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.
Hmm interesting. Imagine a new arms race between lasers and drones. Country A can make this crazy laser defense system. Country B can make 50x as many drones as country A can handle.
