The point i was making you brought theoretical figure from wiki without any performance load factor while completely ignoring the capabilities and comfort level of much larger chopper. this evacuation mission surely among the longest mission and there is no evidence smaller choppers are used anywhere for similar duration mission. i would think US and allies in Middleast use US choppers much more extensively in Middleast and Africa than any European chopper. so the confidence on such systems is much higher and they surely are multifunctional. It is completely out of question that any European made or derived chopper will be used for such a mission. Germany had mentioned heavy chopper jointly built with France but they i think dropped it by now and now will have to pay as much as C-17 price.So you can imagine the amount of additional discrete fuel tanks required or even the prospects of necessitating IFR for it to make the 1600mi/2575km vs 1260km (630kmx2) as specced for the MH-47.
Expensive extra requests from Germany and inflation could raise the price to as much as 12 billion euros, the report said, adding that features such as aerial refuelling and special rotor blades were not yet available.
