Oh, yeah. I know we have shit for shooting down missiles and planes. This would work from a mid to high altitude aircraft to attack ground targets but, you would see the beam move as the aircraft traveled in relation to the ground target. This only gets more apparent the higher you go. Unless they have a few dozen satellites in geostationary orbits those beams will come in at a significant angle. Power is another issue. These lasers suck huge amounts of electricity. They either have orbiting fusion or fission reactors or they are using chemical lasers and even those need "refueled" from time to time. The system that you referenced also has a "spot" of only a few inches. These "beams" in most of the photos and vids looks 10s to 100s of feet wide. Given x amount of power output the more this is spread out the more power exponentially has to be used to get shit to burn. For a few feet wide spot you would need many megawatts. 100 feet or more would be terawatts of power per second of beam activity. I don't know what the fuck is going on with these fires but, an orbital DEW is unlikely yet not impossible. Lasers on drones?
