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 ...
Three variants were designed: the F-35A (conventional take off and landing, CTOL), the F-35B (short-take off and vertical-landing, STOVL), and the F-35C (carrier-based catapult assisted take-off (CATOBAR), CV). Despite being intended to share most of their parts to reduce costs and improve maintenance logistics, by 2017 the design commonality ...
the rear of the F135 engine (nozzle rotated down) that powers the 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 ...

Two F-35B Lightning II aircraft landing onboard HMS Queen Elizabeth in 2018. Shipborne rolling vertical landing (SRVL) is a method used to land a V/STOL aircraft that uses both the vertical thrust from the jet engine and lift from the wings. A V/STOL aircraft normally either lands vertically or it makes a conventional runway landing.
