Well not surprising. National security/national infra is involved. Private companies will not fund/build nukes, missiles, aircraft carriers, fighter jets etc if there aren't certain guarantees from the State. Not just in US, all over the world.
Think about what would have happen if the Manhattan Project was run by the private sector. As soon as national security/infra becomes a risk the state will start getting more involved whether the private sector wants it or not.
The banking system/telcos/utilities in most countries have the State providing some kind guarantee to keep the lights on in case something unpredictable happens.
