The first KC-46 delivery is not happening this October as planned

WASHINGTON ? The first KC-46 won?t be delivered this month as had been agreed upon by the U.S. Air Force and manufacturer Boeing, the service?s top civilian said Wednesday.

In an Oct. 17 interview with Bloomberg News, Air Force Secretary Heather Wilson acknowledged for the first time that the delivery milestone has slipped once again. Service officials and Boeing executives are meeting the same day to discuss how best to address a list of unresolved deficiencies ? one of the major barriers keeping the Air Force from accepting the new tankers.

Last month, Defense News first reported that two new category-1 deficiencies had been added to the KC-46?s list of problems, bringing the total to five. A category-1 deficiency is the most serious grade of technical issues that have no workaround in place.
