Although an MPA-based A400M with a single CBT would be able to meet all the in-theatre task need for 1312 Flt.
I think there is an obstacle to this idea in the FSTA exclusivity clause.
Let's see the A400M actually doing what we are buying it for before we think about using it as a solution to our tanker problem. It is showing all the signs of turning into another delayed, over-cost, Euro-political fiasco. How long before it reaches the same unit cost as the C-17?
At least we actually want the A330.
