SURELY the US is working on a DRONE SHIELD. It shouldn’t be that hard.
US ground forces have a wide range of anti-UAV tools.
For instance, the Army/DoD has adapted the 30mm chain gun from the Apache helicopter for ground and wheeled vehicle mounts. It has a longer barrel and improved anti-jam features plus ‘special’ optics and sensors for tracking, identification an targeting. Can be mounted on a M998Humvee using the CROWS (the remote mount on the roof controlled by a soldier or Marine inside using a ‘nintendo’ console.) Can also be mounted on an F-250, creating an anti-drone ‘technical.’ The M998 mount can also me loaded with HellFires for those who need the very best ;-)
The special sauce of this tweaked 30mm gun is the proximity-fused munition. The shell detonates when close/close enough to the ‘drone’ to disable or destroy it. Works REALLY well - saw it tested live.
ALSO some forces are fielding a shoulder-held ‘EMP’ gun that is aimed at a visible target, debilitating it with directed energy of the right wavelengths. Looks like a Stinger had a baby with several enclosed small Yagi antennae.
Lastly there are longer range anti-air small-theatre missile systems that can take out the higher fliers.
The US military is *DEEP* into using a WIDE range of UAVs and we understand the technology and the missions quite well. We also know how to kill them...
Also the US Navy has signed off on a 30 kW laser-based system that’ll kill targets ranging from drones to patrol craft.
Deployed on a couple ships in the Persian Gulf. Tested there as well on the Ponce - To make sure the ‘bad guys’ knew it was actually a thing.
Takes a LOT of power (go figure) so ships make sense.
A true anti-materiel death ray.
