The MRTT, like the A330, carries all its fuel in its wings. It cannot trade payload for additional fuel.
The KC-46 has belly tanks. It can trade payload for additional fuel in those belly tanks.
The result is that the KC-46 has a ferry range advantage over the MRTT.
Do you believe the stuff you spouting?
