On va dire que c'est de l'histoire

However, he conceded that one previously identified issue is proving harder to solve than Boeing hoped.
When the tanker connects its refueling boom to a large aircraft such as the big C-17 military-transport jet, unacceptable stress loads are applied along the axis of the boom. To solve this problem, Boeing had been testing a software fix that attempted to better synchronize the in-flight movement of the tanker relative to the receiving aircraft.
Boeing has now decided to modify the boom hardware because the software changes didn’t fix the problem.
The Pentagon cleared Boeing’s KC-46A aerial refueling tanker for Low Rate Initial Production (LRIP) after the aircraft completed Milestone C refueling tests.
All that remains now is for the US Air Force and Boeing to execute the contracts.
This is welcome news for Boeing and the USAF.
partially offset by a $243 million pre-tax charge on the KC-46 Tanker program primarily related to additional effort to incorporate previously identified changes into initial production aircraft.
Boeing is suing Able Aerospace Adhesives and AlfaKleen Chemical Labs for supplying a mislabeled chemical that caused the maiden flight of the KC-46 tanker to be delayed by a month.
... Pour l'USAF, grâce à la clause de prix fixes. Pour Boeing, je ne pense pas, puisque une succession de pertes a été enregistrée.Poncho (Admin) a écrit:Mais paradoxalement, il est moins cher que prévu...
Autrement dit, par la clause de prix et caractéristiques figés, l'USAF s'est protégée du risque habituel des programmes militaires : la modification en cours de développement de la configuration ou des performances exigées, source fréquente de surcoûts.Beochien a écrit:Lire page 10.
The Air Force has been able to decrease its cost estimate over the past 4 years primarily because it has not added or changed requirements and therefore there were fewer engineering changes than expected. According to program officials, the Air Force’s initial cost estimate included a large amount of risk funding for possible requirements changes, based on its experience with prior major acquisition programs. Military construction costs have also come in below estimates.
