November 11, United Statesb-21"Raider" stealthBombersIn PalmdaleAir ForceThe base has completed its first flight, marking that the fighter has entered the "quasi-service" stage and is in the final test work. This one is known as:U.S. militarySixth generationBombersofb-21, with high expectations, was expected to continue the B-2 saga. And yet, right thereb-21Within just a month of the first flight,China and RussiaPlans for dealing with this new type of fighter were proposed, letU.S. militaryFeel uneasy.
b-21It's called "Peace."", with the characteristics of survivable, long-range and penetrating strikes,U.S. Air ForceExpectations are high for it. However, some experts say that although the B-2BombersVery effective when striking countries that do not have a well-developed air defense system, but when facing an enemy with a well-developed air defense system and anti-stealth tacticsb-21It is difficult to achieve a penetrating strike. A team from Northwestern Polytechnical University proposed in an article that in a war simulation, it was similarb-21of stealth platforms and their supporting facilitiesDronesShot down in the face of a Chinese air-to-air missile. And the Russian side announced the construction of several onesMeter-wave radarstation, which can easily identify stealth fighters, hypersonics, at a distance of 600 kmAs well as ordinary flight equipment. This makes:U.S. militaryRightb-21The performance of the cast cast doubt on the performance.
1. The U.S. military's challenge to hypersonic missiles and stealth technology
b-21The challenges are not limited to:China and Russiameans of defense, including hypersonic missiles andStealth technologydevelopment. In recent years,China and RussiaBoth have made great progress in the research and development of hypersonic missiles, which makes the traditional defense system face a severe test. In addition,Stealth technologyThe development is also constantly improving, the sensitivity and detection range of radar systems are constantly increasing, which is important forb-21Such stealth fighters also pose a threat.
2. The development trend of bombers and UAVs
In this day and age, simpleBombersIt has not been able to achieve outstanding results, and more and more countries have begun to pay attentionDronesTechnological developments. DronesWith the advantages of low cost, flexibility and no risk to personnel, it can play an important role in operations. In fact,DronesIt has shown its advantages in the Russian-Ukrainian conflict and has even been widely used in some civilian conflicts. China is also developing R&DDrones, if a group of hypersonic unmanned intelligent stealth vehicles appears in the future, it will be rightU.S. military's combat capability poses a great threat.
b-21Technical performance and cost issues are also issuesU.S. militaryChallenges to be faced. In modern warfare, it is difficult for a single fighter to achieve an overwhelming victory, and it is necessary to rely on the wholeMilitaryThe support of strength. U.S. militaryAlthough the high annual defense budget is large in terms of the total amount, the funds allocated to the various departments are not much. The military-industrial complex is contracted a large number of armament tasks, which leads to high costs. b-21The overall cost of the project is about $246 billion, and it is expected that no more than 100 aircraft will be produced, which translates to at least $700 million per unit**, and requires excellent skillsPilotsOperate. InDronesToday, with the rapid development of unmanned and intelligent, it has become a new direction of developmentU.S. militaryHuge investments have been made in the development of the so-called sixth generationBombersThere is still uncertainty about whether it will be able to evade interception by advanced radar systems and hypersonic missiles.
In today's international security situation, all countries are strengtheningMilitaryThe construction of strength strives to be inMilitaryA breakthrough in the field of technology. The United States asMilitaryStrong country, inMilitaryOverwhelming advantage in terms of budget. However, facedChina and Russiaand other competitors with rapid developmentU.S. Air Forceofb-21There are many challenges and uncertainties. With hypersonic missiles andDronesThe rapid development of technology, traditionalBombersWhether or not it can adapt to the current complex and changeable conditions of war has become a question worth pondering and considering. It must be recognized,MilitaryThe improvement of strength does not only depend on the performance of a single fighter, but also on the wholeMilitaryStrength improvement and reasonable planning. Only with the support of comprehensive forces and the coordination of tactics and tactics can we achieve victory in modern warfare.
