We Have Only Bought The Lolly Not The Stick
Unfortunately, we have only bought the air vehicle and the sensors (to be paid for later from other project's money) and not the infrastructure to support the capability.
We are totally relient on the US and if we attempt to pay for the other LoD, particularly the communications links etc, the MoD will have to find another shed load of cash. If we do not do this and the US deny us the use of the links we end up with a fleet of expensive model ac.
I hope the introduction of UAVs will allow the Nim guys a chance to regroup and gets some home time.
