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?"
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.”
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.

Lol no, Iran was utterly humiliated in this conflict, and outed as a paper tiger.
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.
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.
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
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.
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
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.
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.
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.
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'
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.
Next up we'll be hearing about the virtues of V2 in the Nazi arsenal. Fun tech. Still does not erase the bad feelings from seeing kids shot at intentionally from drones, or submarine launched drones throwing incendiary munitions at a flotilla featuring my fellow countrymen from the same fucking country designing this laser. Fuck Israel.
Anytime somebody makes a claim about a drone operating a firearm, you should be extremely skeptical. There's a reason everyone uses explosive drones, not "drone with a machine gun". Small flying machines trying to fire off rounds doesn't work out.
> submarine launched drones throwing incendiary munitions at a flotilla
Per the Greek coastguard, someone left a lit joint by a fuel canister. Maybe the Greeks are in on the deep conspiracy.. or potheads are just forgetful.
whenever you see someone making the claim that a gun won't work on an aircraft, I urge you to look at our entire aviation history of vehicles with guns strapped on. Planes, helicopters, jet-packs, 'manned platforms', whatever your fancy.
we're not talking about glocks ductaped to DJIs here, and all of these mysterious engineer efforts that 'just doesn't work out' are hurdles that man has faced and conquered before.
What I would suggest is that if anyone trying to give you a technical reason that ends in "It just doesn't work" they are probably unprepared to accurately brief you on the topic.
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.
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.
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.
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.
> 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.
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.
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
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 recogonization... 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 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.
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.
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
The presupposition here being that Israel has a right to defense and that the poor people being occupied, living under apartheid, being slaughtered and displaced should possess no such right to resist, has been a hallmark of zionist propaganda for ages now.
Its pretty well established in international law and the UN charter that all countries have a right to self-defense. Given this is a purely defensive weapon, i can't imagine what reasonable objection anyone could have to it.
I think Israel has a right to defense qua state and Palestinians have a right to resist qua subjects of unjust rule. These aren’t really contradictory positions, and both are pretty standard from a “this is what the UN says” ground truth[1][2].
(This is distinct from a state’s “right to exist,” which is nonsense. But once a state does exist, it has the right to defend itself by definition.)
If they both have a right to kill each other, does the other really have a right to defense? Making it complicated introduces legalistic flaws and distracts everyone from actually fixing it by doing something simple, like tying sanctions to murders of civillians.
They don’t both have a right to kill each other! Both “defense” and “resistance” (w/r/t the goal of self determination) have precise bounds; not all forms of warfare or violence are considered justifiable under either. Much of what Israel has done in the current conflict goes well beyond a charitable read of its right to defense, but this doesn’t imply that all defense adaptations are illegitimate.
I think everyone (myself included) has a right to actual self-defense, just not the false version we've been seeing.
Here's my peace plan:
Blow up or starve kids on the other side +1 sanctions.
Intercept a drone or rocket +0 sanctions.
Say you're sorry and reduce arms by 10% -1 sanctions.
If the US alone did this they'd stop with all the murders in days to weeks.
Of course the state of affairs where random online commenters can think of better answers than the individuals in charge is only due to a lack of a desire for peace at high levels! There is nothing complicated about it at all.
This is an astonishing revisionist take on the reality on the ground.
Israel unilaterally disengaged from GAZA in 2005 and pulling out generations of Jewish settlement in the process. By 2006 GAZA has zero Jews, and 2007 Gazans elected HAMAS who fired rockets at Israel because they want to free Palestine from the river to the sea, AKA eliminate Israel. October 7 attack is a culmination of that, and between then and now, HAMAS didn't forget to build their military base in the mix of civilians and using civilian targets as shield. So that they can blame Israel for every single Palestinians death, including the death cause by their own firing.
The situation in west Bank is qualitatively the same.
No, protecting your people from terrorist is not apartheid, and Israel has no interest to build iron beam and/or build wall--which the west misinterprete as apartheid-- if the neighbors had no intention to eliminate them.
The issue with that type of reasoning is that if you swapped the parties the sentences would be the same. "Palestine removed generations of settlements from Israel, but was forced to attack because Israel wanted to wipe them out." You need to think in terms of principles that can apply equally to everybody.
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.
It’s disappointing to keep being shown that if HN was around in the 40s, it would overall be condemning the Warsaw ghetto uprising and arguing all those living there should be further punished.
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.
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.

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.
it's almost as if it is unrelated to the article discussed
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?"
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.
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?

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.
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.
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
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.

