The backbone of America’s air superiority are the tankers and cargo planes of Air Mobility Command, headed by Selva. With 54,000 individuals and hundreds of aircraft, Selva still needs to balance modernizing a dangerously aging fleet while deciding whether legacy platforms such as the KC-10 will become budget casualties. One good sign: The KC-46 tanker replacement program is on track and has been protected from sequestration. Selva, who took over the command in November 2012 following a stint as vice commander for Pacific Air Forces is the senior-most officer to have spent a tour as one of Andrew Marshall’s (No. 14) military assistants.
