So far, the F-35 has three models, the F-35A with traditional runway take-off and landing, the F-35B with short take-off and landing vertical take-off and landing, and the F-35C as an aircraft carrier. The F-35 is a fifth-generation fighter with a stealth design, a combat radius of more than 1,000 kilometers, no supersonic cruise capability (the afterburner needs to be turned on to achieve supersonic speed), and no vector thrust on the engine.

R&D history. The F-35 was developed on the basis of the X-35 demonstrator, which won the American JSF fighter program. The U.S. military expects the F-35 to form a high-low match with the F-22 fighter.

On 26 October 2001, US Secretary of Defense Air Force Roshi announced that Lockheed Martin's X-35 program had finally defeated Boeing's X-32 program, a powerful competitor, based on its strength, the advantages and disadvantages of its design, and the degree of risk, and had won the largest arms contract in history.
