Yeah, that's just a mock-up, and it won't
end up as a real fighter.
While Iran has indeed competent engineers, skilled workers, (some) R&D and industrial base, this one is just... preposterous.
Btw. Is there anyone else, that thinks that this F-313 - esp. it's front part with intakes - resembles a bit "F-19 Stealth Fighter" from the old computer game by Microprose, or I'm the only one old enough to remember that game?
