I think there are some recycled concepts from Star Wars. Some other parts are specific upgrade projects that DoD has been wanting to do anyway, that are probably worthwhile. I think the remaining chunk will be shoveling money to grifters for pie in the sky Real Genius projects that never work.

I haven’t seen anyone seriously talking about actually using Iron Dome components for North American air defense. That’s a good thing. The geography and threat profile is completely different.
