A word which I have yet to spot in this thread is 'convergence'. Does it not make sense to be heading on a convergent path with our allies when it comes to procurement? I can accept that the P 8 wasn't on the horizon when the procurement decision for the tankers was made, but is it really sensible to persist in ploughing a divergent furrow? Are we not in danger of being in a minority of 1 with drogue?
