Wouldn't it also be sensible and cost-effective to base the P8s at Kinloss, with the REs remaining there as a lodger unit? Loads of space for Joint Warrior, long runway, simulator, BFIs, maritime-related accommodation, new-ish sqn HQs and it would provide a DIV for Lossie. Inverness Airport has recently agreed to act as DIV for armed Typhoons and the natives are nervous!
