B-21 is specially built for China.
B-21 stealth strategic bomber is the first type of US combat target strategic bomber . It is planned to be put into service in 2030, with a number of more than 100 aircraft. Its purpose is to strengthen the United States' ability to deliver ammunition from the second island chain when the first island chain airport cannot be used.
According to the United States, with the advancement of the People's Liberation Army's long-range strike firepower, the US military base in the first island chain is already within the scope of our strike. It is necessary to consider launching an attack from second island chain or even further away. In this context, stealth strategic bombers are essential. However, there are only 20 existing B-2 strategic bombers, so the B-21 stealth strategic bomber was developed.
(B-21 production will exceed 100 aircraft)
B-21 aims at Dongfeng missiles and should not be underestimated by
0 The US Air Force believes that in the anti-intervention/denial environment, B-52 and B-1B have relatively limited value. They can only launch stealth long-distance missiles like JASSM-XR from outside the first island chain for attack. However, in this way, the missile requires flying thousands of kilometers to reach the coast of mainland China. These missiles are relatively easy to detect under the background of flat oceans. In addition, these missiles cannot detect and attack time-sensitive targets, such as the Dongfeng-21D and Dongfeng-26D anti-ship ballistic missile launchers.
Therefore, the task of the US military to the B-21 stealth strategic bomber is to penetrate the Chinese mainland air defense system and attack those solid targets; use its own detection system to detect, identify and attack targets such as Dongfeng-21D and Dongfeng-26D with the support of the C4ISR system. In addition, it can also use airborne electronic and optical reconnaissance systems to detect our targets, collect our situations, and use them as an ISR platform.
There are 4 ways to fight stealth bomber
We still attach great importance to the threat of US stealth strategic bomber. Anti-stealing aircraft is the top priority of our new three-fight three-defense and is also the most priority project. After entering the new century, we have developed a large number of anti-stealth detection equipment departments for stealth strategic bombers, and have formed a relatively complete anti-stealth detection system to improve the ability of the air defense system to fight stealth targets.
1. Anti-stealth detection capability:
[ radar ] is the main means to detect stealth aircraft . Modern stealth aircraft mainly target frequency bands above centimeter wave, and the effect is relatively poor for meter wave and below bands. China has successfully developed a variety of rice wave active phased array radars, which have good detection capabilities for stealth aircraft . Some radars have successfully detected the US F-22 stealth fighter in actual use and have conducted stable identification and tracking.
In addition, new system radars such as domestic sky wave, ground wave radar, , thin array, and passive detection have also made great progress. In particular, the domestic quantum radar has achieved long-distance detection of 130 kilometers. It is a powerful tool for detecting stealth aircraft. The development of these radars has further enhanced the ability of China's air defense system to fight stealth aircraft.
(domestic anti-stealth radar technology has matured)
2. Air defense interception. Seize air superiority
B-21 adopts a flying wing layout. The advantage of this layout is that its stealth performance is good and its disadvantage is also very obvious. That is, [mobility] is poor, and it cannot fly supersonic . Once is discovered, it is easy to intercept . Previously, the US Air Force adopted a method to provide escort for B-2 with F-22. Now the domestically produced J-20 stealth fighter has been put into service, and the number of equipment in 2022 has exceeded the F-22.
In terms of performance, J-20 can completely compete with the F-22. In this way, even if the US military dispatches the F-22 to escort the B-21, its safety cannot be guaranteed. The J-20 can also entangle the F-22 and let other aircraft intercept the B-21.
(The J-20 can complete the long-range raid interception mission, even if the opponent has a fighter escort)
3. Eliminate B21 on the ground
B-21 Another short-legged place is its range. The US Air Force initially asked the purchase cost of B-21 to be $550 million, which is only half of the B-2.Therefore, the B-21's payload, range and other indicators are lower than B-2, and its combat radius is only about 5,000 kilometers. This indicator is within the range of our medium and long-range missile strikes.
stealth strategic bomber has high logistical support requirements. B-2 can only be deployed in three bases around the world, and only , Guam can be deployed in this region. The guarantee conditions for B-21 are estimated to be much looser and can be deployed at more airports, but they are still a large aircraft, and the requirements are relatively high, and field airports are unrealistic.
Therefore, it is not difficult for us to obtain its base location. During wartime, we can use medium and long-range missiles and cruise missiles and to strike these airports, making it impossible for B-21 to use these bases, thereby weakening its combat capabilities.

4,
of course the most fundamental solution is [Develop our own stealth strategic bomber] . attack is the best defense . The biggest disadvantage of the island chain base is that the island area is limited, the material foundation is relatively weak, and it is difficult to deploy a relatively complete air defense system. In this way, there are many loopholes and gaps in the entire system.
If we have a stealth strategic bomber, we can counterattack and use the stealth advantage to penetrate the defense. We will come forward under the escort of the J-20 stealth fighter and future stealth carrier-based fighter jets, and strike the opponent's key nodes and targets in the first and second island chains, such as the B-21's base, and destroy them on the ground. Apply the same air defense pressure to the opponent, so that the opponent can also taste the taste of being bombed.
(Only by force and attacking strategy, only equal strength can one lose its troops without fighting)
Overall, after the B-21 stealth strategic bomber was put into service, it enhanced the long-range strike capabilities of the US Air Force, and we cannot take this lightly. However, the B-21 is not a beast. We have been prepared for its threats and have means to restrain our offense and defense.
