The F-35 is the result of the Defense Department's Joint Strike Fighter (JSF) program, which sought to build a multirole fighter optimized for the air-to-ground role with secondary air-to-air capability. The JSF requirement was to meet the needs of the Air Force, Navy, Marine Corps and allies, with improved survivability, precision engagement capability, and reduced life cycle costs. By using many of the same technologies developed for the F-22, the F-35 has the opportunity to capitalize on commonality and modularity to maximize affordability.
