still won't have made a decision on the Caribou replacement
I admit that the above are all a bit fanciful, except the last. With the double tandem landing gear the KC-390 will carry more and bigger stuff than a Herc with a lighter footprint that a C-27 into strips with 40cm potholes. This also makes it ideal for helicopter refuelling because it can provide that service where it is needed. It would be a bit embarrasing for the RAAF to bring the C-27 into service at the same time that less-developed nations are starting to operate something twice as good.
