Say what you will about the airworthiness and politics of the F-313, I like the lines of the craft. Anybody want to make an add-on?
Also, a bit seriously - I don't think this concept is scaled at all. It is not a F-22/F-35 wanna-be. I could see the idea of this being mass produced as a low-tech, moderately stealthy and small fighter, designed to get in close with large numbers against a technologically-superior fighter force. Heck, why even bother putting active radar on the things? Just give it a compass steer and a receiver so they know when they are being painted.
If they are attacked with high-technology fighters that can engage N targets simultaneously, send up N+1 of these things and get them in close enough, fast enough, that several will survive to get into gun range. Once in close a smaller, more nimble jet has a distinct advantage over a big F-22/F-35 missile platform. It would be a counter to the stand-off concept inherent in Western 5th generation fighters.
This is similar to their naval doctrine of using lots of small vessels. Want to take out a U.S. carrier? Send *lots* of small boats, each with a rudimentary anti-ship missile, and saturate defenses.
