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 ...
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.

Aircraft such as the SR-71 Blackbird are designed to cruise at supersonic speed with afterburners enabled. Some fighter jets are capable of supercruise but only at high altitudes and in a clean configuration, so the term may imply "a significant increase in effective combat speed with a full weapons load over existing types".

The Rolls-Royce LiftSystem, together with the F135 engine, is an aircraft propulsion system designed for use in the STOVL variant of the F-35 Lightning II.The complete system, known as the Integrated Lift Fan Propulsion System (ILFPS), was awarded the Collier Trophy in 2001.
Because the F136 was designed well into the F-35's System Development and Demonstration (SDD) phase, it could better match its fan and core to the F-35 inlet, which was revised in 2005 to increase mass flow to 400 lb/s (181.4 kg/s) for greater thrust due to aircraft weight growth.
Japan announced plans to test F-35B stealth fighters on its new destroyer-turned-aircraft carrier. The testing, supported by the US Navy, will happen in October and November.
A U.S. Air Force F-35A Lightning II in flight. Operations of the Lockheed Martin F-35 Lightning II family began in 1995 with the Joint Strike Fighter program.Since its first flight in 2006, the aircraft has faced substantial controversy, shortages in its research and development supply, [1] and safety concerns due to incidents.
