SpaceX will sell the Air Farce the rockets. The AF launches their gear into orbit. SpaceX has nothing to do with it more than to get paid for the hardware and some support personnel who will have to have security clearances.
These aren't just slightly confidential, state of the art spy satellites is top secret business. They'll be worrying that a SpaceX employee can plant something to steal technology, reveal capabilities, damage or compromise the satellite once the payload is installed. I'm guessing you need just a microscopic amount of C4 if it can hook into the antenna and wait for a self-destruct signal so that when you need them the most they go boom and the screens go dark.
