Given the Air Force’s wide-ranging needs and budget constraints, a dual buy of new tanker aircraft isn’t viable, Air Force Secretary Michael Donley told the House Armed Services Committee Tuesday. “This would be an expensive way to proceed,” he said. The Air Force plans to award a singled KC-X tanker contract later this year and then procure about 15 new airframes annually from that supplier until the 179-aircraft recapitalization is complete. If there were two suppliers, then “the minimum economic order for each line would probably be about 12 aircraft,” meaning the annual buy would jump to 24 tankers, Donley explained. Not only would that be “very inefficient,” it would also cause “a big bump” in the service’s budget and divert funds from other priorities. “We have to manage this procurement in the context of all other things that the Air Force is doing,” he said.
The Air Force has embraced new technical approaches like open mission systems and rapid software updates for cutting-edge aircraft like the B-21 and Collaborative Combat Aircraft. Increasingly, though, the service is also working to apply these to its older, “legacy” aircraft, officials said this week.
