It is reported that the United StatesB-21 "Raider" bomberThe successful completion of its maiden flight on the 11th of last month marks the entry of the aircraft into the "ready for service" stage and is currently undergoing final test work. This news has attracted widespread attention, especially in the United States and some politiciansb-21withChina and RussiaExistingThe contrast, as well as the lead it showed, has been extensively reported and commented on. The American manufacturer Northrop Grumman even declaredb-21It is the world's "first 6th generation fighter" and represents the air combat of the United StatesManufacturingA major breakthrough in the level. However, at the same time, it was also pointed outb-21The cost of construction is still expensive, and it is expected to cause some dissatisfaction from the outside world. At present, the overall cost of the public procurement of the project is 246 billion US dollars, but the specific purchase quantity is not announced, so it is impossible to estimate the unit price, which is expected to be between 80 and 100 aircraft. Considering that the cost of building a single frame is already more than $700 million, it is foreseeable that the cost of procurement will be even more expensive. While members of Congress are unhappy about it, some people are trying to publicize itb-21It's an unthinkable super, claiming that Russia and China cannot detect it. However, the Russian news agency Sputnik interviewed RussiaMilitaryExperts,MilitaryAlexander Mikhailov, director of the Bureau of Political Analysis, he forb-21As well as the statements of parliamentarians who expressed their views.
Alexander Mikhailov was the first to noteb-21And did not reach the same level as the predecessor B-2BombersMore successful goals. In his opinion, the same faces the problem of higher construction costs, if oneb-21With a budget of $700 million to $800 million, it is not much different from the B-2. Therefore, the parliamentarians tried their best to exaggerateb-21RightChina and Russiathreats, and claimsChina and RussiaIt is not possible to cope with this new style, mainly due to:b-21The cost of construction is high. However, Mikhailov noted that Russia has several of themMeter-wave radarstation, capable of easily identifying stealth aircraft, hypersonic at a distance of up to 600 kmand general flight equipment. Ifb-21In contrast to the B-2, there are no "technical innovations", and they will be detected by the fighter's airborne radar and ground system radar at this distance. Judging by the current indications,b-21And did not go beyond this, so it is difficult to pose a threat to Russia. Mikhailov also said that China is also equipped with a similar radar system, and there is no evidence of thisb-21Can be avoidedChina and Russiameans of detection and surveillance. To sum up, according to the data published so far,b-21In addition to some differences in the exterior layout (such as wing design, air intake and fuselage structure, the size of the cockpit window, etc.), the B-2 only uses a "new generation stealth coating" in terms of the most critical stealth material. Therefore, it can be inferredb-21Still inChina and RussiaWithin the detection range of special radars.
b-21BombersThe design and R&D representedU.S. Air ForceAn important breakthrough in power, although some experts consider it expensive to build, does not negate the value of the aircraft at the strategic and tactical level. First of all,b-21Possess the ability to surprise and strike at the enemy. Secondly,b-21AdoptionStealth technology, which can maintain low observability under enemy radar surveillance, allowing for greater superiority on the battlefield. In addition,b-21It also has long-range strike capabilities, which can quickly reach targets far from the base and maintain long-term combat capability. These features make it:b-21It has become a powerful strategic strike platform capable of effectively performing a variety of tasks, including striking the enemy's vital targets and supporting ground forces.
However,b-21There are also some challenges. First of all, expensive construction is a problem that cannot be ignored. The high cost of construction will have a direct impactb-21and the subsequent maintenance and guarantee costs. Secondly, as technology continues to evolve, rightStealth technologyThe breakthrough and the upgrade of the enemy's radar system may makeb-21's stealth ability is challenged. In addition, with China, Russia and other countriesMilitaryTechnological advances, and new means of defense may emerge in the future, rightb-21poses a greater threat. Therefore, the United States should further strengthen its controlb-21technology update and R&D investment to improve its survivability and combat effectiveness in complex battlefield environments.
important as two other great powers in the worldMilitarypower, Russia and China rightb-21's detection and response technologies are of great significance. According to RussianMilitaryThe opinion of the expert Alexander Mikhailov, Russia has several seatsMeter-wave radarstation, which can easily identify stealth aircraft, hypersonic, at a distance of up to 600 kmand general flight equipment. The presence of these radar systems makes:b-21Becomes easily detectable when entering the range and does not pose much of a threat. Similarly, China is equipped with a similar radar system, which is also equipped with the right onesb-21Ability to conduct detection and surveillance.
Mikhailov noted that ifb-21Without a technical innovation to the B-2, it will be difficult for it to avoid detection by these radar systems. Current indications show thatb-21The B-2 is not surpassed in stealth, so it will not be very difficult for Russia and China to detect and monitor it. By having these radar systems, Russia and China can better copeb-21and take appropriate defensive measures. Therefore,b-21It's not something that is completely undetectable and undetectable, the degree of threat has yet to be verified on the actual battlefield.
