The UK has successfully fired a high-power laser weapon against an aerial target for the first time in a trial.
It is hoped that the test will pave the way for a low-cost alternative to missiles to shoot down targets like drones.
The DragonFire weapon is precise enough to hit a £1 coin from a kilometre away, the Ministry of Defence (MoD) says.
I wonder how they scale up. Probably not great since the amount of energy lost scales greatly as well, to the point where there’s so much heat it’s not possible to cool anymore.
