I think NATO missed out a few years ago, the AN
-124 people offered to NATO a R/R engined, modernised western avionic equipped, new production version.
It would have made sense to buy say about a 12-20 of them, in a manner similar to the AWACS buy in the 1980's, spreading out costs and sharing manning and use, which has worked for over 20 years with the E-3 fleet.
However, apart from it seems maybe a buy of a couple of C-17's by the Dutch, as well as the 5 RAF versions, it is hard to see any more beyond that.
A400M is not meant to be a C-17 rival, it will however carry more than the C-130J, like the LM
product will have in flight refuelling-as well as carry fuelling hoses.
Not the perfect answer for tasking beyond tactical stuff, but an affordable one.
At least A400M will provide a big improvement on all those older C-130s and C-160s.
