Terma ofĭenmark and Turkish Aerospace Industries of Turkey are supplying sub-assemblies for the centre fuselage. BAE Systems is responsible for the design and integration of the aft fuselage, horizontal and vertical tails and the wing-fold mechanism for the CV variant, using experience from the Harrier STOVL programme. Major subassemblies were produced by Northrop Grumman Integrated Systems at El Segundo, California and BAE Systems at Samlesbury, Lancashire, England. Final assembly of the aircraft took place at Lockheed Martin’s Fort Worth plant in Texas. The Lockheed Martin JSF team includes Northrop Grumman, BAE Systems, Pratt and Whitney and Rolls-Royce.

Lightning II Joint Strike Fighter (JSF) development More than 570 F-35 aircrafts were delivered by October 2020. Together, the UK Royal Air Force and Royal Navy intend to operate a total of 138 F-35B jets. The USMC will acquire 353 F-35B STOVL jets and 67 F-35C CV aircraft to replace F/A-18B/C and AV-8B, while the US Navy plans to procure 260 F-35C jets to replace F/A-18B/C and A-6, complementing the F/A-18E/F. The USAF has a planned purchase programme of 1,763 F-35A air-to-ground strike aircraft to replace F-16 fighter aircraft and A-10, complementing F-22 aircraft. A 70%-90% commonality is required for all variants. The JSF is available in three variants: F-35A, a conventional take-off and landing aircraft (CTOL) F-35B, a short take-off and vertical landing (STOVL) aircraft and F-35C, a carrier variant (CV). The single-seat fighter was designated the F-35 Lightning II in July 2006.

F-35 Lightning II joint strike fighter (JSF) is a stealthy, supersonic multirole fighter developed by Lockheed Martin Aeronautics Company for the US Air Force, Navy and Marine Corps and programme partners from the North Atlantic Treaty Organization (Nato) and US allies.
