Go check out why Lockheed Martin can't build a new F22. It is also difficult for the US military to repair ships now. Technology is indeed leading, but it is a long process from laboratory to mass production. The biggest problem for Americans now is mass production. The first is insufficient human resources. With a large amount of capital playing in the financial industry all year round, the decline of the real industry has led to fewer and fewer skilled workers. The second is a blind spot in mass production, called technology loss. Both the United States and Russia have encountered this situation. The company or drawings of a certain key part were lost. Why was it designed like this at the time, and why was it made like this? Later, people could not figure it out just by looking at the drawings, and they could not understand the original designer's ideas, so they could not connect the pieces at all. It doesn't mean that I can just copy the drawings directly after understanding them. If you re-engrave it, you won't be able to upgrade it in the future.
