    I’ve been wondering why they weren’t using nets to intercept drones. Hitting a flying object with another flying object is very hard, but a big net blocking a big area where a flying object will likely fly thru should be relatively much easier. And if the netting alone isn’t enough to disable the drone/missile then electrify the net to electrocute it

      Many of the high traffic roads are covered with nets. It’d just require an absurd amount of netting to actually block off a city or something, and it’d be effectively impossible to electrify it.

          Oh, I think you’re right. I read using a big net to stop them meaning surrounding the thing you’re defending with a net. I guess they meant firing one. The reason for that is pretty simple: drag. A big net would have a ton of drag, so it wouldn’t fly far. You could have a missile that ejects a net to catch a target, but nets also weigh a lot and you could instead have a bunch of pellets, fragmentation, or something. There are uses for nets, like the drone video in the OP, but they have some serious limitations too.

      They do use nets, sometimes shotguns too. I think the main reason they don’t more often is it’s a lot easier to fly within a few feet of a target and explode then it is to aim a net, usually outside the vision of the camera

      i wondered the same but figured that shooting a net while flying high speeds is more difficult than just peppering an area with shrapnel.

        I think shrapnelling like that is actually very hard to do at scale. You have to have a zillion big mortar guns dotted everywhere along possible flight routes, you have to protect the big guns from being blown up themselves because they’re easy juicy targets, you have to calculate specific trajectories every time you take a shot, you have to take multiple shots to have a reasonable chance of hitting it, but each shot requires like 10 seconds to reload after which the drone is now very far away, you have to be able to consistently deliver large stockpiles of ammunition to every gun on the front lines and elsewhere, and more.

        But with net-deploying drones, the drone can just fly into the general area of the incoming projectile’s flightpath and hold up a big like 10x10 meter net that the incoming projectile has no chance of avoiding
