South Korea is beginning the mass production of a low-cost laser weapon that has successfully shot down small drones during testing, the country’s key arms agency said Thursday.

The laser weapon, called Block-I, “can precisely strike small unmanned aerial vehicles and multicopters at close range,” a news release from South Korea’s Defense Acquisition Program Administration (DAPA) said.

The release did not give a cost for the weapon, but said each shot fired would only cost about $1.50.

Imagery supplied by the agency appears to show a weapon around the size of a shipping container with a laser mounted on top and what appears to be a radar or tracking device mounted on one side of the platform.

    There is no doubt that lasers will play a bigger and bigger role in combat systems, especially in a layered air defense networks.

    But it’s dishonest how these articles only cite the cost of electricity. It would be like citing the cost of a single shell of artillery to imply that is the only expenditure when the system is used.

    Just like a Howitzer, the parts on lasers experience wear and tear, but to replace them cost a hell of a lot more than a new barrel.

    Yes, in the long-term lasers will be more cost-effective than ground to air missile interceptors*, but any reporting that is clearly trying to make an argument for cost savings, should have the integrity to get figures that factor in battlefield maintenance of those systems.

    *When applicable. Lasers will not remove the need for any existing systems, but will provide a cost savings by providing additional options for the air defense system’s operators.

        The cost per round is a lot more than just power generation when talking about lasers.

        The wear on tear on lasers is a lot different than other systems and when the case is being made for their cost effectiveness they need to be factored in, instead of the highly misleading figures that only prices out electricity.

            it’s not just the laser…

            It’s the optics, it’s the cooling, it’s the physical mechanics it’s built on, the laser may be pushed well over it’s designed target range causing it to breakdown further.

            The power supply for the laser, the circuitry for control (to some degree) and most importantly, where ever you source that energy from. Presumably a super cap bank and a generator? Maybe batteries? Who knows.

                i would assume they used them in a heat sinking deal. Presumably to apply pressure to a diode package into a heatsink, while sinking heat, or something along those lines. Could be galvanic corrosion reasons also i guess.

              The mount would wear out, that’s true. As would the cooling pump, although I don’t see why you wouldn’t just use a cheap one off the shelf. The rest doesn’t theoretically need to wear if you make sure you have enough thermal allowances.

                yeah pretty much, optics would likely be pretty temperamental at those power levels, but maybe they aren’t using any? Idk.

                If a bug lands on one while it fires would basically melt the optics instantly. I would imagine.

          I mean, sure that’s fair, and the figures could be updated to include that. But the order of magnitude difference between this and explosive ammunition is 10,000x or more. Unless these are single fire, I’m not convinced it changes the calculus

        Even in the very long term, loss of equipment to enemy fire is non-negligible during active combat, so you need to tack on the purchase cost in some manner.

        In the shorter term you have to buy a 30 million dollar laser system, even if you’ll eventually make it back.

      Might still be powerful enough to blind the optics, which would effectively cripple them. Without a video feed neither FPV drones nor grenade-dropping ones would have the necessary precision to be effective.

          These lower power DEW systems don’t target the optics they target propulsion, like the actual rotors themselves. Takes about 1-2 seconds to knock them out on the ISR type drones, maybe a bit longer on the FPV type depending on size.

            I’d have thought the rotors would be harder to melt though because of their speed and cooling, but I guess it would work. Could you electroplate the rotors?

          GPS wouldn’t be effective at all for drones dropping munitions on infantry moving around on the battlefield, nor on FPV drones trying to fly into moving tanks or other vehicles.

          And how do you turn a drone away from an infrared beam of light that would damage the drones optics almost instantly? You’d have to spot the laser system from hundreds of yards away, recognize it’s aimed at your drone, and turn away before the laser is fired. And then what? Just avoid turning your drone back the way you want to go, hoping another strategically positioned laser you didn’t see doesnt fire from a different direction?

            You’d need to know where the laser system is, yes. You could do that by having a first done get shot at to reveal the position so the others know where not to look.

            Gps would still be effective against stationary targets, but gps jamming would probably be very effective.

        Depends on the wavelength. Standard mirrors don’t always do mirror things at wavelengths far outside the visible spectrum.

        Part of the advantages of UAVs is that you can deploy a lot of them cheaply with stuff you buy on eBay. While eBay does sell some of the more exotic mirrors for CO2 laser cutters (which are far-IR wavelengths), you couldn’t buy a lot of them to cover a single drone. It’d cut into the cost advantage, and would also weigh it down a lot.

          My initial reaction was that it’s going to make drones more cost prohibited. Logistics of only deploying unshielded drones where there aren’t lasers will probably be a thing now too.

        Even if they can, it will decrease the payload somewhat, and as the lasers get better the shielding will have to get stronger.

    Imagery supplied by the agency appears to show a weapon around the size of a shipping container with a laser mounted on top and what appears to be a radar or tracking device mounted on one side of the platform.

    So, 30 million for the setup and deployment but 1.50 per drone. Plus it is huge and unweildy.

    Gonna need a lot of drones to make that more cost effective than another drone with a stick or net, both of which have been effective in the defense of Ukraine.

    lol

    This is probably an early step towards a man portable setup so I’m just joking about the focus on the cost to fire.

          The Journalist targeted a drone at long range and burned through the body. Make the drone closer and select a less beefy component such as a rotor arm and they go down quicker. BTW if you didn’t catch it in the article maximum effective range is well over 1 mile.

          You also have to remember the US Military also isn’t going to allow a Journalist to publish the full capabilities of a fancy new future-tech weapon like this. Gotta leave some surprises in place!

    I hope this works how it sounds. The development of fighter planes, missiles and bombs, and drones has pretty grossly given an edge to invading militaries, able to quickly enter territory and do tremendous amounts of damage, especially to civilian life.

    Being a bulky, heavy weapon with a reliance on a lot of electricity should hopefully encourage this for defensive use, and if it can keep all those flying invaders in check this could be a boon against war.

    This is the best summary I could come up with:


    South Korea is beginning the mass production of a low-cost laser weapon that has successfully shot down small drones during testing, the country’s key arms agency said Thursday.

    The laser weapon, called Block-I, “can precisely strike small unmanned aerial vehicles and multicopters at close range,” a news release from South Korea’s Defense Acquisition Program Administration (DAPA) said.

    Future versions could be developed to take out much bigger targets, including aircraft and ballistic missiles, which would be a potential “game changer,” according to the release.

    DAPA will develop “a laser anti-aircraft weapon (Block-II) system with improved output and range compared to the current one,” the release said.

    In Ukraine, the Middle East and elsewhere, small drones - some available off the shelf - have shown the ability to disable or destroy multimillion-dollar pieces of military hardware, including tanks.

    Earlier this year, Britain showed off a new laser weapon that its military says could deliver lethal missile or aircraft defense at around $13 a shot.
