Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift and can also withstand afterburning temperatures in conventional ...
The F-35 was the product of the Joint Strike Fighter (JSF) program, which was the merger of various combat aircraft programs from the 1980s and 1990s. One progenitor program was the Defense Advanced Research Projects Agency (DARPA) Advanced Short Take-Off/Vertical Landing (ASTOVL) which ran from 1983 to 1994; ASTOVL aimed to develop a Harrier jump jet replacement for the U.S. Marine Corps ...
The Pratt & Whitney F135 is an afterburning turbofan developed for the Lockheed Martin F-35 Lightning II, a single-engine strike fighter.It has two variants; a Conventional Take-Off and Landing variant used in the F-35A and F-35C, and a two-cycle Short Take-Off Vertical Landing variant used in the F-35B that includes a forward lift fan.

The Lockheed Martin F-35 Lightning II is a family of stealth multirole fighters that first entered service with the United States in 2015. The aircraft has been ordered by program partner nations, including the United Kingdom, Italy, Norway, and Australia, and also through the Department of Defense's Foreign Military Sales program, including Japan, South Korea, and Israel.
The F-35 has had to develop a thick skin. From my former colleagues in Congress to defense-industry experts, the world’s premier fighter jet is accustomed to criticism for issues with cost ...
The potential sale of F-35 aircraft drew criticism with regards to maintaining Israel's qualitative military edge, a policy enshrined in U.S. law, as well as concerns regarding human rights violations during the Yemeni Civil War and Saudi Arabia's role therein. Additionally, concerns have been raised that procurement of the F-35 could spark a ...
Former RAND author John Stillion has written of the F-35A's air-to-air combat performance that it "can't turn, can't climb, can't run"; Lockheed Martin test pilot Jon Beesley has stated that in an air-to-air configuration the F-35 has almost as much thrust as weight and a flight control system that allows it to be fully maneuverable even at a ...
A Lockheed Martin F-35 Lightning II aircraft performing a vertical climb using its Pratt & Whitney F135 jet engine, which produces 43,000 lbf (190,000 N) of thrust. [1] Thrust is a reaction force described quantitatively by Newton's third law.
