This is a grenade munition launched by rifle that can visually steer toward the optical behaviors of rotation. When we see vids of drones and the odd variation in quad propeller rotation due to operator inputs for steering and power, it looks like that gross optical cue would be easy to separate from
background and avian clutter. [As easy as face recognition?] Firing a special round in an M203 at the drone would be much more effective if the round had a little help at the very end of its flight.The current most successful method is using an expensive 20 or 30mm radar-aimed shell from a heavy, expensive IFV that might not be where it is needed. Or AA. Total overkill. Or just rifle. Total underkill. In addition the sensor is to be used in a simple proximity mode (sources of rotation getting further apart) to ignite the charge and spray the target cone with shrapnel. Nominally 40mm, the propellant charge would be much lower than standard, leaving plenty of internal volume for sensor and simple controls, as well as a healthy load of small, tiny shards.

Could be avoided by putting a grid of vanes below the propellers but that would add weight and reduce efficiency so [+]. Clever. |

It doesn't take much to bring down even a large hex- or octocopter, and I'm sure the operators have concocted some bob-and-weave tactics, so just a minor adjustment at terminal flight could make a difference. The small dji observation drones are the hardest to hit. IFV-mounted radar counter-drone systems brag about better than 90% hits within their long range. If you could get 15 or 20% hits each from 6-10 riflemen (not carrying any additional kit!) on a single target, that translates to high efficiency rivaling the best IFV scores and tons of drones shot down at the most critical time and place where they need to be destroyed. A rifle grenade solution at the squad level (probably not this one) will be a powerful counter measure. Can't wait to see. |

Might be good for current drones, but my guess is in the future the drone self defense will be quantity, a swarm of ten thousand drones is gonna need AI targeting I think. |

Maybe they swarm in at ground level, hugging vertical surfaces and stuff so you can't just blow them out of the sky with one big airburst. |

Crop-duster drone (large) spraying a coagulating pair (or whatever) of chemicals. Light-weight rotors + mucus = no fly. |

Or perhaps string/twine/synthetic stringy materials (Kevlar?) that would foul the prop(s) upon contact and resist cutting. |

I agree, [whatrock] - then after entangling the props, winch the lines back to bring the hunter drone into contact with its prey, using differential torque to attain the proper orientation and then deploy a small
* spray nozzle to paint over the victim's optics
* drill to attack the victim's fuselage
* soldering iron to muck up the victim's electronics
(choose or invent)
The more this ends up looking like a pair of crazed insects in a death match, the better I like it. |

@—2 fries shy of a happy meal
I really like this idea. Is a powerful enough pulse of EM possible from a 40mm grenade? I don't have the science to tell, but this would eliminate weight, maximize steering, increase power, range, etc. I think an explosion could be used to power the EM projector, but can it be focused? Does this type of weapon even need fine maneuvering at terminal flight?
@-lurch
The EMP 'battle' would end up looking less like a pair of crazed insect and much more like RAID sprayed on the loser. I prefer the crazed insect thing cinematically but I'm going for the certain victory of a democratic society over poor technology and authoritarianism. Let's do the crazed insect thing as a non-war project, own plans.Found this primer of Ukranian drone munitions: https://youtu.be/NjsemcB7I9o |

I've given it a bit of thought. |

When I saw the crowds of citizens in hang-kang all focusing lazer painters at dranes and fragging their aptics... I wondered ...what else fucks them up. Same with them robohounds. |

I'm used to dealing with real critters. Robo-critters is a whole new frontier. |

@ A1: Thanks for the link. Anything that includes an "explosively pumped flux compression generator" is tops in my book. Looks possible on a rifle grenade. |
