With such a lack of control surfaces it can’t be too maneuverable.

I imagine that the level of stealth/ profile that they are going for would preclude the need for maneuverability.

Not saying that is the case, nor agreeing with the logic, but I am going to assume their are enough former military pilots on the payroll at Lockheed that this had to have come up.

I would think it would require the use of a directing nozzle to make the thing handle at all.
