While the shape is somewhat similar to a draken or an f-16xl with a cranked delta wing. There doesn't appear to be a vertical stabilizer. It's possible that this is an existing aircraft modified to test alternate aerodynamic configurations similar to the F-15 STOL. Alternately it could be a flight-ready version of one of the tailless NGAD designs.
