Excellent, good excuse to scrap this one trick pony, save Sentinel and buy more P-8s!
For those with short memories, the UK AEW force was declared to NTO as our contribution to the NAEWF in lieu of paying for the rest of the force and contributing crews.
One presumes that, in their absence, we will be having to pay our fair share of the costs for the remainder of the force and its use. I doubt there are any savings, and with the remaining duplication in infrastructure it probably absorbs additional cost, not a saving.
