Fleet wide aircraft readiness rates have remained consistent over the last two decades, but not the cost to operate and maintain the aircraft. “Our costs have increased pretty significantly just to attain those mission capable rates,” Faykes said. In the last decade alone, said Faykes, the cost to maintain readiness climbed 87 percent. An older fleet is requiring more and more money to keep in the sky.
The United States Air Force is flying less than historic norms and funding for acquisition and readiness is on a path to further hollow out this too small and old force to that is incapable of sustaining an enduring combat air campaign.
