“Defense tech” should not be a capitalist for-profit venture. The incentives are all wrong. The business model is basically “milk the government for as much money as you can get, over the longest possible time period”, which is never a good business model for incentivizing efficiency or innovation. That is how American defense manufacturing got so slow and costly. It’s why America struggles to produce something as simple as cheap artillery shells at scale: simply not profitable enough. Much more profitable to sell fancy tech at $3m a pop.
