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].
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.
I think you have it backwards. Israel tolerated something like ~30k rocket attacks from Gaza (between 2005-2023) before finally launching a major military campaign that sought to remove Hamas from power.
It would normally be absurd to expect a state with military superiority to tolerate ~30k rocket attacks from its weaker neighbor. That was only tenable because Israel's air defenses mitigated the bulk of the damage.
If Israel's air defenses and bunkers suddenly disappeared, Israel would be forced to respond far more aggressively to each terrorist attack.
> 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.
I'm not sure that's true, before Iron Dome, Israel would respond to many rockets from Gaza by firing mortars back at where the rocket was launched from, often the roof of an apartment building or similar, causing civilian casualties.
After Iron Dome, a lot of rockets were simply intercepted and ignored, because there was no longer political pressure from Israelis seeing rockets land in their villages and wanting to hit back.
> 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.
Collectivism will not save us. The day after we abolish markets, prices, and capitalism, there will be as many disagreements about resource allocation as there were the day before. Some of those disagreements will spiral into conflict.
Drone tech will adapt, as it has been in the russia/ukraine conflict.
A small, fast, autonomous drone flying between trees and buildings, avoiding obstacles and not flying in a straight line could destroy such an expensive system with very little explosive.
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.
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.
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.
That laser station will not last in Ukraine an hour and will be destroyed either by missiles or drone swarm.
What Ukraine have found a net launcher is effective and cheap solution against drones and may allow more use of tanks and heavy armor vehicles again in 2026. Then shotguns with a special ammunition is effective. Then against fiber drones a fence with moving wire works surprisingly good to cut the fiber.
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.
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.
And Putin gives a nuke to Iranians then it's game over since Iranians don't care about MAD doctrine. Anyways the risk of the tech falling into Russia's hands is too high. Ukrainians have the smarts to develop it themselves now that it is proven as a viable tech.
Everyone cares about the MAD doctrine, although some people with power may pretend they do not, while others may pretend they believe that those people with power don't care.
Why would Russia give nukes to Iran? The Russians themselves would be harmed by an open nuclear exchange.
No, Putin's threats to Biden and Trump were more along the lines of, 'See the Houthis shooting shipping, imagine that capability spread to rebels and terrorists worldwide'
Similarly the insane far-right government of Israel seem hell-bent on making "Greater Israel" a reality. Iran aren't going to nuke anyone. They have no nukes nor a religious call to bring the end of times.
Christian Zionism, on the other hand, does seem to want this to happen.
This is a good article. I disagree with its implications. I would agree that the average us citizen is much too far removed from the defense industrial complex and that creates these situations where a Google engineer (not necessarily this guy) is perfectly willing to help destroy American society with his advertising tech but balks at automating image tagging for the dod's big data lake because would rather have another 9/11 than be responsible for a false positive in the ME.
How is cell phone tracking going to prevent another 9/11? And looking at the historical track record, the DoD has done a lot of killing and very little 9/11 prevention in the past 24 years.
Sure, until someone says "hey can we stick this on a truck and use it against cars?" "Hey can we stick this on the belly of a plane and use it on a building?" "Hey what happens if we do a flash of this at protestors?"
In Batman Begins, the villian just makes the drinking water toxic. With todays AI and Biotech, one can create a new bacteria or virus and cripple water supply of cities. I am sure a suitable trained AI can get more creative with such low cost attack vectors.
Nah. You can't just engineer some sort of pathogen which will survive water purification treatments, or grow and reproduce in pure water without any nutrients. Real life isn't like the movies.
This just means, the addition of the pathogen has to happen after purification treatments. Viruses can stay dormant and activate only within human body, no need for food.
It’s not going to do anything useful against cars, let alone buildings. It would blind people, and that would be bad, but it’s a very expensive way to hurt people. I think this one is for what it says it’s for.
Countries dont generally invest in shitty weapons when they already have good weapons. Bombs & missiles already exist and are much better than lasers if your goal is to destroy a stationary target.
The point is, why would they bother when there’s cheaper and easier ways to do it? A high tech laser system is great for shooting stuff down because it replaces missile systems that cost even more. If you want to cripple people, why would you use it instead of a cheap gun or baton?
“It could be used to hurt people” doesn’t mean much. You at least need “it could be used to hurt people, and it’s better at it in at least one way than what’s already available.”
Does anyone really think the country that spent millions of dollars building explosive-laden pagers that blinded and maimed children, then spent tens of millions of dollars gloating about it in public, gives a solitary thought to the cost-benefit ratio?
They have rules that say it's okay to kill 100 civilians as long as a single "operative" is also killed.
This is a country whose leadership cares only about executing terror. Just like the USA.
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.
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.
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.
If you want society to be more vulnerable to military action, then the biggest innovation is health care. Improved health care is what allowed nations to create and maintain larger military forces. Through out history, disease and malnourished caused more death by a large margin than actually violence in combat, and many war campaign stopped suddenly because one or both sides became unable to continue.
> 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.
> If something enables aggression, because it makes counter attacks unreasonable, that seems like a fairly nice thing to have more of
You’re imagining a world where this kind of tech is equally distributed. It’s not. Israel spends something like $30b/year in defense (in part due to ~$7b/year from the US). Gaza has something like $0.3b to spend. The consequence of that asymmetry is one of them has a missile shield, the other has more than 80,000 dead citizens, famine, and virtually no infrastructure left standing.
