This is a list of aircraft produced or proposed by the Lockheed Aircraft Corporation from its founding as the Lockheed Aircraft Company in 1926 to its merging with Martin Marietta to form the Lockheed Martin Corporation in 1995. Ordered by model number, Lockheed gave most of its aircraft astronomical names, from the first Vega to the C-5 Galaxy.
In order to take off, the plane required 182 additional vertical lift engines. These were similar to the engines from the Boeing 747, which was new at the time. Two variants were studied, a logistics support aircraft and an airborne aircraft carrier. There was a rumored third variant, but information on such a model has never been made public.
An increase of gross weight to 474,000 pounds (215,000 kg) is possible, with the heavier aircraft offered by Lockheed as -200I or -200(Improved). Saudi Arabian Airlines (Saudia) was a launch customer for the -200 series and operated a sizable fleet until 1998. A total of 24 L-1011-200 aircraft were built new, with the first delivered to Saudia ...
The vertical stabilizer is the fixed vertical surface of the empennage. A vertical stabilizer or tail fin [1] [2] is the static part of the vertical tail of an aircraft. [1] The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim ...
It also incorporated an unusual vertical stabilizer that could be moved fore and aft for horizontal stabilizer adjustment. Partly because Lockheed's design proved underpowered, it placed second to McDonnell's XF-88 Voodoo which won the production contract in September 1950, before the penetration fighter project was abandoned altogether.

The 1964 Savage Mountain B-52 crash was a U.S. military nuclear accident in which a Cold War bomber's vertical stabilizer broke off in winter storm turbulence. [3] The two nuclear bombs being ferried were found "relatively intact in the middle of the wreckage", according to a later U.S. Department of Defense summary, [4] and after Fort Meade's 28th Ordnance Detachment secured them, [5] the ...
[1] The Lockheed XFV (sometimes referred to as the "Salmon") [2] [N 1] is an American experimental tailsitter prototype aircraft built by Lockheed in the early 1950s to demonstrate the operation of a vertical takeoff and landing (VTOL) fighter for protecting convoys.
