Adm. Michael Mullen says the decision to terminate the F-35 Joint Strike Fighter’s alternate engine program—a decision that prompted Congress to hold special hearings this week—was a joint decision between the Navy and the Air Force. (OK, but according to Air Force Secretary Michael Wynne, the idea originated with the Navy.) Mullen believes that technological advances obviate the need for an alternate engine source. He maintains that the reliability and economics added up to a savings of approximately $2 billion—the amount awarded to the alternate team of GE-Rolls Royce.
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.
