The company draws upon the 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. Lockheed also supports its F-22 air dominance fighter in USAF service.
Lockheed C-141 StarLifter : First flown in 1963, the Starlifter is a strategic airlifter. The C-141 was produced at Marietta.
Lockheed C-5 Galaxy : The C-5 is the largest strategic airlifter in the USAF inventory and one of the largest aircraft in the world. The Galaxy was produced at Lockheed's Marietta facility and it is here that the current avionics and engine modernization programs are being undertaken.
Lockheed F-117 Nighthawk : The F-117 stealth aircraft is a product of Lockheed's Skunk Works. First flown in 1981, the aircraft has been put out of service in favor of the F-22.
Lockheed Martin F-16 Fighting Falcon : The F-16, which made its maiden flight in December 1976, was first developed and produced by General Dynamics. In 1993, Lockheed Corporation acquired General Dynamics' Fort Worth division, the production center F-16.

Lockheed S-3 Viking : The Viking was the US Navy's anti-submarine jet and also provided surveillance of surface shipping.
T-50 Golden Eagle : The T-50 is an advanced jet trainer produced by a partnership of Lockheed Martin and Korea Aerospace Industries (KAI). The two companies have formed the T-50 International Company for export marketing.
