F-35's irl information

The Lockheed Martin F-35 Lightning II is an American family of single-seat, single-engine, supersonic stealth strike fighters. A multirole combat aircraft designed for both air superiority and strike missions, it also has electronic warfare and intelligence, surveillance, and reconnaissance capabilities. Lockheed Martin is the prime F-35 contractor with principal partners Northrop Grumman and BAE Systems. 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 .

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 intended to replace the F-16 , F/A-18 , and the Harrier jump jet, among others. Its development is principally funded by the United States, with additional funding from program partner countries from the North Atlantic Treaty Organization (NATO) and close U.S. allies, including the United Kingdom, Australia, Canada, Italy, Norway, Denmark, the Netherlands, and formerly Turkey. Several other countries have also ordered, or are considering ordering, the aircraft. The program has drawn criticism for its unprecedented size, complexity, ballooning costs, and delayed deliveries. The acquisition strategy of concurrent production of the aircraft while it was still in development and testing led to expensive design changes and retrofits.
