The company draws upon the rich history of the former Lockheed and Martin Marietta corporations. While the formation of Lockheed Martin in 1995 was a merger of equals, by far the greatest contribution to Lockheed Martin Aeronautics was the product portfolio of Lockheed. This included the C-5, C-130 and C-141 transports as well as the F-2, F-16 (purchased from General Dynamics), F-117, F-22 and F-35 Lightning II.
The most important project by far to Lockheed Martin Aeronautics is the F-35 Lightning II (JSF). Worth a potential $200bn the initial order book is approximately 3,000 excluding almost guaranteed export orders. The F-22 air dominance fighter, while smaller in terms of aircraft ordered, is still of great importance to Lockheed Martin (and partner Boeing).
