F-35 Lightning II
The F-35 Lightning II is the world’s most advanced 5th generation multirole fighter, bringing together stealth, agility and advanced technologies to provide the pilot with unprecedented situational awareness and unmatched lethality and survivability.

The U.S. Air Force, Navy and Marine Corps, as well as the U.K. Royal Air Force and Royal Navy, and military forces in seven other partner countries around the world will fly the F-35. The Royal Air Force and Royal Navy will purchase 138 F-35B aircraft, providing the UK with advanced technology, stealth capability and interoperability across military forces.

All three variants of the F-35 are currently flying and will continue to fly for more than 50 years. Lockheed Martin is currently delivering production aircraft to the U.S. government and international customers. With each flight hour and major milestone - including first flights, vertical landings and flights at supersonic speeds - pilots, customers and engineers learn more about the F-35 Lightning II.

The F-35 is developed, produced, and supported by an international team of leading aerospace companies. As the prime contractor, Lockheed Martin continues its 100-year history of aircraft research and design with the Lightning II. Principal partners Northrop Grumman and BAE Systems (a U.K.-based company) 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 programme 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. BAE is also responsible for the aft, fuel system, crew escape, life support and Prognostics and Health Management System, as well as the U.K. future carrier integration. Pratt & Whitney builds the F-35's F135 propulsion system, the world's most powerful fighter engine.

U.K. Involvement
The F-35 Lightning II isn't just a cutting-edge aircraft. It also demonstrates the power of collaboration. Today, a host of United Kingdom companies are playing their part in developing and building this next-generation aircraft and enhancing the U.K.'s ability to compete in the global technology marketplace.

The F-35 industrial participation programme is based on building global, best-value partnerships among industries in partner nations. The F-35 programme continues to create thousands of jobs throughout the country and contribute to the overall economic development of the U.K.
