The B-21 bomber is a new generation of strategic bombers in the United States, known as the world's first 6th generation fighter. Despite being touted by the United States as a fighter with a leading edge, some politicians have questioned its and actual performance. Northrop Grumman claims that the B-21 is an improvement and upgrade on the basis of the B-2 and has the ability to mass-produce equipment.
However, Russian and Chinese experts expressed doubts about the performance of the B-21 bomber. They argued that the B-21 did not surpass the B-2 bomber's achievements, because it was too expensive. Once a B-21 costs more than $7-800 million, it doesn't make much difference compared to the B-2 bomber. The high cost of the aircraft is a concern for the U.S. Congress, which would require huge amounts of money to procure such a fighter.
While some U.S. lawmakers expect the B-21 bomber to be an invincible "peace," they claim that Russia and China simply cannot detect the presence of such a fighter. However, Alexander Mikhailov, a military expert in Russia, said that both Russia and China are equipped with meter-wave radar stations capable of detecting **aircraft**, hyperson** and conventional flight equipment. If the B-21 does not make a technological breakthrough, then its presence is easily detected by these radar systems. Therefore, the B-21 does not pose a threat to Russia and China.
In addition, Russia believes that according to the data disclosed by the United States, the B-21 and B-2 bombers, except for some differences in the appearance layout, only claim to use a "new generation of stealth coating" in the field of stealth materials. This means that the B-21 is still within radar detection range in Russia and China. Therefore, Russia ** is skeptical about the real performance of the B-21.
In response to the presence of B-21 bombers, both Russia and China have the corresponding technical means to respond. The first is the radar system, with both Russia and China building a number of meter-wave radar stations that can easily identify aircraft, hypersonics, and conventional aircraft at a distance of up to 600 kilometers. These radar systems are capable of operating in the centimeter-band and can effectively detect potential threats from fighters such as the B-21.
Secondly, China and Russia are also constantly researching and developing advanced technologies, trying to find ways to interfere and counteract. The core of the technology is to reduce the radar reflection cross section of the fighter, making it difficult to be detected by the radar system. Chinese and Russian researchers are working hard to find effective countermeasures through research on paints, special materials and electronic countermeasure systems.
In addition, China and Russia are developing anti-stealth technologies, such as penetrating anti-aircraft missile systems. These missiles can penetrate the defenses of stealth aircraft, attacking them. At the same time, China and Russia are also developing and deploying long-range precision strikes such as ballistic missiles and cruise missiles to improve their deterrence capabilities against enemy strategic bombers.
Overall, China and Russia have mastered a series of countermeasures against the B-21 bomber. The construction of radar systems and the development of technologies allow China and Russia to monitor the movements of the B-21 in real time and take corresponding countermeasures. At the same time, the research and development of advanced technology has enabled China and Russia to make certain breakthroughs in countermeasures. These measures ensure that China and Russia have a strong defense capability against B-21 bombers.
Although the B-21 bomber is officially advertised by the United States as an invincible strategy**, its actual threat has certain limitations. First, the B-21 is expensive to build and no specific quantities have been provided, which means that the cost of purchasing the B-21 will be a huge expense. This will put pressure on the U.S. team's budget and may limit its ability to purchase and deploy on a large scale.
Secondly, the stealth performance of the B-21 bomber does not constitute an absolute advantage over the radar systems of countries such as China and Russia. China and Russia have built a series of radar systems that can effectively detect B-21 fighters at close range. Although the B-21 has made some improvements in terms of exterior layout, stealth coating, etc., there are no breakthrough technological innovations. Therefore, China and Russia still have the ability to effectively detect and monitor the B-21.
Finally, due to the constraints of politics and international relations, there are often certain restrictions on the use of strategic bombers. In the case of the use of B-2 bombers by the United States, the targets are mainly relatively small countries. This suggests that the use of the B-21 bomber may also be limited by a certain framework, rather than being able to strike at any country at will. The Pentagon also did not publicly declare that the B-21 can ignore the detection of China and Russia, which may only exist in the fantasies of some lawmakers.
To sum up, although the B-21 bomber is regarded as a new strategic ** for the United States, its actual threat has certain limitations. China and Russia have mastered the corresponding technical means, including radar systems and anti-** technology, which can effectively deal with the threat of the B-21. At the same time, the deployment and use of the B-21 is subject to certain political and international constraints. Therefore, China and Russia can guarantee their own security and interests through reasonable defensive measures.