That’s gross. You’re basically saying that hundreds of millions of people need to be held as hostages to ensure good behavior, and that trying to rescue those hostages is morally wrong.
> 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.
Lol no, Iran was utterly humiliated in this conflict, and outed as a paper tiger.
The re-edited title frames this as an anti-drone system but this was foremost developed as an anti-rocket system.
Hamas and Hezbollah MO since the 1990s was based on bombing Israeli towns with statistical rockets and this system is supposed to reverse the cost equation (cheaper than those cheap rockets)
The rockets are very imprecise, but a large number of them, hitting the territory of a town, will deal damage, bodily harm, and death at random, due to statistics. It's Monte Carlo bombing of sorts :(
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
I also wonder the extent to which the effectiveness is reduced by painting the projectile white or wrapping it in aluminum foil. Maybe 100kw is so large that it simply does not matter at that power level.
It'll get a lot of time to react at that energy as it's not going to "instantly" fry anything*. That's probably less energy/m2 than consumer heat guns, especially if consider that these drones are likely going to get sprayed in reflective paint. Easy defense for the drone would be just: get into a spin to get roasted evenly -> shut off -> fall for a few hundred meters, cooling using air that rushes by to counteract the laser further -> catch itself once it lost the laser.
That would force these laser systems to point each drone until it either visibly goes up in flames or impacts the ground (which means you also need to be able to track them all the way down), otherwise you can't be sure it won't just snap back to life once you started engaging the next drone.
I don't feel like 10kw/m2 would be anywhere near useful. It's gotta be more than that.
* Stadium floodlights aren't going to instantly grill any bird that flies in front of them either, and they reach that ballpark.
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
> The power delivery was doable even 15 years ago.
Not really. It took a long time for solid state lasers to make it to 100KW. That's the power level military people have wanted for two decades.
Megawatt chemical lasers are possible, and have been built. But the ground based one was three semitrailers, and the airborne one needed a 747. Plus you ran out of chemicals fairly fast.
I took 'power delivery' to mean the systems that facilitate driving the energy into the weapon, not the beam itself -- although now under consideration of the technology I think we should probably avoid the use of the phrase 'power delivery', without a projectile being involved that's essentially the entire concept.
If these things are even 50% efficient, then power delivery is really not a problem these days. Most EVs have no problem delivering 200kW for quite a few seconds at a time, limited mostly by components getting warm. Higher-end EVs are generally rated for 300-500kW.
It would by amusing to see one of these lasers mounted on an EV, possibly with a small range extender to recharge it on the go.
They say it's first operational system in it's class, but it seems very similar to the Australian Apollo system, with Apollo being able to go up to 150kW
It's also similar to the British DragonFire and US HELIOS
I think the major difference here is that the Iron Beam is operational, as in finished trials, delivered to an armed force and actually was in active use in the previous war for more than a year
So will we get drones coated in mirrors and temperature sensors that automatically move them away from these weapons quickly? Or is the laser just too powerful?
Its really hard to make near perfect mirrors that stay perfect in rough conditions. Mirrors arent a reasonable defense to laser weapons outside of scifi.
The thing that worries me isn't the drone/anti-drone escalation. It is the fact that these weapons aren't actually limited to anti-drone use. Recently we have seen clear examples of countries, including Israel, that will use automatic id technology to mass tag a population. If you then have tools that can automatically track and mass kill, which this type of weapon represents, then we have reached a type of warfare that is new in the world and deeply scary. It isn't hard to imagine a scenario where person x is killed since they are marked as a 'bag guy' and as part of being marked every person they were next to for the last few days was also marked as likely enough to be bad guys to kill as well. All that has to be done is push a button. It is a scary, and unfortunately all to possible, future if not now.
For antipersonnel use, guns are perfectly adequate and guns on tracking turrets have been widely deployed (for example, CIWS). The underlying technology is a ballistic calculator and a fast panning turret. A weapon like this can't really "mass kill" -- it is for point targets -- but we have long had tools that can automatically track and kill. Why don't we employ them to shoot at people? We have the tagging technology, &c, as you mention.
One reason is that positive identification really does matter a lot when designing and developing weapon systems that automatically attack something.
The anti-missile use case is one of the most widespread uses for automatically targeted weapons in part because a missile is easily distinguished from other things that should not be killed: it is small, extremely hot, moves extremely fast, generally up in the air and moves towards the defense system. It is not a bird, a person, or even a friendly aircraft. The worst mistake the targeting system can make is shooting down a friendly missile. If a friendly missile is coming at you, maybe you need to shoot it down anyways...
Drones have a different signature from a missile and recognizing them in a way that doesn't confuse them with a bird, a balloon, &c, is different from recognizing missiles -- but here again, the worse thing that happens is you shoot down a friendly drone.
It seems incredibly hard to imagine what else you would do with a ground based laser other than shoot at incoming projectiles. What exactly are you expecting the Israelis to do? Change the laws of physics?
