What if they turn out to be ours?
You asked about if it was our enemies, which it is not;
we know this because if the Chinese or Russians or Iranians had this tech they would have used it on us and the other western democracies already.
Your asked about if it was alien tech, maybe it is but I
very much doubt it since there is not a shred of evidence
that ET’s exist, the only evidence for intelligent life
anywhere in the universe is right here on Earth. Of
course maybe this tech is the evidence of alien life,
we’ll have to wait and see.
The one scenario, which is the most likely according to Occams Razor, that you didn’t ask about is, what if it’s our technology?

That question has been asked and answered from the get-go. If they were our Black Ops, the Pentagon would have told the Navy to shut their yaps and would have advised the Senate Select Committee on Intel what was going on in private.
