The B2 bomber is the only stealth bomber in the world. Why has no country been able to imitate it?

The current U.S. B2 bomber is the most advanced bomber with the best stealth performance in the world. In the 22 years of service, no fighter can compare with it. It even makes the U.S. military feel like it is alone and seeking defeat. As for the fact that it has never been replaced in the past 22 years, no newer and upgraded version has been developed. Because B2 is now beyond comparison with other countries. Except for the United States, other countries have no idea of ??imitating it. So why don't other countries develop or imitate such an advanced fighter jet?

Other countries are salivating over the B2 stealth bomber, especially the Russians. However, it is not easy to manufacture a stealth bomber similar to the B2. This not only tests a country's aviation heavy industry manufacturing capabilities, but also tests the aircraft design and manufacturing experience. More importantly, it requires a large amount of capital investment. Looking at all the countries in the world, it can be said that at least 10 years ago, no country could match the capital and investment of the Americans. It was impossible to imitate the B2 stealth bomber or even create a similar one.

The aerodynamic layout and appearance are difficult to design. Previous bombers, such as the B-52H and Tu-160, had radar reflection signals that were too large to avoid radar detection. After long-term research and demonstration, American scientific researchers finally determined that a flying wing layout with a flat fuselage and no vertical tail was the most suitable, and the engine inlet was designed in the upper part of the fuselage.

However, the Americans figured out how to maintain a stable flight with such an aerodynamic layout through a lot of calculations and tests. Other countries still need to conduct a lot of tests if they want to design similar stealth bombers. Just look at B -2 The appearance is only for reference value.

The cost of developing the B2 was too high, and the high performance of the B2 bomber was forced by the situation at the time. But now bombers pay more attention to the ability to strike outside the defense zone. Even the United States has begun to develop the B21, the next-generation bomber of the B2. Therefore, there is really no need for countries to spend huge sums of money to imitate this ghost bomber.

Insufficient demand. The B2 is a strategic bomber. Except for a few global powers, it is of no use to other countries. What's really great about the B2 is that it can perform intercontinental strike missions. For medium and short-range missions, it's like killing a chicken with a knife.

At present, among the three countries, China, the United States and Russia, the United States already has B-2 and B1B, and the new generation B21 is already under development, while Russia also has Tu-160, Tu-22M, etc., and there is no demand for strategic bombers. So high. Only China has its old H-6, so it urgently needs strategic bombers like the B2.
