This is technically very impressive, but...
It performs the same job as a sam or aa gun, at a much increased price I would bet. And why is there a need to return to base? Then it needs to be refueled. You can also see when launched it sheds some covering, so returning to base does not mean it is operational again, it needs to be reset.
And that is in general the problem with US armament systems these days. Very impressive but way too expensive.
