powers. Machine guns changed warfare [2] and drones have been a similar massive change in warfare making it cheaper and easier to attack and destabalize regions. Though of course there's downsides as well [3].

      One could also hope that e.g. Iran starts focusing its economy on the wellbeing of its people versus playing regional cop to America’s world police.

      Three thoughts:

      1. Just to repeat myself from another comment on this thread, there is no such thing as a defensive weapon. Were it not for the various missile shields, the Israeli state wouldn't act with wanton abandon against its own citizens and its neighbours. All of the various war crimes and terror attacks are a direct consequence of the effectiveness of a "defensive" missile shield.

      Let me pose this question to you: if these were purely defensive technologies, why don't we give them to everyone, including the Palestinians? and

      2. Israel has already ruled out giving Ukraine the anti-missile (and assumedly anti-drone) defenses [1]; and

      3. Many people, yourself included it seems, need to examine these conflicts around the world through the lens of historical materialism.

      Take the genocide and conflict in Sudan. The SAF are arguably the ones with the "cheap rockets" here. Should we be giving the RSF anti-drone technology? The RSF are backed by the UAE using US weapons. Why? To loot Sudanese gold.

      Why did Russia invade Ukraine? Territory, access to the Black Sea, resources and to create a land bridge to Crimea that had otherwise become extremely expensive to maintain as a colonial outpost. Like, just look at a map of controlled territory.

      But why is it in a stalemate? In part because Russia is a nuclear power but also because the West is unwilling to let Ukraine do the one thing it could do to defend itself properly and that is to attack Russian energy infrastructure. Despite the sanctions, Russia is still allowed to sell oil and gas to places like Hungary, Slovakia, France, Belgium, India and China.

      Back to the Middle East, we have Yemen, who was devastated by war and genocide at the hands of another US ally, Saudi Arabia.

      The solution to these conflicts isn't more weapons, not even "defensive weapons". It's solving the underlying economic conditions that created that conflict in the first place.

        There is no such thing as a defensive weapon.

        You might be tempted to say "what about a missile shield?" but such a thing allows the owner to act with impunity with levels of violence we arguably haven't seen since 1945.

        As a real example of this, the only reason a deeper conflict didn't develop with Iran this year was because Iran demonstrated they could overwhelm the various layers of Israel's missile shield and Iran seriously depleted the various munitions used by those air defense systems (eg interceptors, THAAD) and those take a long time to replenish.

          > You might be tempted to say "what about a missile shield?" but such a thing allows the owner to act with impunity with levels of violence we arguably haven't seen since 1945.

          I would still say "what about a missile shield?".

          If a missile shield is a weapon, because of its affordances, then any object is a weapon. And while that's marginally true I don't think we get anywhere by entertaining category errors.

          If something enables aggression, because it makes counter attacks unreasonable, that seems like a fairly nice thing to have more of, in a world where destruction is far too easy and construction is fairly hard.

        • JumpCrisscross 1 hour ago
          > There is no such thing as a defensive weapon

          I agree if we reframe it as “purely defensive,” though there is a bit of tautology invoked with the “weapon” qualifier.

          That said, there is legitimacy to developing defensive arms, even if one doesn’t like the ones doing it.

          > the only reason a deeper conflict didn't develop with Iran this year was because Iran demonstrated they could overwhelm the various layers of Israel's missile shield

          This hypothesis is not sustained by Iran’s reduced firing rate throughout the conflict. All evidence suggests Iran lost its war with Israel and would lose it again if they go for round 2.

          "Act with impunity" in case of Israel is basically just existing
      • cogman10 1 hour ago
        Could definitely be used in an offensive capacity. I don't think it'll be a red alert 2 style prism cannon, but I do think it can be used to gain air superiority. With a long enough runtime, this thing could definitely take out a plane.

        That said, it's pretty tame. We can already take out planes with flak cannons. This is just more efficient.

    Israel saw over 16,000 rocket attacks last year from fundamentalist groups like Hamas, Hezbollah, Iran, and Yemen. The Iron Dome intercepted ~90% of them, resulting in thousands of lives saved.

    Iron Beam is the newer incarnation of this technology that uses lasers to intercept incoming rockets and drones with precision and much lower cost. Wonderful technology.

    • RegnisGnaw 1 hour ago
      Lets send some over to Ukraine.
    • elcritch 1 hour ago
      Each Iron Dome interception cost many times more than the cost of the rockets. This will make it cheaper for other poorer nations to afford and operate.

    A lot of comments decrying new weapons tech, but I think drone defense tech is particularly critical right now and going to save a lot of lives. Put another way, I don't think we would be against new clothing that made bullets less effective, even if it remains terrible that such clothing is needed.

    Especially as AI becomes better and cheaper and suicide drones become more nimble and autonomous. If you have seen any of the horrifying footage out of Ukraine you will understand how badly we need more effective and cheaper drone defense as soon as possible.

    • cogman10 1 hour ago
      Yeah, I see this as ultimately a wash.

      In Russia/Ukraine, drones have proven to be a very real threat to deal with (arguably also in Iraq).

      What this means is wealthy nations will snatch up or recreate this and deploy it. That will stop smaller resistance forces from either defending or attacking. Depending on the nation in question this could both good or bad. Just like drones, guns, or tanks.

      Effectively, this puts the status quo back to where it was before mass drone deployments.

      • causal 59 minutes ago
        Which, IMO, is better than having swarms of cheap bombs flying around.

        Taken to the extreme, I also prefer the current status quo vs. everyone having a nuclear-tipped ICBM, and would welcome a countermeasure if cheap ICBMs became a thing.

