Maybe it's air launched ? Foldable wings would make it way more manageable.It looks to me like a "diamondback" style wing like what we've seen on the SDB-I before.
I wonder how far the wings can fold out -- whether the model depicts it at maximum extension or moderate.
I suspect if it was folded inwards fully the main wings would be swept much further back.
The overall geometry of the drone is also a bit odd, it's not clear to me if it is likely to be a relatively small sized UAV or something larger.
