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 first flight was completed at Lockheed Martin's Advanced Development Programs facility (Air Force Plant 42) in Palmdale, California on June 2, 2009 by the Air Force Research Laboratory in conjunction with Lockheed Martin. [5] In October 2009, the ACCA demonstrator was designated X-55A by the USAF. Over the course of the program, 15 to 20 ...
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.
The CL-1201 design project studied a nuclear-powered aircraft of extreme size, with a wingspan of 1,120 feet (340 m). [4] Had it been built, it would have had the largest wingspan of any airplane to date, [5] and certainly more than twice that of any aircraft of the 20th century.
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 ...
The Lockheed XF-90 was built in response to a United States Air Force requirement for a long-range penetration fighter and bomber escort. The same requirement produced the McDonnell XF-88 Voodoo . Lockheed received a contract for two prototype XP-90 s (redesignated XF-90 in 1948).
A twin-tailed B-25 Mitchell in flight. A twin tail is a type of vertical stabilizer arrangement found on the empennage of some aircraft.Two vertical stabilizers—often smaller on their own than a single conventional tail would be—are mounted at the outside of the aircraft's horizontal stabilizer.
The X-44 was designed by Lockheed Martin to demonstrate the feasibility of an aircraft controlled by vectored thrust alone. The X-44 design had a reduced radar signature (due to lack of tail and vertical stabilizers) and was made more efficient by eliminating the tail and rudder surfaces, and instead using thrust vectors to provide yaw, pitch ...