Mirrors are not effective enough. Shielding drones from energy weapons seems like a similar problem to entering Earth’s atmosphere, you want to shield it in a way that will blast away safely and ideally diffuse the laser, so the energy is spread over a larger space.
I suspect larger lasers will likely aways win, since there is only so much shielding can do. At which point we could end up with transformers like drones that are built to be broken apart mid flight and yet still deliver damage.
I feel like defending drones could become possible with energy weapons but only under ideal weather conditions.
Likely cheaper to just coat the real drones in an aerogel or similar light weight, high thermal resistance material. It's an arms race still, but one with a reasonable amount of asymmetry in favour of an attacker.
No, but an AI drone like the one Turkey has can probably detect the source of the beam by hiding behind some sacrificial/decoy drones and watching them blow up then shooting a missile at the laser source. It's not like the laser is coming out of thin air.
actually it's for shooting anything that is close enough and can be intercepted.
during the war with hezbollah (drones were issue due to topography) lower power version of iron beam was deployed on trial bases and scored around 40 intercepts
Gaza (Hamas), the West Bank (Fatah), and Lebanon (Hezbollah) are the reason this technology is needed in the first place: violent religious fundamentalists firing cheap rockets at Jewish cities because of religious hatred. Over 16,000 rocket attacks on Israel last year alone.
Thanks to the Iron Dome technology, nearly 90% of such attacks were intercepted, saving thousands of lives.
This new Iron Beam technology is more precise and cheaper, and will likely save even more lives.
That's not how it looks like though with the way Israel acts like the judge, jury and executioner of the region. You get the feeling that only Israeli lives count in the Middle East.
you could alternatively pount towards israeli expansionism, which is a bit more likely than religious extremism. demolish peoples homes and kidnap their families, and theyre gonna respond in whatever way they can.
i expect the iron beam is going to make a lot more deaths, just of people israelis dont consider human. wooo
Except agreeing to a peace deal and state recognition... with Ehud Barak or Ehud Olmert. And Except letting their citizens vote for their own gov in Gaza for over 17 years...
I guess responding to Israeli expansionism has some great strategy I still don't grasp.
This is hasbara. You need to learn more about Israeli history. Hamas was elected with the support of Netanyahu et al. And 50% of the people in Gaza weren’t even alive when Hamas was elected. (However many of them remain. The death toll after Oct 7 will probably be around 500,000 dead)
Israel has never been interested in a peace deal.
It is a settler colonialist project in the finest traditions of such with the aim of conquering the entire region. And the US and friends support it for racist and capitalist reasons.
>This new Iron Beam technology is more precise and cheaper, and will likely save even more (israeli) lives.
There fixed it for you. last I checked, Israelis are using drones to summarily execute Palestinian kids with impunity. the idea of these people having even more weapons at their disposal paid for by MY tax dollars leaves me a bit disgusted.
> violent religious fundamentalists firing ... cities because of religious hatred
Some tend to be more introspective:
Shahak's Jewish Fundamentalism in Israel picked up on the theme in explaining its pervasive, destructive influence in Israeli politics, the military and society. He noted that substituting German or Aryan for Jewish and non-Jews for Jews makes it easy to see how a superiority doctrine made an earlier genocide possible and is letting another happen now. Shahak called all forms of bigotry morally reprehensible and said: "Any form of racism, discrimination and xenophobia becomes more potent and politically influential if it is taken for granted by the society which indulges in it." For Israeli Jews, he believed, "The support of democracy and human rights is... meaningless or even harmful and deceitful when it does not begin with self-critique and with support of human rights when they are violated by one's own group. Any support of human rights for non-Jews whose rights are being violated by the 'Jewish state' is as deceitful as the support of human rights by a Stalinist..."
Kook was Israel's first chief rabbi. In his honour, and to continue his teachings, the extremist Merkaz Harav (the Rabbi's Centre) was founded in 1924 as a yeshiva or fundamentalist religious college. It teaches that, "non-Jews living under Jewish law in Eretz Yisrael (the Land of Israel) must either be enslaved as water carriers and wood hewers, or banished, or exterminated."
Chief military rabbi, Brigadier General Avichai Rontzki, called Operation Cast Lead a "religious war" in which it was "immoral" to show mercy to an enemy of "murderers". Many others feel the same way, prominently among them graduates of Hesder Yeshivat schools that combine extremist religious indoctrination with military service to defend the Jewish state.
Others in Israel teach the extremist notion that the 10 Commandments don't apply to non-Jews. So killing them in defending the homeland is acceptable, and according to Rabbi Dov Lior, chairman of the Jewish Rabbinic Council: "There is no such thing as enemy civilians in war time. The law of our Torah is to have mercy on our soldiers and to save them... A thousand non-Jewish lives are not worth a Jew's fingernail."
In June 2009, US Hasidic Rabbi Manis Friedman voiced a similar sentiment in calling on Israel to kill Palestinian "men, women and children". "I don't believe in Western morality, ie don't kill civilians or children, don't destroy holy sites, don't fight during the holiday seasons, don't bomb cemeteries, and don't shoot until they shoot first because it is immoral. The only way to fight a moral war is the Jewish way: destroy their holy sites. Kill men, women and children (and cattle)."
...
Though a minority, Israel's religious community wields considerable influence politically, in the military and society overall.
