Was not one of the major incentives behind the A400 the larger freight bay to take the latest generation of vehicles with their greater mass and size?
Though the FRES programme has ballooned both in cost, and weight, so perhaps there won't be many of them, and those we do procure will be too large/heavy to fit in a standard A400? Have to hope that the Antonovs soldier on for a while, and that we stay on the same side as Ivan...
