The F-35 Lightining II Program (also known as the Joint Strike Fighter Program) is the Department of Defense's focal point for defining affordable next generation strike aircraft weapon systems for the Navy, Air Force, Marines, and our allies. The F-35 will bring cutting-edge technologies to the battlespace of the future.
The JSFs advanced airframe, autonomic logistics, avionics, propulsion systems, stealth, and firepower will ensure that the F-35 is the most affordable, lethal, supportable and survivable aircraft ever to be used by so many warfighters across the globe.


 
The F-35 is developed, produced, and supported by an international team of leading aerospace companies. Lockheed Martin is the prime contractor, continuing its 100-year history of aircraft research and design with the Lightning II. Principal partners Northrop Grumman and BAE Systems build the center and aft fuselages, respectively. Northrop Grumman also brings its expertise in carrier aircraft and low-observable stealth technology to the F-35 program and supports logistics, sustainment, modeling and simulation and mission planning. BAE Systems contributes a rich heritage of capabilities, including short takeoff and vertical landing experience, advanced lean manufacturing, flight testing and air systems sustainment. Pratt & Whitney builds the F-35's F135 propulsion system, the world's most powerful fighter engine.