...
How the future balance of power shifts from one side to the other will greatly influence the makeup of future Israeli governments and determine whether peaceful co- existence can replace over six decades of conflict and repression. So far it hasn't, and nothing suggests it will any time soon; not while extremist Zionists run the government, serve prominently in the Israeli army, and -- according to critics -- are gaining more power incrementally.
I mean... let's not throw stones from an equally spectacular glass house.
There isnt much information here. What is the total power per m^2 and what is the frequency (range). As we know the sun alone is 1kW/m^2 over quite a range.
Shaheds are heavy and big and I doubt that the new laser system can damage them. An interceptor drone is much cheaper and effective against them. This is more like defense against smaller FPV drones targeting bigger anti-missile systems.
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.
We are also lucky a miscalculation didn’t occur during the Cold War resulting in millions of nuked folks. But, not sure what the alternative is. Best idea I’ve heard is for everyone to stop reproducing.
More to the point, "technology is neither good, nor bad, nor neutral, it just exists". Ultimately all tools can be used for good or bad purposes and what matters is the people who wield them.
This is separate from the argument over whether MAD is philosophically good. MAD is not an argument about technology. "Peace through strength" does indeed require the occasional display of strength, to maintain deterrence. Good and bad (morals) are not the right frame to understand deterrence, rather emotions: fear, confidence, and security.
Solzhenitsyn can be read as either a humanist or an ethicist: either the bridgehead of good is sufficient to redeem everyone from war and morality demands pacifism, or all military doctrines must be submitted to independent review to check that we do not give the "unuprooted small corner of evil" oxygen. Crucially, these are both judgements about ourselves and not about the foes who seek to destroy us, who indeed consider themselves to have "the best of all hearts". In this sense, Solzhenitsyn contributes to the cycle of violence: if both sides are ethicists, and their ethical councils have different conclusions, the result is not just fundamentalism but a fundamentalism justified by ethical review.
Fear, anger, disgust are the ultimate drivers of conflict. Can we conquer them? Of course not, they are the base emotions, part of being human. But can there be a better way of handling them in geopolitics? Yes - if leaders are focused on helping not just themselves feel safe, but their enemies as well. This is the higher level beyond MAD - not mutual fear, but mutual security. This is why USAID was great foreign policy and cheap for its benefits. This is why weapons are sold to allies despite the fact that their interests may not be fully aligned with ours. Weapons are fundamental to security, which at the end of the day is a feeling and not a guarantee against attack or repercussions from an attack, and these feelings of security are what reduces the incidence and frequence of war.
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.
Someone will find a reflexive material to put on the drone. Then you have a multi kw laser that hits randomly anywhere when intercepting drones.
Also I wonder why it is not common to run interception drones that automatically fly towards incoming drones and captures them mid air. Like a wasp is capturing other insects.
So pretty much like the iron dome but not with single use rockets but reusable drones instead.
Laser weapons appear to be advancing rapidly. Once we get to the single digit MW power range, MAD will deteriorate as the ICBM becomes a non-viable nuclear delivery mechanism.
What effect would that have? Will nukes start getting used in wars? Will we see deployment of multi ton NEFP[1] warheads that can strike targets with nuclear-propelled kinetics?
there was interview with guy from rafael who was head of iron beam project. it looks like they have some plans for dealing with icbm. airborne if I understood correctly
I guess airborne would be easier to intercept in their earlier phase before they go super fast, but then you have to have air assets in the right place at the right time.
At their terminal phase icbms go at mach 25, which is pretty hard to shine a laser on for an extended period of time.
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].

Except when the bombardment comes from space.
Golden Dome is planning large constellations of lasers like this in constant orbit, as well as hypersonic warheads able to target any spot on Earth within 90 seconds https://en.wikipedia.org/wiki/Golden_Dome_(missile_defense_s...
It's explicitly an offensive technology (and of course Musk has been involved)
> It means that innocent citizens will be protected from constant bombardment or thread of bombardment by cheap mass produced rockets or drones
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.
They have economic related riots starting as we speak so the progressive end result (a few riots down the line) might either be this or regime change
Riots are going to end predictably badly when those participating do not have guns. Just like a couple years ago other there. Probably a lesson here.
It's usually progressive until the people with guns are too afraid to shoot, as in the fall of USSR
Although I will believe there are a few more iterations before this regime falls
They haven't done so in decades. You think they'll start now?
> You think they'll start now?
No. But I can hope.
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.

I think you have it backwards. Israel tolerated something like ~30k rocket attacks from Gaza (between 2005-2023) before finally launching a major military campaign that sought to remove Hamas from power.
It would normally be absurd to expect a state with military superiority to tolerate ~30k rocket attacks from its weaker neighbor. That was only tenable because Israel's air defenses mitigated the bulk of the damage.
If Israel's air defenses and bunkers suddenly disappeared, Israel would be forced to respond far more aggressively to each terrorist attack.
> 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.
I'm not sure that's true, before Iron Dome, Israel would respond to many rockets from Gaza by firing mortars back at where the rocket was launched from, often the roof of an apartment building or similar, causing civilian casualties.
After Iron Dome, a lot of rockets were simply intercepted and ignored, because there was no longer political pressure from Israelis seeing rockets land in their villages and wanting to hit back.
