>>Iran releases pics of its Qaher 313 light weight twin engine 5th gen jet. The following pics are from its taxi tests. Its speculated to use 2 J-85 (Iranian version) Engines.
2 J85, Factoring the size at best this is a demonstrator. but one that likely will be problematic.
The J85 Turbofan was used in the F5 Freedom fighter, one of the Birds the Us sold Iran before the Revolution and one they have reverse engineered, the J85 was intended for Drones it's a very light weight easy to fix but low power turbofan. Perfect for nations with a limited industrial base. Unlike the 2013 mock up this has a properly sized cockpit. but It's not no fifth gen.
It's nose cone is to small to house a proper fighter radar beyond the small AN/APG69 or iranian clone there in. the intakes are dubious as is the wing the fuselage is to small for more than maybe 2 small Close range Air to Air missiles and that's being generous. Although it has a Flir turret I doubt it has the ability to actually use it in a conflict. there is a single dorsal antenna likely the Radio.
It may be stealth-ish... But Have blue was stealthy and it was not a fifth gen.
If this flies and is low observable that are 2 parts of the fifth gen category.
It needs to carry internal weapons, this is to small
It needs sensor fusion with signature reduction, I doubt they have that at best They might try and use the FLIR as an IRST but how effective it will be? That Flir looks like a commercial model not military.
The Iranians Claim that they designed it to be extra stable in flight this allows them not to need fly by wire. Instability in flight is a hallmark of 4th and 5th gen fighters it allows maneuverability and demands Fly by Wire.
