How did the US military coat the F22 with stealth coating?

On this issue, I dare to say two words:

As the fifth generation supersonic cruise fighter, the F-22 of the US Army needs at least five anti-radar coatings, and 60% of this coating is silver. At the same time, after a long flight, once the coating is maintained or replaced, it is necessary to knock down the previously coated radar-proof coating and repaint it, which costs millions of dollars each time.

Of course, these removed waste paints can also be recycled, turned into other materials and sold to related industries to make up for some military expenses.

But if the subject asks, "How did the U.S. military paint the stealth coating on F22?" I guess if you want to know the real answer, you can only ask the US Department of Defense. .

The public information will only tell you that the painting operation of F22 was completed in a special spraying workshop, but will not tell you the specific process, which involves the core military secrets of the US military. The complexity of the military industry system is beyond your imagination and cannot be completely summarized in one sentence.

In addition, I would like to add that in August of 20 16, the US Department of Defense signed a new maintenance contract with Loma Company, with a total price as high as $6 1 10,000, which is only the cost of building a brand-new "maintenance assembly line", not including the labor and technical costs involved, and a series of follow-up projects such as material research and development.

Therefore, I can't give you a definite answer about how the US military put the stealth coating on the F22. I can only tell you that as a fighter of the fifth generation, no matter what the F22 is, even if it is a fire, it will burn real money.