> 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.
Collectivism will not save us. The day after we abolish markets, prices, and capitalism, there will be as many disagreements about resource allocation as there were the day before. Some of those disagreements will spiral into conflict.
'people shouldn't have locks on their doors, they discourage them from improving society'
'moving from wooden shingles allows society to be negligent when it comes to fire/forestry management and makes the world worse'
Drone tech will adapt, as it has been in the russia/ukraine conflict.
A small, fast, autonomous drone flying between trees and buildings, avoiding obstacles and not flying in a straight line could destroy such an expensive system with very little explosive.
Or a cloud of such drones.
Or launch your attack on a foggy/rainy day.
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.
This will be vital tech after China swarms Taiwan with a massive drone invasion.
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.
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.
Maybe Hi Tech weapon is impressive but that could lure us into false sense of security. Israel learnt the lesson the hard way in the October 7 attack.
That laser station will not last in Ukraine an hour and will be destroyed either by missiles or drone swarm.
What Ukraine have found a net launcher is effective and cheap solution against drones and may allow more use of tanks and heavy armor vehicles again in 2026. Then shotguns with a special ammunition is effective. Then against fiber drones a fence with moving wire works surprisingly good to cut the fiber.
you should tell it to ukrainians. because they are busy developing their own laser system https://thedefensepost.com/2025/04/15/ukraine-unveils-laser-...
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.
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.
Are you factoring in the cost in human lives?
Human lives are pretty cheap all things considered.
Lets send some over to Ukraine.
And Putin gives a nuke to Iranians then it's game over since Iranians don't care about MAD doctrine. Anyways the risk of the tech falling into Russia's hands is too high. Ukrainians have the smarts to develop it themselves now that it is proven as a viable tech.
Everyone cares about the MAD doctrine, although some people with power may pretend they do not, while others may pretend they believe that those people with power don't care.
Why would Russia give nukes to Iran? The Russians themselves would be harmed by an open nuclear exchange.
No, Putin's threats to Biden and Trump were more along the lines of, 'See the Houthis shooting shipping, imagine that capability spread to rebels and terrorists worldwide'
iran has a religious rule against making nukes, to the same extent that it has religious decrees calling for an end to israel.
iranians arent gonna nuke anyone without first toppling their religious government
Similarly the insane far-right government of Israel seem hell-bent on making "Greater Israel" a reality. Iran aren't going to nuke anyone. They have no nukes nor a religious call to bring the end of times.
Christian Zionism, on the other hand, does seem to want this to happen.
Iran has an active nuclear weapons program which the Israelis keep sabotaging.
Don't Get Distracted
https://calebhearth.com/dont-get-distracted
This is a good article. I disagree with its implications. I would agree that the average us citizen is much too far removed from the defense industrial complex and that creates these situations where a Google engineer (not necessarily this guy) is perfectly willing to help destroy American society with his advertising tech but balks at automating image tagging for the dod's big data lake because would rather have another 9/11 than be responsible for a false positive in the ME.
How is cell phone tracking going to prevent another 9/11? And looking at the historical track record, the DoD has done a lot of killing and very little 9/11 prevention in the past 24 years.
Do they have a public log of preventions we can look at? Seems fascinating to look at the numbers
The heuristic is that it would be in their interest to trumpet their successes.
Not if revealing success also reveals methodology and “trade” secrets.
Its perfectly reasonable to suppose undisclosed successes are imaginary as that is the overwhelming likelihood
What could these secrets be other than a completely illegal comprehensive web of domestic spy apparatus.
hey man what country were the 9/11 hijackers from? What counties did we invade and which did we give f-35’s to?
This is designed to save people.
Sure, until someone says "hey can we stick this on a truck and use it against cars?" "Hey can we stick this on the belly of a plane and use it on a building?" "Hey what happens if we do a flash of this at protestors?"
Those kinds of tests have been done with lasers already.
This is a defensive application of lasers, like CIWS is a defensive application of guns.
We already have very cheap and effective ways to kill people.
Not so much when it comes to drone swarms.
My understand is it would be useless against a building, but you make a good point
Which will happen because it always happens
Then when that happens that might be morally objectionable. But probably like any other weapon that already exists, a rocket, missile or gun.
While not everyday a new defense systems is invented that is targeted at statistical weapon that terrorizes civilians.
In Batman Begins, the villian just makes the drinking water toxic. With todays AI and Biotech, one can create a new bacteria or virus and cripple water supply of cities. I am sure a suitable trained AI can get more creative with such low cost attack vectors.
Nah. You can't just engineer some sort of pathogen which will survive water purification treatments, or grow and reproduce in pure water without any nutrients. Real life isn't like the movies.
This just means, the addition of the pathogen has to happen after purification treatments. Viruses can stay dormant and activate only within human body, no need for food.
AI Labs Do "Gain-Of-Function" Research
https://www.youtube.com/shorts/yVSihOtF4ZA
It’s not going to do anything useful against cars, let alone buildings. It would blind people, and that would be bad, but it’s a very expensive way to hurt people. I think this one is for what it says it’s for.
