Default Blue Devil Airship is Getting a Super-High-Speed Optical Laser Downlink Upgrade

Would be nice to use these things for online gaming. A huge project reality server with allot of bandwith

The Air Force?s Blue Devil airship--a recent PopSci Best of What?s New recipient and a potential answer to the military?s expanding data glut problem--is getting yet another high-tech upgrade. Via a federal announcement put out last week, The Register reports that DARPA will outfit the Blue Devil Block 2 ISR airship with up to two Free-space Optical Experimental Network Experiment (FOENEX) systems. Think of them like optical lasers that move through the air with the fidelity of a fiber optic cable.

FOENEX taps adaptive optics technology--the same technology that lets terrestrial telescopes filter out visual noise from Earth?s atmosphere--to correct for distortions in the light caused by things like moisture and particulate matter in the air. They do so by measuring the distortions in a guide laser, then adjusting the receiver to compensate--down to one fifty-thousandth of a millimeter every millisecond. This basically gets rid of all airborne noise that can alter the stream of incoming photons in any way.

"Why do they even try to invade, why do they try to conquer? Why do they risk everything for such a small dominance? Because war is all they know, and without war they have no meaning for life, no meaning for the future. They are born into a world of such violence, and ignorance. The final battle is near, and their annihilation is at its peak. We are coming, and our numbers will darken your skies, you cannot run, you cannot hide.
