• The UK said it test-fired a laser beam weapon in a “groundbreaking” trial.
  • The Ministry of Defence said it could neutralize targets for just $0.12 a shot.
  • Countries are racing to develop weapons that can combat drones and missiles.

    I know, I know, Quora, but this seems properly researched.

    $0.23 for a round of 5.56, $0.76 for a round of 7.62. Ish.

    Keep in mind, too, that lasers fire in about as straight a line as you can hope for, while bullets do not. It’s going to take a lot more bullets fired to neutralize a target than laser “rounds” fired.

      And laser rounds have a velocity of the speed of light, so it’s pretty hard to miss if you have a perfect sight on the target

        I was thinking about potential for inaccuracy due to refraction from thermal inversion layers or other temperature anomalies, but then I realized that the refraction would equally affect the optics, provided that the optics remain on target throughout the firing.

          If I was designing a laser weapons system, I would probably include a targeting laser that would be of the same wavelength, and use that to automatically correct any alignment. A targeting laser, or series of lasers would require extremely tiny amounts of power compared to firing the laser weapon.

      In that case, when WW3 hits I guess I’ll use my toilet tank lid for armor

      Yeah… those figures might be outdated. Correct me if I’m wrong but isn’t 5.56 basically the same as a .223? If so Cabellas has them in a price range of $.60-$2.20/pc. Not that the price difference is what I’m correcting. What I intended to point out was that just because you can get ammo for $.23 doesn’t mean your actual cost is guna be $.23/pc. In my experience with cheap ammo you’re guna have at least 1 jammed per magazine on your best days. Unlike most things, you get what you pay for with ammo. I have 3 types of ammo for my AR. 1 cheap bulk box for making it rain lead at the range. 1 mid ranged box for actual use shooting coyotes, beavers and Coons. And the last ammo type are closer to the $2.20/pc price for when there is ever a scenario where I need to send 2 bullets through the same bullet hole from 500yds out. Lol half kidding but for real the bullet to bullet consistency for weight and concentricity of the $2.20 priced ammo to the .60 priced ammo is clear as day.

        Read the link. Those were rough prices for the military, and the poster admits that the prices are a little out of date. He’s not referring to what you’d pay at a sporting goods store.

            I read the whole thing about how much ammo costs at retail for an individual consumer.

        I can guarantee you’re not coming close to the bulk buy per-item discount the military gets
