"AND Airbus MRTTs (A-320)..."
I think not, old horseman. Airbus manufacture the world's only 21st Century AT/AAR platform, the A310MRTT - and the A330 MRTT for the RAAF is currently being built. The KC-30 for the USAF is also under study.
A320 would be a bit too small for any worthwhile AT/AAR application as the extra tankage to make it any use would severely limit its AT capabilities. But A321 as a single point centreline probe-and-drogue tanker could offer about 25 tonnes to fighter-type receivers over 90 mins on an AARA 90 min from the tanker base, landing with normal IFR reserves. With an additional 25000 litre fuselage tank over the wing, there would still be space for 116 passengers (48 in a front cabin, 68 in a rear cabin).
But even the CSA A400M would offer about 20% more fuel in the same scenario - and with 2 wing pods, of course - as well as space for 120 troops.
A400M is primarily a tactical airlifter with an additional intra-theatre AAR capability. A strategic tanker it is not!
D-IFF - if you want to work closely with the A330MRTT, PM me!
