I remember the time when the Australians would have happily walked away from the C-130J but the UK was so desperate we talked the Australians into staying with the project.
The problem common to both the A400M and the C-130J is the concept of building and certifying them as civil transports before turning them into military aircraft; it don't work, the manufacturers are clueless on how to do it and it certainly aint cheap.
BTW I like the sound of Atlas C Mk 1
