B-2 stealth bomber is called the product of alien technology.

As a masterpiece in the history of human aircraft, the B2 bomber is not only a milestone in the field of bombers, but also the strongest means for the United States to demonstrate its military technology. As the first and only stealth bomber, the military deterrence of B2 is unimaginable, and even the military deterrence of B2 bomber far exceeds that of American aircraft carrier formation. Although the B2 bomber is very powerful, it also gives birth to another problem, that is, the B2 bomber has so many advantages, why don't other countries copy it to improve their national defense capabilities? Today we will talk about this problem.

As a stealth fighter, B2 bomber spent as much as $2 1 100 million on research and development in 1997. If this value is converted into today's dollars, it may be more than several times. It can be seen that the US military was determined to engage in stealth bombers at that time. Although it was really developed in the end, the cost of the B2 bomber was too high. Even the United States with deep pockets only made 2 1, which became one of the thresholds that B2 could not imitate.

Secondly, only a handful of countries can build long-range strategic bombers. At present, only China, the United States and Russia can do it. Among them, China's long-range bomber has just started, and Russia has just inherited the legacy of the Soviet Union and just resumed the production line of Tu-160 long-range strategic bomber. Therefore, even if Russia wants to copy or imitate American B2 bombers, it must first improve its strategic bomber production line. Without a perfect bomber military system, it is very difficult to falsify. At the very least, it will not be as simple as imitating firearms, and even the cost may exceed the cost of B2 long-range strategic bombers.

The most attractive part of the B2 bomber is its unique flying wing layout. This layout design is very exquisite, and the requirements for design indicators and risk control are very strict. At present, the only country with this research and development capability is the United States, and this technology has never been made public. Therefore, if you want to copy, you have to steal one or shoot down one before you can disassemble it. This is obviously unrealistic.

In addition to layout, the painting of B2 long-range strategic bomber is also a difficult problem to be overcome. As we all know, the biggest advantage of B2 is stealth, and stealth coating needs the technical participation of many fields to complete. At present, many countries are helpless about stealth coatings, which has become one of the reasons why it is difficult to replicate.

In fact, the cost of a stealth fighter like B2 1997 can reach an astonishing $2 1 100 million, which shows that every part is very valuable and needs the cooperation of many fields to complete. Therefore, although imitation seems easy, it takes more than ten years or even decades to achieve the functionality of B2.

Apart from the technical difficulties, the problem of B2 imitation is actually easy to understand.

For many countries, the long-range strategic bomber is just beautiful and not easy to use, especially for small countries. Spending billions of dollars on such a thing may add up to a year's GDP, and even the pot can't be opened. For a big country, it must be its own superior weapon, and for a strategic bomber, weapons are definitely good weapons, but it is obviously unrealistic and meaningless to waste manpower, material resources and financial resources to imitate them. What's more, if the strategic bomber was really that important, then Russia would have done it long ago. Why do people mainly develop missiles? In fact, if you think about it carefully, you can come to the conclusion that B2 can only be used under very few special circumstances, so other countries will not bother to copy it at all, let alone regard it as the main weapon.

More importantly, at present, missiles are very powerful. Although B2 has certain stealth capability, no one can say for sure whether it can remain undetected by the enemy in the face of today's high-tech radar equipment. If you are really discovered by the enemy, a few missiles can crash you, which is unimaginable in some countries. After all, it takes billions to develop a thing, and the probability of being destroyed is so high. It is better to invest money in developing more realistic missiles and fighters.
