It requires a massive investment in research and development of advanced aerodynamics, material science, supply chain, skilled mechanics, etc. You just don’t pop out a plane from a group of engineers like we did during WW1. Creating a fighter jet that is capable enough to defend against today’s adversaries will require a couple decades of investment to start from scratch. And yes I know you probably think that we can just use the knowledge already available from previous fighter jet programs like older American jets but even if they had de-classified designs they still don’t have the supply chain and technical experts to pull it off in a few years.
