In 1993, the Joint Advanced Strike Technology (JAST) program emerged following the cancellation of the USAF's Multi-Role Fighter (MRF) and U.S. ASTOVL was rechristened as the Common Affordable Lightweight Fighter (CALF) in 1993 and involved Lockheed, McDonnell Douglas, and Boeing. Lockheed's concept was a single-engine canard delta aircraft weighing about 24,000 lb (11,000 kg) empty. Air Force (USAF) and USMC a key technology explored was the shaft-driven lift fan (SDLF) system. Under one of ASTOVL's classified programs, the Supersonic STOVL Fighter (SSF), Lockheed Skunk Works conducted research for a stealthy supersonic STOVL fighter intended for both U.S. 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. 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. Main article: Lockheed Martin F-35 Lightning II development Program origins 1.5 Procurement and international participation.Air Force, Navy, and Marine Corps for several decades the aircraft is planned to be a cornerstone of NATO and U.S.-allied air power and to operate until 2070. plans to buy 2,456 F-35s through 2044, which will represent the bulk of the crewed tactical aviation of the U.S. The aircraft was first used in combat in 2018 by the Israeli Air Force. Air Force F-35A in August 2016 and the U.S. Marine Corps F-35B in July 2015, followed by the U.S. The F-35 first flew in 2006 and entered service with the U.S. The acquisition strategy of concurrent production of the aircraft while it was still in development and testing led to expensive design changes and retrofits. The program has drawn much scrutiny and criticism for its unprecedented size, complexity, ballooning costs, and much-delayed deliveries. Several other countries have also ordered, or are considering ordering, the aircraft. allies, including the United Kingdom, Australia, Canada, Italy, Norway, Denmark, the Netherlands, and formerly Turkey. Its development is principally funded by the United States, with additional funding from program partner countries from NATO and close U.S. The aircraft descends from the Lockheed Martin X-35, which in 2001 beat the Boeing X-32 to win the Joint Strike Fighter (JSF) program. The aircraft has three main variants: the conventional takeoff and landing (CTOL) F-35A, the short take-off and vertical-landing (STOVL) F-35B, and the carrier-based (CV/ CATOBAR) F-35C. Lockheed Martin is the prime F-35 contractor, with principal partners Northrop Grumman and BAE Systems.
It is also able to provide electronic warfare and intelligence, surveillance, and reconnaissance capabilities. The Lockheed Martin F-35 Lightning II is an American family of single-seat, single-engine, all-weather stealth multirole combat aircraft that is intended to perform both air superiority and strike missions.
