The USAF has been playing with a new toy – a twin-mirror relay system that could be used for redirecting laser beams onto distant targets on the ground and in the air. The main advantage of this system is that it removes the need for the firing station to have line-of-sight on the target, and it is part of an ongoing plan to build a system of similar relays in space for missile defense and more. It’s a step on the ladder, but even the airforce themselves admit there’s a lot of work to be done yet.
