Two major companies were bidding for the replacement ship to replace the aging fleet of current tankers. The bid was won by the European Airbus company. The Airbus proposal was deemed to be a superior plane versus the Boeing bid. I can't fault the Air Force for wanting to get the most for their money.
I have to question some things about this and I think the award should be held up until it is better thought out. I have two concerns. First is that all things being equal, money spent by the government within the country is much better spent than money going out of the country. Even if more is spent, it still is money that creates jobs, tax revenue and a more robust economy. Second, the product needs to be adequate and meet the specifications of the bid. When the bid is between competing American companies, that is one thing. But when it is a choice between money staying in the country or exiting it, every aid to see that the American product meets the specifications should be given to the American company. In this case Boeing.
There is a bit of heritage to be considered too. Europe is a free Europe largely because of Boeing's bombers manned and supported by heroic American crews and built by Americans. Boeing is family and family comes first!
