The USAF has apparently filed its arguments rebutting Boeing's protest of the KC-X tanker selection - and they're pretty robust. Reuters has the scoop here on the document that the service has sent to the Government Accountability Office. Thanks to Scott Hamilton for highlighting it.
The Air Force's arguments basically fall into two categories: on some points Boeing should have complained during the competition, not now; and on others they're just not valid grounds. In particular Reuters reports it saying the issue of alleged foreign subsidies should have been raised during the competition - but anyway that was not the reason that Northrop Grumman's cost/price risk was assessed as better.
Elsewhere, Northrop Grumman has rounded up 22 retired Air Force generals to support the KC-45 selection - the Mobile Press-Register says at least nine are on the company's payroll one way or another. Jim Wallace at the Seattle PI says all 22 are in either Northrop or EADS' pay.
And Lt Gen Tom McInerney, USAF retd and now consulting for Northrop Grumman among others, has contributed a piece to Human Events.com rebutting an earlier article supporting Boeing.