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
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.
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

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.
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.
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
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'
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.
Next up we'll be hearing about the virtues of V2 in the Nazi arsenal. Fun tech. Still does not erase the bad feelings from seeing kids shot at intentionally from drones, or submarine launched drones throwing incendiary munitions at a flotilla featuring my fellow countrymen from the same fucking country designing this laser. Fuck Israel.
> seeing kids shot at intentionally from drones
Anytime somebody makes a claim about a drone operating a firearm, you should be extremely skeptical. There's a reason everyone uses explosive drones, not "drone with a machine gun". Small flying machines trying to fire off rounds doesn't work out.
> submarine launched drones throwing incendiary munitions at a flotilla
Per the Greek coastguard, someone left a lit joint by a fuel canister. Maybe the Greeks are in on the deep conspiracy.. or potheads are just forgetful.
whenever you see someone making the claim that a gun won't work on an aircraft, I urge you to look at our entire aviation history of vehicles with guns strapped on. Planes, helicopters, jet-packs, 'manned platforms', whatever your fancy.
we're not talking about glocks ductaped to DJIs here, and all of these mysterious engineer efforts that 'just doesn't work out' are hurdles that man has faced and conquered before.
What I would suggest is that if anyone trying to give you a technical reason that ends in "It just doesn't work" they are probably unprepared to accurately brief you on the topic.
Ah yes, fundamentalist groups. You know, ethno-theocracies. There's one missing from your list here.
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.
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-...
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.
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.
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.

> 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'
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.
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?

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
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 recogonization... 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 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.
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.
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
The presupposition here being that Israel has a right to defense and that the poor people being occupied, living under apartheid, being slaughtered and displaced should possess no such right to resist, has been a hallmark of zionist propaganda for ages now.
It's not aging particularly well.
Its pretty well established in international law and the UN charter that all countries have a right to self-defense. Given this is a purely defensive weapon, i can't imagine what reasonable objection anyone could have to it.
I think Israel has a right to defense qua state and Palestinians have a right to resist qua subjects of unjust rule. These aren’t really contradictory positions, and both are pretty standard from a “this is what the UN says” ground truth[1][2].
(This is distinct from a state’s “right to exist,” which is nonsense. But once a state does exist, it has the right to defend itself by definition.)

If they both have a right to kill each other, does the other really have a right to defense? Making it complicated introduces legalistic flaws and distracts everyone from actually fixing it by doing something simple, like tying sanctions to murders of civillians.
They don’t both have a right to kill each other! Both “defense” and “resistance” (w/r/t the goal of self determination) have precise bounds; not all forms of warfare or violence are considered justifiable under either. Much of what Israel has done in the current conflict goes well beyond a charitable read of its right to defense, but this doesn’t imply that all defense adaptations are illegitimate.
I think everyone (myself included) has a right to actual self-defense, just not the false version we've been seeing.
Here's my peace plan: Blow up or starve kids on the other side +1 sanctions. Intercept a drone or rocket +0 sanctions. Say you're sorry and reduce arms by 10% -1 sanctions.
If the US alone did this they'd stop with all the murders in days to weeks.
Of course the state of affairs where random online commenters can think of better answers than the individuals in charge is only due to a lack of a desire for peace at high levels! There is nothing complicated about it at all.
This is an astonishing revisionist take on the reality on the ground.
Israel unilaterally disengaged from GAZA in 2005 and pulling out generations of Jewish settlement in the process. By 2006 GAZA has zero Jews, and 2007 Gazans elected HAMAS who fired rockets at Israel because they want to free Palestine from the river to the sea, AKA eliminate Israel. October 7 attack is a culmination of that, and between then and now, HAMAS didn't forget to build their military base in the mix of civilians and using civilian targets as shield. So that they can blame Israel for every single Palestinians death, including the death cause by their own firing.
The situation in west Bank is qualitatively the same.
No, protecting your people from terrorist is not apartheid, and Israel has no interest to build iron beam and/or build wall--which the west misinterprete as apartheid-- if the neighbors had no intention to eliminate them.
The issue with that type of reasoning is that if you swapped the parties the sentences would be the same. "Palestine removed generations of settlements from Israel, but was forced to attack because Israel wanted to wipe them out." You need to think in terms of principles that can apply equally to everybody.
There are 2 million muslims living in Israel.
There are zero Jews in Gaza -- not even just living ones, they had to remove the long-buried dead ones too.
Iron Dome, Iron Beam… what next, Iron Curtain?
https://en.wikipedia.org/wiki/Iron_Curtain_(countermeasure)
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.
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
100 kW. That's a lot. I wonder how many kW will be needed to save them from God's wrath
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.
I wish they would make a demonstration
It’s disappointing to keep being shown that if HN was around in the 40s, it would overall be condemning the Warsaw ghetto uprising and arguing all those living there should be further punished.
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)
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.
