How hard is the new strategic bomber design? The Americans told you.
As far as the United States is concerned, as the most powerful country in the world, military scientific and technological strength covers the world, and it is necessary to have technology and experience, just take the strategic bombers they are currently in service, no country in the world dares to say that he is more powerful than the United States, and the United States is now in service with B52, B1, B2; These models have been the products of the previous decades, and even the B52 has been in service for nearly seventy years, even if the world's only full stealth bomber B2 has been in service for more than forty years, it is reasonable to say that it will be retired, the equipment parts have aged, the system has been too backward, can not keep up with the requirements of the new era of military intelligence, of course, the Americans have long recognized such a point, so they are also updating, B21 new strategic bomber is produced in this context, However, this concept has not been proposed in the past two years, the American B21 new bomb has long been proposed for nearly ten years, and the prototype has also been produced, but it has been postponed until this year to start saying that it will be test flight, why has it experienced such a long time?
The answer is hard, too hard.
Americans are not unintelligent, nor are they unskilled, Americans have never slammed the door on the design of military equipment, and Americans will not fail to pay for things that are related to national security.
What's the hard part? Is the concept of the new bomber is not the concept of the B2 at that time, they pursue a higher level than the predecessors, difficult in positioning, the Americans want a bomber whose price is not very high, the technology is very advanced, the bomb load can not be less than the predecessors, the range can not be too short, the speed is supersonic, the intelligence is very high, these collections, it becomes like their fat electricity, the requirements are very high, but the manufacturing is not dominant.
This year's prototype test flight is definitely the biggest thing that military fans around the world are most looking forward to.
Hard, make it too!
