Problems are persisting for the Boeing Co.’s new KC-46 tanker, but one aerospace analyst says the manufacturer isn’t in any danger of losing out on future orders with the U.S. Air Force. “These are short-term problems,” says Richard Aboulafia of Virginia-based Teal Group. “But there is no doubt about the outcome.” Boeing (NYSE: BA) is currently on contract to build 52 KC-46A Pegasus tankers for the Air Force, though the service plans to eventually buy 179 — with hundreds more potential orders in the future as it works to replace its aging fleet of refueling aircraft. The contract Boeing is currently on was won after a long and contentious battle for the job with Airbus.
