I bet at the very least, the US govt and other large govts have some way of knowing whatever is actually possible TODAY and have plans in place to make sure whenever it is practical, they get the very first useful ones built.

I would guess they probably don't have any actually useful and in production right now, but they probably have a few secreted away in development, so they will be ready to put them to use if/when they do become useful.
