          Maintenance focused

          The F404 is designed to maximize time on wing, simplify maintenance and keep Life Cycle Costs low. Its six-module engine architecture is reliable, easy to maintain and interchangeable. With no scheduled overhauls and on condition maintenance, the F404 maximizes engine availability.

          “This is all about joint warfighting excellence,” said Air Force Chief of Staff Gen. David L. Goldfein (retired) shortly after the selection of the new trainer. “We need the T-X (T-7A) to optimize training for pilots heading into our growing fleet of fifth-generation aircraft.”
