The Air Force says it may retire a total of 272 aircraft in Fiscal 2008. This includes both fixed-wing airplanes and helicopters. Scheduled to go are: 17 B-52s, 24 C-130Es, 32 F-15s, 35 F-16s, 42 F-117s (completing the retirement of the Nighthawk fleet), 48 KC-135Es, 10 MH-53J/M helicopters, 63 T-37Bs, and one U-2. Originally, the service requested permission to phase out more than 300 aircraft in 2008. In Fiscal 2009, USAF has asked Congress for permission to phase out 182 aircraft.
As Air Force leaders consider concepts of operations for Collaborative Combat Aircraft, sustainment in the field—and easing that support by using standard parts and limiting variants—should be a key consideration, according to a new study from AFA's Mitchell Institute of Aerospace Studies.
