That contract was first awarded to Airbus' A330-MRTT tanker aircraft (which is currently in service with other air forces). Boeing was so upset by losing a Pentagon contract that they lobbied the US government hard into voiding the original contract award and re-opening the tender. Subsequently, Boeing placed an unreasonably low bid and Airbus walked away saying they can't make it happen at that price. So, this was an entirely predictable own goal by Boeing.