"It's a very expensive way to hurt people" has historically never been a real deterrent to motivated nation states to bring costs down
Countries dont generally invest in shitty weapons when they already have good weapons. Bombs & missiles already exist and are much better than lasers if your goal is to destroy a stationary target.
The point is, why would they bother when there’s cheaper and easier ways to do it? A high tech laser system is great for shooting stuff down because it replaces missile systems that cost even more. If you want to cripple people, why would you use it instead of a cheap gun or baton?
“It could be used to hurt people” doesn’t mean much. You at least need “it could be used to hurt people, and it’s better at it in at least one way than what’s already available.”
Does anyone really think the country that spent millions of dollars building explosive-laden pagers that blinded and maimed children, then spent tens of millions of dollars gloating about it in public, gives a solitary thought to the cost-benefit ratio?
They have rules that say it's okay to kill 100 civilians as long as a single "operative" is also killed.
This is a country whose leadership cares only about executing terror. Just like the USA.
Yet the pager attack did help wipe out most of the Hezbollah leadership and shortened the war overall.
Without it, Lebanon might be looking a lot more like Gaza right now.
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.
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.
> 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.
If you want society to be more vulnerable to military action, then the biggest innovation is health care. Improved health care is what allowed nations to create and maintain larger military forces. Through out history, disease and malnourished caused more death by a large margin than actually violence in combat, and many war campaign stopped suddenly because one or both sides became unable to continue.
> 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.
> If something enables aggression, because it makes counter attacks unreasonable, that seems like a fairly nice thing to have more of
You’re imagining a world where this kind of tech is equally distributed. It’s not. Israel spends something like $30b/year in defense (in part due to ~$7b/year from the US). Gaza has something like $0.3b to spend. The consequence of that asymmetry is one of them has a missile shield, the other has more than 80,000 dead citizens, famine, and virtually no infrastructure left standing.
That’s gross. You’re basically saying that hundreds of millions of people need to be held as hostages to ensure good behavior, and that trying to rescue those hostages is morally wrong.
> 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.
Lol no, Iran was utterly humiliated in this conflict, and outed as a paper tiger.
it's almost as if it is unrelated to the article discussed
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.
The re-edited title frames this as an anti-drone system but this was foremost developed as an anti-rocket system.
Hamas and Hezbollah MO since the 1990s was based on bombing Israeli towns with statistical rockets and this system is supposed to reverse the cost equation (cheaper than those cheap rockets)
Today this is also used for drones though
Statistical rockets?
The rockets are very imprecise, but a large number of them, hitting the territory of a town, will deal damage, bodily harm, and death at random, due to statistics. It's Monte Carlo bombing of sorts :(
How far away is the laser beam lethal? Could it accidentally bring down a plane flying behind the laser? Or a satellite?
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?
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
I also wonder the extent to which the effectiveness is reduced by painting the projectile white or wrapping it in aluminum foil. Maybe 100kw is so large that it simply does not matter at that power level.
I imagine that it depends greatly on the laser’s spectrum. Aluminium is a good reflector of infrared but not ultraviolet, for example.
Maybe it involves multiple converging beams to reduce transmission losses?
yes it does
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
It'll get a lot of time to react at that energy as it's not going to "instantly" fry anything*. That's probably less energy/m2 than consumer heat guns, especially if consider that these drones are likely going to get sprayed in reflective paint. Easy defense for the drone would be just: get into a spin to get roasted evenly -> shut off -> fall for a few hundred meters, cooling using air that rushes by to counteract the laser further -> catch itself once it lost the laser.
That would force these laser systems to point each drone until it either visibly goes up in flames or impacts the ground (which means you also need to be able to track them all the way down), otherwise you can't be sure it won't just snap back to life once you started engaging the next drone.
I don't feel like 10kw/m2 would be anywhere near useful. It's gotta be more than that.
* Stadium floodlights aren't going to instantly grill any bird that flies in front of them either, and they reach that ballpark.
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
> The power delivery was doable even 15 years ago.
Not really. It took a long time for solid state lasers to make it to 100KW. That's the power level military people have wanted for two decades.
Megawatt chemical lasers are possible, and have been built. But the ground based one was three semitrailers, and the airborne one needed a 747. Plus you ran out of chemicals fairly fast.
I took 'power delivery' to mean the systems that facilitate driving the energy into the weapon, not the beam itself -- although now under consideration of the technology I think we should probably avoid the use of the phrase 'power delivery', without a projectile being involved that's essentially the entire concept.
Wouldn’t they be able to just use radars?
I guess they are using it in pulsed mode, continuous mode would be a little bit much power
Depends on how tightly they can focus the beam.
http://panoptesv.com/SciFi/LaserDeathRay/DamageFromLaser.php
Hm, you think longer than the laser is firing? Could there be windup?
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.
If these things are even 50% efficient, then power delivery is really not a problem these days. Most EVs have no problem delivering 200kW for quite a few seconds at a time, limited mostly by components getting warm. Higher-end EVs are generally rated for 300-500kW.
It would by amusing to see one of these lasers mounted on an EV, possibly with a small range extender to recharge it on the go.
