Even as a layman the F-313 looks wrong in every way. The wings look too think, the pilot looks like he is sitting on rather than in the cockpit, the engines don't appear to have exhausts, the engine intakes are too small and look like they are obstructed by the fuselage, the FLIR looks like a last minute add on which would detract from any alleged stealth characteristics that the plane is supposed to have, the fuselage looks too wide and out of proportion compared to the wings and canards. Does the front under carriage even have doors? As for the downward sloping wing tips, how can they be aerodynamic in any way? I'm sure that they would add drag as well as making the plane very slabby which would mean larger radar returns when seen from the sides? Was it even taxiing under its own jet power as there didn't appear to be much in the way of haze coming from the exhausts. Why have twin tyres on the front undercarriage if this is supposed to be a light weight aircraft. Lastly what benefit is stealth for what is being described as a lightweight CAS aeroplane?
