actually space borne directed energy weapons have easier design envelopes than airborne. The beam energy from space doesn't need to be as intense to produce the equivalent destruction. far less atmospheric interference (typically far less than 28 atmospheric miles to target). yes, they have more than one in orbit. yes the beams co-focus. yes the beams are outside the visible spectrum. plus other sneaky stuff you never thought of...psst... SFL harmonic inter-modulation. they're decades beyond your comprehension. wakey wakey time. the real stuff doesn't get patented.
