I wonder if the system can double as an orbital weapons platform with global strike capability. They are talking about eventually scaling to megawatts of laser energy being fired into orbit then relayed back down to a target on the ground.
It's kinda weird seeing US military commanders pushing for tech to eliminate their reliance on fossil fuels. They are careful to avoid mentioning that this system is to replace the need for diesel generators at forward operating bases or jet fuel for drones. I guess that's because US political leadership has a different opinion on being dependent on fossil fuel.
I guess the real question then is whether or not it's easier for them to temporarily use a logistics asset or throw some gas and a lighter on a drone.
