Unfortunately, what I have hooked up to my system is a rather pedestrian weather station, not the more interesting missile launcher. And yes, I know it just fires nerf darts or something like that, but I can still dream about an Anti-Air missile installation controlled via USB, can't I?
On the other hand, I doubt .mil publishes their interface specifications, and reverse engineering a missile launcher is likely rather expensive. Not to mention mildly dangerous..
