A solid riposte KenV, but assuming the USAF were also very aware of all the points you made (base facilities, cargo capabilities, etc) it does beg the question as to why, when given the option, they chose the A330/KC-45?
The first competition did not include all these points. The KC-30 (which is what Northrop-Grumman called their A-330 based tanker) won. Boeing protested to the Government Accountability Office and forced a recompete.
The third competition (the second never got out of the gates) included all these factors. When all these factors were included, N-G saw the handwriting on the wall and pulled out of the competition. Airbus decided to go it alone and the KC-46 beat out the KC-45. Was Airbus's decision foolish? Sure, foolish like a fox. Airbus's proposal forced Boeing to completely redesign their boom and make other changes AND influenced Boeing to underbid the contract. Airbus's proposal had almost no chance of winning, but Airbus's proposal cost Boeing
dearly. In the long run, Airbus may come out ahead in all of this.
