I'm thinking the same thing. You don't even need to fully destroy the drone, if you manage to damage the camera sensors or the exposed lithium cell it's game over for the drone.

How close are we to making a system that can have multiple counter measures autonomously deployed?

(1) if prop based, launch something to snare the props (2) if reflective, pre-launch something to spray black non-reflective paint at it, and followup with laser (3) if evasive, approach with random manouvers (4) if unknown, launch everything and see what works, and feed it back to the training data ... etc, etc.

Mirrors are not an effective defense against military lasers. The power levels are too high and dielectric mirrors only work over narrow wavelengths. In the specific case of US military tech, some of the platforms use white lasers such that even dielectric mirrors are pointless.

So the cartoons lied to me?

I would try a shotgun style subsonic load with an adjustable fin/spoiler system that can be calibrated relative to the range of the target. The projectiles fin would flare out to reduce speed as it approached the target. Then an explosive charge would release a spray of super glue or pancake syrup, or something to gunk up the mechanism or disrupt the airflow on the propeller.

It still takes few seconds per target with technologies available right now. That's likely the reason why an operational anti drone laser turret is not a thing yet.

> operational anti drone turret is not a thing yet.

I’ve read about a bunch of these systems even if they aren’t in widespread deployment some are still being tested in real world conditions.

What about: https://en.wikipedia.org/wiki/Silent_Hunter_(laser_weapon)

“The Silent Hunter has been used by Saudi Arabia to guard against Houthi drones and missiles.”

“During the World Defense Show in Riyadh the February 05, 2024, Poly Technologies announced the first hard-kill engagement of a one-way attack drone.[6]”

Again, it takes few seconds per target with current laser tech. Which means they don't have important simultaneous multi target engagement capability.

The targets, whether it's plumbing pipe rockets or lipo drones, come in at 100-1000 yards/sec, so you don't really have that many seconds per target.

They work in the demo in which you just shoot down the sole target as it fly perpendicular to the machine for both physical and career safety, but when it comes to deploying the thing around your bed, guns make a lot more sense.

The quotes suggest that system has actually been deployed and used successfully in real world conditions.

Also, your objection doesn’t really fit how drones have been used. Massive highly coordinated drone swarms are extremely unusual, the threat is mostly individual drones or small clusters.

Many very dangerous drones are well under 100y/s aka 200mph.

1000 yards/second aka Mach 2.7 is well beyond the ‘drones’ people are concerned with and into expensive missile territory. Which is where anti missile systems get used.

Maybe not completely, at least not for the camera sensors. If it has good enough initial targeting data - or a good enough last image from the camera - it may be able to find the target by inertial navigation from there (depending on laser range, of course).

Or miss by a long shot and hit a civilian instead.

It's extremely easy to make surfaces partly reflective and extremely hard to make lasers outside of labs more powerful.
Re:Ukraine's Autonomous Killer Drones Defeat Electronic Warfare by mattashii on Tuesday June 03, 2025 @08:50AM (#44169442)
More powerful than what? If StyroPyro can build handheld 200W+ LED laser device in his workshop [0], why wouldn't a sufficiently funded military be able to build an anti-drone laser with the same (or higher) power output?

Note that his laser burns through various reflective materials, including mirrors, copper, aluminium, and steel.

Burning stuff at 20 feet is much easier than burning stuff at thousands of feet in distance.

If a drone is 90% reflective it doesn't need a weapon besides your laser.. (If the star wars approach weren't a scam to enter an ever more expensive race as the side with more money than sense.)
