On December 2, local time, at the 42nd Plant in Palmdale, California, USA, the first B-21 "Raider" stealth bomber arrived as scheduled. After a black singer's affectionate singing and B-52 and B-2 bomber flew over his head in turn, the curtain covering B-21 was slowly pulled open.
The curtain is opened
That's it?
At first glance, the B-21's wings seem particularly long, which should exceed B-2, which has a bit of the RQ-180 large flying wing drone, which shows that it still regards range as a very important indicator. Global flight and global arrival are the bottom line for the US military to develop stealth bombers and are also the unchanging operational standard for the US military in the future.
wings are indeed very long
Comparing with B2, take a look at
Secondly, the opening of the B-21's air intake is much smaller and narrower than that of B-2. This is obviously to maintain the stealth performance on the front of the aircraft. From this, it can also be seen that B-21 has more pursuits in stealth design than B-2. The stealth level of B-2 is already very impressive, and B-21 is more likely to surpass B-2. The outside world speculates that the B-21 will most likely use two afterburner models improved on the F-135 turbofan engine. If it is true, the intake of the two engines is indeed easier to deal with than the 4.
air intake is very narrow
B2's air intake opening is relatively large. After all, it has 4 engines
3. Overall, the appearance of the B-21 is not surprising. The previous various imagination pictures on the Internet were quite similar. Even the two narrow and long inclined windows on the side of the cockpit are basically the same as the previous imagination pictures. Regarding this oblique window, the outside world cannot understand its purpose. Many people have imagined many high-tech words to describe it, but judging from the official debut, it is likely to be used to increase the pilot's lateral vision. After all, the wings of the B-21 are very long, and there are more than once or twice cases when the US military aircraft shook the wing tips by buildings during the taxiing of the airport.
does have oblique window
This figure is still very accurate
According to the latest public news, the unit price of B-21 is US$700 million. Although it is more expensive than the estimated US$564 million, if it can be achieved, it has improved more than a little bit compared to the B-2, which is worth US$2.4 billion in 2009. Therefore, the equipment volume of 80 to 100 aircraft is not just a matter of talking about it. Of course, mass production is also conducive to controlling costs. Judging from the continuous decline in domestic purchase prices of the US military's self-used version of F35, we really cannot underestimate B21.
can't be underestimated? The appearance of
B21 only showed a frontal face, and even the hangar was not launched. Nog cunningly concealed its side, frontal and downward angle, indicating that the United States has a strong sense of confidentiality and military transparency urgently needs further improvement. Of course, it is also possible that these angles have not been done yet. But no matter what, the pressure now puts at 20, and wait for our "water molecule" to sweep it to death.
Now the pressure is 20.
Interestingly, not long before the B21 was unveiled, the US side's "2022 China Military Power Report" focused on the focus not on the H20, but on the large number of mentions China's suborbital bombers, and used three "bests" to describe this intercontinental strike weapon that breaks the existing rules of the game: the longest flight time, the farthest flight distance, the fastest flight speed, and the highest speed, and said that its maximum speed can reach Mach 19.
borrows the picture of the mother machine of the Tengyun project.
Although many people regard it as a soft article for the Pentagon to ask the US Congress for budget, they did have similar operations in the past, but judging from the current aerospace technology and the development of hypersonic aircraft , subsonic stealth bombers such as B-2 and B-21 are indeed smaller and smaller in the field of playing their roles. In the future, it will definitely belong to suborbital bombers and transatmosphere aircraft .
The future is a space-to-space integration. Hypersonic
Although the US description is outrageous, it is not all about catching wind and shadow. Judging from the successful tests of my country's two reusable test spacecraft and a suborbital lift-body aircraft, the breakthrough in subsonic stealth bomber technology has reached a moment before dawn. Even the development of the sixth-generation aircraft may take the route of a space-to-space integration and hypersonic. The B-21 is now publicly unveiled. When the test flight is over, mass production and service is over, it is likely to be outdated and become the last struggle before the fall of the US air hegemony.
