The fourth generation fighter!
The F35 multi-purpose tactical attack fighter developed by Boeing Company and Lockheed Martin Company of the United States will use all fighter jets currently in service in the US military. Together with the F-22 fighter jets, it will form the high and low level of the new generation of US fighter jets. Match. ***There are three models: one is the aircraft carrier type (CV) that can take off from the Navy's aircraft carrier; the other is the conventional type (CTOL) designed for the Air Force that can take off and land at land airports; the third is A Vertical Takeoff/Short Landing (STOVL) version designed for the Marine Corps to quickly fly over hot spots. The three aircraft use the same engines and navigation equipment, and 60 to 80% of all parts are the same. According to the plan, approximately 5,000 fighter jets of the three types will be produced. The U.S. Air Force will purchase 1,783 aircraft, the Marine Corps will purchase 609 aircraft, the Navy will purchase 408 aircraft, and the British Royal Navy, which has invested $200 million in this project, will also purchase 150 aircraft. The price of a single machine is about US$30 million. The U.S. Department of Defense began bidding for the JSF project in 1996, and finally decided that Boeing and Lockheed Martin would each develop two demonstrator aircraft, numbered X-32 and X-35 respectively. On September 18, 2000, Boeing The X-32A demonstrator aircraft has begun test flights. The aircraft adopts an aerodynamic layout with a tailless delta wing and wing-body fusion, a V-shaped tail, and an abdominal air intake. On October 24, 2000, Lockheed Martin's X-35A demonstrator aircraft also conducted a test flight. The aircraft adopted a conventional aerodynamic layout with tilted twin vertical tails. Both the X-32 and X-35 use stealth technology, engines with a thrust-to-weight ratio of 10, thrust vector control technology, integrated avionics systems, active phased array radars and in-machine weapons bays. In 2001, the U.S. Department of Defense will select one of them to enter the engineering manufacturing development stage. According to the requirements, the JSF has an empty weight of 10.2 to 11.1 tons, an external load of 5.8 to 7.8 tons, a maximum level flight speed of Mach 1.4, and a combat radius of 1,300 to 1,575 kilometers.