    It is so sad the Humanity needs to develop weapons...
    • geertj 1 hour ago
      On the last day of the year, I am taking a few minutes to linger on this. At face value, most would agree with this, myself included. But I think we can dive one layer deeper. There are different schools of thoughts whether mankind is inherently good or evil. Over the years, I have become pretty firm believer that every person has the innate capacity for both good and evil, and the outcome is determined by both character and circumstances. Solzhenitsyn famously wrote (quote by Gemini):

      "The line separating good and evil passes not through states, nor between classes, nor between political parties either—but right through every human heart—and through all human hearts. This line shifts. Inside us, it oscillates with the years. And even within hearts overwhelmed by evil, one small bridgehead of good is retained. And even in the best of all hearts, there remains … an unuprooted small corner of evil."

      If you subscribe to this, then a weapons system can also be a force for good, if used by an entity for the purpose of "peace through strength". The strength keeps our innate capability for evil in check, as the consequences for evil would be guaranteed. A case in point is the MAD doctrine for nuclear weapons which has prevented a world war for the last 80 years.

      I'd appreciate philosophical replies. Am I wrong, either in a detail or at the core of the argument? Are there additional layers? I would like to kindly ask to keep replies away from views on the specific players in this specific press release. We'd just be reiterating our positions without convincing anyone.

      (edit: grammar, slight rewording)

      • yonisto 49 minutes ago
        I totally understand the need for weapons. It is just makes me sad.

        And I think Solzhenitsyn is wrong. There are psychopathic people that have no good in their hearts. Sure, with the right upbringing that could be kind and good but at a given moment they are what they are... psychopaths.

        Please read about the history of the region. This seems to be a good unbiased source, which is hard tobfind these days: https://www.theguardian.com/world/2023/nov/09/why-israel-pal...

        In particular, put attention to this:

        """ What happened to the Palestinians who were living there?

        About 700,000 Palestinians were expelled or fled – about 85% of the Arab population of the territory captured by Israel – and were never allowed to return. Palestinians called the exodus and eradication of much of their society inside Israel the Nakba, or “catastrophe”, and it remains the traumatic event at the heart of their modern history.

        Arabs who remained in Israel as citizens were subject to official discrimination. They were placed under military rule for nearly two decades, which deprived them of many basic civil rights. Much of their land was expropriated and Arab Israeli communities were deliberately kept poor and underfunded. """

          “How did the occupied Palestinian territories become occupied? In 1967 Israel launched what it said was a pre-emptive defensive war against Jordan, Egypt and Syria, as they appeared to be preparing to invaded.”

          The problem with these summaries is everyone can always somewhat legitimately claim a prior offence. The 1967 offense resulted from the shitshow that was the 1948 war [1], which itself resulted from a history of French, British and Ottoman control.

              They both suck and they both have legitimate grievances.

              They’re also both proxies on like four major axes (Iran vs Saudi Arabia, America vs Russia, America vs China and whatever Turkey is up to) and more minor axes than I’ve seen anyone even bother keeping track of.

              It’s a deep and deeply fucked conflict that doesn’t lend well to armchair border drawing from an ocean away from first principles.

              I’m sympathetic to the argument that there should be reparations—from Israel but also France, Britain and Turkey—for victims of the Nakbah.

              But let’s be clear on a right of return: this logic applies to almost every human in Europe or Asia when it comes to the Middle East if we go back far enough. We’re talking about the closest coast to the cradle of civilisation.

                You don't have to go 'back' to find Palestinians alive, today, who can point at their settler-occupied homes on a map, and tell you the day they were kicked out. I think that's a reasonable cutoff point for right of return.

      • EGreg 1 hour ago
        Just recently, US has worked with Saudis and Ukrainians and others to supply heavy and novel weaponry to be deployed in eg Yemen, coordinating airstrikes, giving intel etc. to devastating effect and has done even more direct involvement in brutal wars, whether proxy wars of whatever. The PATRIOT act and subsequent militarization of police at home supports the GP’s statement about a boomerang. I don’t think GP meant to say it was only due to Israel or single out Israel as a source US of military cooperation and MIC job creation.

        But yes, some people will only care if they can find Jewish connections, eg Zelensky being partly Jewish or MBS or Al Sisi allegedly being partly Jewish due to their stances in opposition to Islamic extremism.

        There are people who blame influential Jews for everything, and they’ll go so far as to say that Ataturk was Jewish, in order to care about the Armenian genocide. But they won’t care about, say, the Hamidian massacres of Armenians, Assyrians and Greeks that took place 20 years earlier because they can’t find any evidence that Sultan Hamid was Jewish.

        They blame Israel for Iraqi expulsion of Jews, until they find out the Farhud was 10 years before Israel was formed as a state.

        They even finally started to care about what’s happening in Sudan when they realized they can sort of draw a tenuous line between that and Israel through UAE.

        As long as influential Jews are involved they will deeply care about a conflict, eg 9/11 dancing Israelis or clean break memo of PNAC. They will ignore that presidents like W Bush called the Iraq invasion a “crusade” to “rid the world of evildoers”. They also do not like to go back further to, say, bombing of Laos and all throughout southeast Asia because, again, it is hard to blame any Jews for that.

        It’s almost as if they have an algorithm: 1) find Jews involved with thing they consider bad, 2) care about that issue but ONLY to the extent they can point out Jewish connections 3) cherrypick and compile lists of Jewish involvement to make it seem that all bad things done by states, corporations, or humanity, is due to Jews. Candace Owens for example recetly said that Stalin was Jewish and that the US slave trade was “not the white man but mostly Jewish”, and that Black lives now really matter to her after years of “White lives Matter” with Ye, now that she found out Jews were behind it.