Ah, good point, that seems likely.
few seconds. it (lower power version) was deployed during war with hezbollah and intercepted 40 drones (big one, not fpv).
there is footage of intercepts out there. was released about half an year ago
They say it's first operational system in it's class, but it seems very similar to the Australian Apollo system, with Apollo being able to go up to 150kW
https://eos-aus.com/defence/high-energy-laser-weapon/apollo/
It's also similar to the British DragonFire and US HELIOS
I think the major difference here is that the Iron Beam is operational, as in finished trials, delivered to an armed force and actually was in active use in the previous war for more than a year
apollo range according to site is 3km. iron beam 10km
from what I understand, problem with drones is first of all detection
Well there's drones, then there's prop driven cheap cruise missiles.
I think we're talking the second.
let me up the ante, drones intermixed with kamikaze pigeons.
So will we get drones coated in mirrors and temperature sensors that automatically move them away from these weapons quickly? Or is the laser just too powerful?
Its really hard to make near perfect mirrors that stay perfect in rough conditions. Mirrors arent a reasonable defense to laser weapons outside of scifi.
what about mirrors with tiny little windshield wipers?
The thing that worries me isn't the drone/anti-drone escalation. It is the fact that these weapons aren't actually limited to anti-drone use. Recently we have seen clear examples of countries, including Israel, that will use automatic id technology to mass tag a population. If you then have tools that can automatically track and mass kill, which this type of weapon represents, then we have reached a type of warfare that is new in the world and deeply scary. It isn't hard to imagine a scenario where person x is killed since they are marked as a 'bag guy' and as part of being marked every person they were next to for the last few days was also marked as likely enough to be bad guys to kill as well. All that has to be done is push a button. It is a scary, and unfortunately all to possible, future if not now.
It's been possible for a long time.
For antipersonnel use, guns are perfectly adequate and guns on tracking turrets have been widely deployed (for example, CIWS). The underlying technology is a ballistic calculator and a fast panning turret. A weapon like this can't really "mass kill" -- it is for point targets -- but we have long had tools that can automatically track and kill. Why don't we employ them to shoot at people? We have the tagging technology, &c, as you mention.
One reason is that positive identification really does matter a lot when designing and developing weapon systems that automatically attack something.
The anti-missile use case is one of the most widespread uses for automatically targeted weapons in part because a missile is easily distinguished from other things that should not be killed: it is small, extremely hot, moves extremely fast, generally up in the air and moves towards the defense system. It is not a bird, a person, or even a friendly aircraft. The worst mistake the targeting system can make is shooting down a friendly missile. If a friendly missile is coming at you, maybe you need to shoot it down anyways...
Drones have a different signature from a missile and recognizing them in a way that doesn't confuse them with a bird, a balloon, &c, is different from recognizing missiles -- but here again, the worse thing that happens is you shoot down a friendly drone.
It seems incredibly hard to imagine what else you would do with a ground based laser other than shoot at incoming projectiles. What exactly are you expecting the Israelis to do? Change the laws of physics?
I think we’re already there. Sounds like Obama administration hit jobs.

Probably a dumb question, but could a ploy drone fitted with a directional mirror redirect the beam back to the source to damage or destroy it?
Mirrors are not effective enough. Shielding drones from energy weapons seems like a similar problem to entering Earth’s atmosphere, you want to shield it in a way that will blast away safely and ideally diffuse the laser, so the energy is spread over a larger space. I suspect larger lasers will likely aways win, since there is only so much shielding can do. At which point we could end up with transformers like drones that are built to be broken apart mid flight and yet still deliver damage. I feel like defending drones could become possible with energy weapons but only under ideal weather conditions.
Likely cheaper to just coat the real drones in an aerogel or similar light weight, high thermal resistance material. It's an arms race still, but one with a reasonable amount of asymmetry in favour of an attacker.
I'm not certain, but I think the returned beam would likely be significantly out-of-focus.
No, but an AI drone like the one Turkey has can probably detect the source of the beam by hiding behind some sacrificial/decoy drones and watching them blow up then shooting a missile at the laser source. It's not like the laser is coming out of thin air.
Shooting down missiles is what this is for.
actually it's for shooting anything that is close enough and can be intercepted. during the war with hezbollah (drones were issue due to topography) lower power version of iron beam was deployed on trial bases and scored around 40 intercepts
Someone should give people in Gaza or the West Bank or Lebanon the same tech.
Gaza (Hamas), the West Bank (Fatah), and Lebanon (Hezbollah) are the reason this technology is needed in the first place: violent religious fundamentalists firing cheap rockets at Jewish cities because of religious hatred. Over 16,000 rocket attacks on Israel last year alone.
Thanks to the Iron Dome technology, nearly 90% of such attacks were intercepted, saving thousands of lives.
This new Iron Beam technology is more precise and cheaper, and will likely save even more lives.
That's not how it looks like though with the way Israel acts like the judge, jury and executioner of the region. You get the feeling that only Israeli lives count in the Middle East.
you could alternatively pount towards israeli expansionism, which is a bit more likely than religious extremism. demolish peoples homes and kidnap their families, and theyre gonna respond in whatever way they can.
i expect the iron beam is going to make a lot more deaths, just of people israelis dont consider human. wooo
> whatever way they can.
Except agreeing to a peace deal and state recognition... with Ehud Barak or Ehud Olmert. And Except letting their citizens vote for their own gov in Gaza for over 17 years...
