Flapless UAVs have been designed and flight tested for a long time on both sides of the Atlantic, say for years.
This airframe is certainly not a "world's first".

Vector thrust control is also an old technology. Everyone is working on boundary layer control at this stage. Once again there are prototypes flying on this technology on both sides of the Atlantic. No mechanical flight control, no vector thrust, no rudders, pneumatic backup so that the plane can be controllable for a certain period of time in case of engine failure...
So the airframe shown on the video is not only obsolete, but amazingly expensive redarding the technology used.

P.S: If you look carefuly, you'll see some of these prototypes here ( completely in-house designed ):
