Strictly speaking, aerial tankers aren't considered combat aircraft. But for the better part of a decade, the U.S. Air Force's quest for a next-generation tanker had settled into a kind of bureucratic trench warfare pitting U.S.-based Boeing against the Europe-rooted EADS North America. Hostilities finally ceased in March after the Pentagon picked Boeing and EADS conceded defeat. Under a long-term arrangement that could eventually be worth $30 billion, Boeing will eventually build 179 new KC-46A tankers. (See the artist's rendering above, which also shows an F-35 approaching for refueling.) Among the selling points of the KC-46A, Boeing cites a "modern, digital flight deck" that's based on the electronic displays in its 787 Dreamliner.