I guess responding to Israeli expansionism has some great strategy I still don't grasp.
This is hasbara. You need to learn more about Israeli history. Hamas was elected with the support of Netanyahu et al. And 50% of the people in Gaza weren’t even alive when Hamas was elected. (However many of them remain. The death toll after Oct 7 will probably be around 500,000 dead)
Israel has never been interested in a peace deal.
It is a settler colonialist project in the finest traditions of such with the aim of conquering the entire region. And the US and friends support it for racist and capitalist reasons.
>This new Iron Beam technology is more precise and cheaper, and will likely save even more (israeli) lives.
There fixed it for you. last I checked, Israelis are using drones to summarily execute Palestinian kids with impunity. the idea of these people having even more weapons at their disposal paid for by MY tax dollars leaves me a bit disgusted.
> violent religious fundamentalists firing ... cities because of religious hatred
Some tend to be more introspective:
I mean... let's not throw stones from an equally spectacular glass house.There isnt much information here. What is the total power per m^2 and what is the frequency (range). As we know the sun alone is 1kW/m^2 over quite a range.
Just in time for Iran 2.0
In the war in June, Iran fired 500kg warhead ballistic missiles. These were the only lethal munition they used, killing a couple dozen civilians.
The Iron Beam is not relevant against ballistic missiles.
> Iran fired 500kg warhead ballistic missiles
Iran also fired “over 1,000 suicide drones” [1].
[1] https://en.wikipedia.org/wiki/Iran%E2%80%93Israel_war
Shaheds are heavy and big and I doubt that the new laser system can damage them. An interceptor drone is much cheaper and effective against them. This is more like defense against smaller FPV drones targeting bigger anti-missile systems.
Flying disco balls when?
They certainly have those for radars! Although the reason for using them is different.
https://en.wikipedia.org/wiki/Corner_reflector
I wish they would make a demonstration
I guess they could use railguns too.
It is so sad the Humanity needs to develop weapons...
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)
We are also lucky a miscalculation didn’t occur during the Cold War resulting in millions of nuked folks. But, not sure what the alternative is. Best idea I’ve heard is for everyone to stop reproducing.
More to the point, "technology is neither good, nor bad, nor neutral, it just exists". Ultimately all tools can be used for good or bad purposes and what matters is the people who wield them.
This is separate from the argument over whether MAD is philosophically good. MAD is not an argument about technology. "Peace through strength" does indeed require the occasional display of strength, to maintain deterrence. Good and bad (morals) are not the right frame to understand deterrence, rather emotions: fear, confidence, and security.
Solzhenitsyn can be read as either a humanist or an ethicist: either the bridgehead of good is sufficient to redeem everyone from war and morality demands pacifism, or all military doctrines must be submitted to independent review to check that we do not give the "unuprooted small corner of evil" oxygen. Crucially, these are both judgements about ourselves and not about the foes who seek to destroy us, who indeed consider themselves to have "the best of all hearts". In this sense, Solzhenitsyn contributes to the cycle of violence: if both sides are ethicists, and their ethical councils have different conclusions, the result is not just fundamentalism but a fundamentalism justified by ethical review.
Fear, anger, disgust are the ultimate drivers of conflict. Can we conquer them? Of course not, they are the base emotions, part of being human. But can there be a better way of handling them in geopolitics? Yes - if leaders are focused on helping not just themselves feel safe, but their enemies as well. This is the higher level beyond MAD - not mutual fear, but mutual security. This is why USAID was great foreign policy and cheap for its benefits. This is why weapons are sold to allies despite the fact that their interests may not be fully aligned with ours. Weapons are fundamental to security, which at the end of the day is a feeling and not a guarantee against attack or repercussions from an attack, and these feelings of security are what reduces the incidence and frequence of war.
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.
Weapons are why we exist in the first place.
100 kW. That's a lot. I wonder how many kW will be needed to save them from God's wrath
Someone will find a reflexive material to put on the drone. Then you have a multi kw laser that hits randomly anywhere when intercepting drones.
Also I wonder why it is not common to run interception drones that automatically fly towards incoming drones and captures them mid air. Like a wasp is capturing other insects.
So pretty much like the iron dome but not with single use rockets but reusable drones instead.
Laser weapons appear to be advancing rapidly. Once we get to the single digit MW power range, MAD will deteriorate as the ICBM becomes a non-viable nuclear delivery mechanism.
What effect would that have? Will nukes start getting used in wars? Will we see deployment of multi ton NEFP[1] warheads that can strike targets with nuclear-propelled kinetics?

> Once we get to the single digit MW power range, MAD will deteriorate as the ICBM becomes a non-viable nuclear delivery mechanism.
Requires a mountain of evidence and argument.
The best public arguments I have read:

We are nowhere near that point yet. Small rockets are totally different weapons then ICBM.
there was interview with guy from rafael who was head of iron beam project. it looks like they have some plans for dealing with icbm. airborne if I understood correctly
I guess airborne would be easier to intercept in their earlier phase before they go super fast, but then you have to have air assets in the right place at the right time.
At their terminal phase icbms go at mach 25, which is pretty hard to shine a laser on for an extended period of time.
to deploy it in space can also be an option
