Common sense issues more like. At what point in the project did someone realise that EASA might not just happily certify a large UAS to operate routinely in what is fairly heavily populated airspace over a fairly heavily populated country?
Ducks not adequately lined up methinks.
There's an awful lot of civil / mil common ground to find before this whole UCAV/UAS thing becomes routine in places where you haven't got segregated and/or controlled airspace and mil controllers.....
As for ITAR, depends what they asked for. If I were US DoD, I'd be very reticent about letting anything to do with the control links to the system out of my very close hold..
