just like the US space program that was kickstarted by stealing Soviet design, and the nuke program and the air force that were created on the back of anonymous Chinese scientists, the AUS (America United States) have to wait for either Russia or China to come up with something for them to copy.
Notice how after the B-2 and F22 everything they made has been shitshows after shitshows. That is because the end of the cold wars resulting in mass repatriation of Chinese and Russian scientists to their motherlands. Also, the American drank their own coolaid and started to replace Chinese and Soviet born scientists with American born and Pajeets and DEI.
