The Air Force estimate of $4.2 billion in savings over five years was unreliable and "may overstate or -understate the actual figure," the Government Accountability Office said in a preliminary report to Congress on the decision to retire the fleet.
Air Force leaders have said the service must retire the A-10 due to budget cuts in order to pay for the F-35A Joint Strike Fighter. Air Force Chief of Staff Gen. Mark Welsh has told Congress the A-10 is not flexible enough and the service can depend on a mix of other aircraft like the B-1, F-16 and F-15 to fulfill the close air support mission.....
-bth: This was a pretty calculated attempt by the Air Force to force congress to increase its budget to save the popular and necessary A-10. The thought that a B-1 could substitute for an A-10 is just insulting to Congress. Sadly PFCs and Lance Corporals die over issues like this and the Air Force could care less.
