Ah. Found; yes, probably @DARPA already had theirs, this one’s more (?) private-sector though: A partial solution to the Attack of the Drones thing.
Back some time ago I posted this gem, on a solution against drones, e.g., around objects of ‘vital infrastructure’ — that weren’t, like, so, about a hundred years ago and people may have been happier then.
Once drones were distinguished from birds [the in-the-air kind not the ones you spot on the beach, topless], any kind of mini-Goalkeeper preferably with buck shot (since short-range effectiveness is required only, without any long-range bystander damage risk) might suffice. I’d say Mini- indeed; more like a double-barrel pointed up above e.g., 50@deg; or more to prevent nasty fall-out on hoomans but with some swing capability to cross-fire.
The problem being, was, to have an installation small enough to be easily placeable in sufficient number to get good air dome/cylinder coverage but to not be too obtrusive. Yes, probably @DARPA already had theirs but didn’t want to beat the drum too much, to not lure ‘DoS’ swarm attempts or false-negative probing. But at least, for the rest of the World, there now is Elvira, instantly in fixed, flex as well as military versions.
Apparently, their aim is to prevent bird/drone collisions in mid-air (triggers association with this great clip work, and also this one) but I see use for the inverse, too, picking off the flyers/drones before they don’t, up against ‘vital infra’.
But aren’t we then reverting to an arms’ race where the silly, petty, may be stopped but not the countermeasure-escalation pro’s …? Like these:
[But hey, seems to be on a carrier exactly like I have in my back pond for fun and impressing the babes so can’t you have one, too ..?]
