An area I am qualified to speak in....in the words of one of my first E-3 IPs, " why would the AF put a new engine in an old POS car? They are just going to run it till it totally dies, then go with some sort of UAV or newer/smaller plane like the BD700." Like others have said, we are the step-children of ACC, and the mission crew gets the toys. These engines drink gas! I was/am shocked at the burn rates compared to the KC135.
