The latest B-21 "Raider" bomber of the United States made its first successful flight a few days ago and attracted much attention. However, the arrival of this fighter does not mean that China and Russia are completely incapable of confrontation. In fact, China and Russia have mastered some countermeasure technologies that limit the deterrence of the B-21.
First of all, the B-21 bomber was expensive to build, which became an important problem for it. According to reports, although the B-21 is advertised as a "6th generation fighter" and has some technical improvements, the unit price is still as high as 700 million to 800 million US dollars, which is not much different from its predecessor, the B-2 bomber. This high ** also limits the number of B-21s purchased and the scope of application, which may be limited in actual combat.
Secondly, the innovation of the B-21 bomber in stealth technology is not obvious. Although the US side claims to have adopted a "new generation of stealth coating", according to the available data, the B-21 and B-2 have not made much breakthroughs in the field of stealth materials. China and Russia have advanced radar technology capable of identifying stealth aircraft and hypersonics** at distances up to 600 km, so the B-21 remains within the detection range of special Chinese and Russian radars. China and Russia have established a number of meter-wave radar stations, which are capable of effectively monitoring and detecting this type of aircraft, making it difficult for them to pose a threat to China and Russia.
Russian military expert Alexander Mikhailov said that Russia has deployed a series of radar systems that can easily detect the presence of B-21 bombers. These radars are capable of detecting not only ground-based system radars operating in the centimeter-band of aircraft, but also stealth aircraft and hypersonics**. Similarly, China has similar radar technology, making it impossible for the B-21 to escape Chinese and Russian surveillance.
In addition to radar technology, China and Russia have also responded in other areas. Both China and Russia have developed their own stealth fighter programs, such as China's J-20 and J-31 fighters, as well as Russia's Su-57 fighters. These fighters have made great progress in stealth and performance, forming a certain balance with the B-21. In addition, China and Russia have also developed technologies such as hypersonic ** and anti-missile systems to maintain a certain advantage for themselves in strategic competition.
Although the B-21 has limitations in some areas, this does not mean that it does not have application scenarios. According to the experience of the United States, the B-2 bomber was mainly used to hit targets in small countries, and did not directly face large countries such as China and Russia. This also shows that the B-21 was limited by a certain framework at the beginning of the project, and the deterrence was controlled by formulating a clear target to strike. Thus, while China and Russia may be able to identify and monitor the B-21, it is still possible for the United States to use it to exert its might in specific situations.
In general, although the B-21 bomber is touted by the United States as a "6th generation fighter", its practical capabilities and deterrence have certain limitations. China and Russia have adopted a series of countermeasure technologies, which have limited the B-21's capabilities. However, the B-21 can still play a role in certain application scenarios. This also reminds us that any first-class system has its advantages and limitations, and its capabilities cannot be exaggerated, and it is necessary to comprehensively consider strategic needs and actual conditions. Only through the rational selection and allocation of high-quality equipment can we truly enhance the country's strategic security level.
