This whole issue goes back a decade or so, notably the disjointed way MoD embraced UAVs. I recollect that DAS got himself a UAV SO1 desk officer who spent a deal of time trying to figure who had their fingers in the various pies across the three services. The resultant wiring diagram was a a bowl of spaghetti, it being obvious that the three services were going-it alone.
Slightly smugly, it is good to see that Reaper is delivering; the RAF do Air Power.
