I think the USA has ~3ish airframes/systems that are roughly in this category:

* The Kratos Valkyrie with the USMC in a SEAD role

* Anduril (YFQ-44) and General Atomics (YFQ-42) are battling it out for the USAF's CCA Increment 1 contract (we're apparently supposed to get a decision on that this year) - with Increment 2 probably getting spun up pretty soon

* USN has the Boeing MQ-25 as an drone tanker... once that gets up the speed, I'm fairly certain it's going to morph into something strike capable

Elsewhere, Boeing Australia's Ghost Bat seems to be doing well as well.
