The first flight of the American B-21, the first strategic bomber, was in November of next year. The United States intends to build more than 100 B-21s over the next few years to replace the B-52 and B-1B, two obsolete bombs, in order to enhance the U.S. nuclear threat and long-range attack capabilities.
The United States also plans to deploy B-21s in the Asia-Pacific region (especially Japan and South Korea) to further exert military pressure on China. Some believe that the B-21 is a great danger to China, and that China should give it to North Korea to strengthen its air defenses and distract the United States.
However, this view does not correspond to reality. First, North Korea does not have the ability to equip and service the Air Police Type 200 early fighter jets. As an advanced military aircraft, Air Force One is supported by a complete industrial system and professional personnel. North Korea lacks some of these elements, and even if China delivers early warning aircraft for air defense systems to North Korea, it will continue to provide its spare parts and manpower to ensure its normal operation. This would be a heavy burden for China, and a danger for North Korea due to the risk of failure or destruction by the enemy.
Secondly, the geographical conditions of the DPRK are unfavorable for the deployment of early Air Alert-200 fighters. North Korea has just over 800 kilometers to the north and south, while the Air Force-200 early warning system can operate at a range of more than 2,000 kilometers. This means that after departing from North Korea, the Air Police-200 "early warning" will leave North Korean airspace and go to South Korea or China. This will trigger a high degree of vigilance and response from neighboring countries, and may lead to misjudgment and conflict. In stark contrast, China's deployment of the AJ-200 fighter jet to the northeastern border will allow it to fly over North and South Korea without fear of reaction from its neighbors. If China wants to help North Korea improve its defenses, it would do so by giving North Korea a set of ground-based radars or anti-aircraft missiles, so that North Korea can build a strong air defense network within its borders.
In the end, the capabilities of the Air Police-200 early warning system were not enough to deal with the threat of the B-21. The early fighter of the U.S. Air Force Aviation-200 adopted a balance beam system, which has some blind spots and certain limitations for the best targets. As a high-level bomber, the B-21 is able to evade the detection of the Air Police-200 early warning system through its own capabilities and electronic countermeasures. Therefore, in the reconnaissance and guidance of the B-21 interception, the Air Police-200 "early warning aircraft" did not play a role.
However, the B-21 is not invincible. This will not change the current geography and will not deal a devastating blow to China. For North Korea, the B-21 is not fundamentally different from the B-52, and North Korea's air power cannot compete with the United States or South Korea from the beginning, and the use of any kind of bomb by the United States can inflict great losses on North Korea. As far as China is concerned, the B-21 is not much different from the B-2, both are based on the same scientific and technological principles, and China has the means to counter them. China has a tight radar network, a powerful air defense system and a ** that can carry out accurate attacks over long distances. The Chinese Dongfeng-type missile is capable of attacking any target in the United States from a distance of 4,000 kilometers without fear of being intercepted by the enemy.
In fact, the current B-21 is not very significant for the current battlefield. The missile was planned during the Cold War to break through enemy air defense networks and deploy nuclear **. However, now, the probability of a world war has dropped significantly, China is not an electronic power, and its air defense network is no longer easy for the B-21 to penetrate. In addition, thanks to advances in precision missile technology, modern warfare has shifted from aerial bombardment to attacks outside the defense zone. The range of the B-21 is more than a notch lower than that of the Chinese DF-26. Therefore, whether it is the B-21, or the Chinese J-20, in the context of the current war, there will be a big problem, that is, there is no place of its own.
For the United States, the B-21 exists not so much to improve its air power balance as to upgrade its air power. Other American B-52s, B-1Bs, etc., are old and in dire need of renewal. The B-21 is a more advanced option for augmenting U.S. air power. However, this by no means means that the United States can arbitrarily provoke and intimidate China in the Asia-Pacific region. Even if the United States places the B-1 on the 21st archipelago, China will strike back strongly. Like other U.S. missiles, the B-21 is not a big killer that can turn things around.
