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 F-35 Lightning II uses the Rolls-Royce LiftSystem, in which 29,000 hp [14] [15] [16] is diverted forward through a driveshaft from the engine's low-pressure (LP) turbine via a clutch [17] and bevel-gearbox to a vertically mounted, contra-rotating lift fan located forward of the main engine.
It was the first F-35 built at full production speed, and is structurally identical to the production F-35As that were delivered starting in 2010. [27] On 5 January 2009, six F-35s had been built, including AF-1; another 13 pre-production test aircraft and four production aircraft were being manufactured. [ 28 ]
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.

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 'power' of the F-35. The F-35 Lightning II Joint Strike Fighter is an advanced single-engine, multi-role strike stealth fighter jet made by American defense contractor Lockheed Martin ...
After a competition between the Boeing X-32 and the Lockheed Martin X-35, the latter aircraft was selected for a contract award and developed into the F-35 Lightning II, which will replace various tactical aircraft, including the US F-16, A-10, F/A-18A-D, AV-8B, EA-6B and British Harrier GR7, GR9s and Tornado GR4.
General Electric and Pratt & Whitney are fighting over the next F-35 engine. It's the most expensive defense program in history, so the stakes are high.
