Nurse,
Not sure about 3 ac types being C17,
Js and C17s again?? However, I do agree with your sentiments but write off the K at your peril as the beancounters will prefer it over the J every time. I think I've already said that with a fleet of 17s and
Js what more could you possibly want! As an aside, the Brits had the A400M contract re-written in order to stop the Germans 'pulling out', its now so watertight that we (the UK) are also committed 'till the bitter end even if we did want to pull out (which we probably do owing to the overwhelming success of the C 17)!!
In answer to your question, I believe that the wish is to operate 2 ac types in the tactical airlift role ie. perm any 2 from
Js, Ks, C17s & A400Ms.
