F-35 Lightning II Joint Strike Fighter

Carrier based variant of the F-35C in flight with the US Navy

F-35 Lightning II Joint Strike Fighter quoted as the largest global defense programmed in history. It was a major multinational program to developed and produce affordable stealthy multirole fighter aircraft. F-35 JSF developed in 3 variants, F-35A conventional version developed for US Air Force & others participant countries, F-35B Short Take-Off Vertical Landing (STOVL) for US Marines & British Royal Navy & F-35C conventional carrier launched version for US Navy.

Origin named of Lightning II was after the P-38 Lightning (Lockheed Martin) & English Electric Lightning Jet. It was developed & produce by Lockheed Martin Aeronautic Corporation as Lead Integrator& manufacturer (surveillance & targeting System, weapon interfaces) BAE System (UK) for aft fuselage lead, Electronic Warfare System & HMSS (Helmet Mounted Symbiosis System), Northop Grumman for APG-81 AESA radar, DAS 360 degree sensors, communication, navigation & identification avionics & software.

United Technologies Pratt & Whitney involved in designed & developing F135-PW-100 turbofan engine (F-35A & F-35C) & F135-PW-600 turbofan engine with LiftFan & rotating nozzle (F-35B). Others company involved in developing F-35 including Martin Baker (ejection seat), Rolls Royce (F-35B LiftFan), Stork Fokker (wiring system), VSI (Rockwell & Elbit) (Helmet-Mounted Display System) & General Dynamics (25mm Gatling gun & cockpit display).

It's development partners participation divided into 4 Tier. For Tier 1, involved in design and development, US & UK participated. For Tier 2, involved in significant investment of F-35 program, Italy & Netherlands fill this tier. Australia, Canada, Denmark, Norway & Turkey can catogery in Tier 3 , for ordering commitment of F-35.

Singapore & Israel participate in Security Cooperation Partners. Israel commits to order 20 F-35i with option for another 75 planes in future. Singapore still did'nt commits any F-35 order in near future.

Japan become the first export customer for F-35A with 42 F-35A's order.

It's stealth designed as an affordable stealth multirole for air-to-air and air-to-ground mission. F-35 larger single engine without supercruise and supermaneuverability and less stealthier compare to F-22 Raptor. It was designed for 'low-observable' stealth when viewed from the front and less stealth to radar looking from sides & rear aircraft.
