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.

The Lockheed Martin X-35 was chosen over the competing Boeing X-32 primarily because of Lockheed’s lift-fan STOVL design, which proved superior to the Boeing vectored-thrust approach. The lift fan, which is powered by the aircraft engine via a clutched driveshaft, was technically challenging but DoD concluded that Lockheed has the technology in hand. The lift fan has significant excess power which could be critical given the weight gain that all fighter aircraft experience.

Lockheed Martin developed four versions of the Joint Strike Fighter to fulfill the needs of the Navy, Marine Corps, Army, Air Force and the United Kingdom Royal Air Force and Navy. All versions have the same fuselage and internal weapons bay, common outer mold lines with similar structural geometries, identical wing sweeps, and comparable tail shapes. The weapons are stored in two parallel bays located aft of the main landing gear. The canopy, radar, ejection system, subsystems, and avionics are all common among all different version as is the core engine which is based on the F119 by Pratt & Whitney.

Additional systems on the F-35A include:
Northrup Grumman advanced electronically scanned array (AESA) multi-function radar
Snader/Litton Amecon electronic countermeasures equipment
Lockheed Martin electro-optical targeting system
Northrup Grumman distributed aperture infrared sensor (DAIRS) thermal imaging system
Vision Systems International advanced helmet-mounted display

The Air Force expects that to purchase 1763 F-35As to complement the F-22 Raptor and replace the F-16 as an air-toground strike aircraft. The Air Force variant includes an internal gun, infrared sensors, and laser designator. This is the technologically simplest version of the JSF, in that it does not require hover or aircraft carrier capability. Therefore it does not require the vertical thrust or the handling qualities for catapult launches, augmented control authority at landing approach speeds and strengthened structure to handle arrested landings. At the same time, the Air Force F-35A will have to improve upon the high standards created by the F-16. Since replacement of the F-16 by the F-35A will entail a significant payload reduction, the F-35A faces a very demanding one shot one kill requirement.
