The U.S. F22 fighter is known as the world's first fifth-generation fighter, and its unique design and advancement once made the United States proud. However, the United States made a serious mistake in judging the military situation at that time, overestimating its own research and development level, which led to the erroneous closure of the production line of the F22 fighter. They believe that the production of about 180 advanced F22 fighters is enough to meet the needs of the US military. However, this decision later turned out to be quite wrong.
China has been quietly carrying out research and development, and the emergence of the J-20 fighter has completely subverted American expectations. As China's first fifth-generation fighter, the J-20 not only has the advantage of surpassing the technical level, but also shocked the United States with its comprehensive combat power and outstanding performance in various data. The J-20 has a series of advanced features such as stealth capability, supersonic cruise capability, super-maneuverability and super information-based combat capability, making it the core combat power of China's fifth-generation fighter.
Although the F22 fighter is one step ahead in technology, with a number of patented designs such as butterfly wings, diamond-shaped air intake design, and excellent stealth performance, there are also design flaws, such as aging stealth coatings, which greatly weaken its stealth capabilities. In contrast, the J-20 fighter has made a major breakthrough in stealth coating technology, with its own patents and innovations.
The J-20's fuselage is 21 meters long, slightly longer than the F22's 19 meters, and its take-off weight and weight-bearing capacity also exceed that of the F22, allowing it to carry more combat readiness**. In addition, the J-20 has a combat radius of up to 2000 kilometers and a maximum speed of 2Mach 2, far more than the F22 of 800 km and 2Mach 0. These data show the advantages of the J-20 in a number of ways.
Although the J-20 is a new type of fighter, there are still some problems that need to be solved and room for improvement, but its late-mover advantage makes it have more room for improvement in design and construction. With the continuous development of China's aero engine technology, once the J-20 is fully replaced with a domestic engine, its combat power will be further improved, and it is likely to surpass the F22 and become one of the most powerful fifth-generation fighters in the world today.
Technically, the competition between the J-20 and F22 has become the focus of the global military field. Although the F22 fighter has accumulated rich practical experience in many years of flying, the J-20's late-mover advantage and continuous technological breakthroughs make it have greater potential in future development. This contest of fifth-generation fighters is not only a competition of technical strength, but also a manifestation of national strength and military influence.
