Then some Senator will come in and question the program if relationships with the Chinese improve and it will get curbed at a few dozen jets with ridiculous operating costs.Probably above 200 million USD a piece. This will put developing countries with their 4th gen fighters completely out of race to compete in air warfare. China is the only country that can offset this kind of advanced tech.
Instead - it could follow the Tempest model and be modular so that the costs are kept manageable and as technology gets at scale the costs don’t change so 350 NGADs could be fielded.
