No point to J-79, like the J-85 it’s a 1950’s engine.

Neither can be used in a future Iranian fighter jet.

we cant jump just like US that built the thing we have too its a learning process doesn't mean iran is going to use it in numbers the goal is to build RD-33 turbofan for mass production

Could they possibly be used in a larger future drone platform of some type?

Exactly. Both J-85 and J-79 may be used by Iran NOT in manned fighters but in UCAV supersonic fighters.

I'm sure Iran is developing its own turbofan engines (for manned & unmanned aircrafts) but till these projects are mature and finished Iran maybe is working in these older engines for supersonic UCAVs.

The thrust-to-weight for such unmanned platforms would be far better than for a manned one (a drone does not need any human inside nor a vital cell for the health of the pilot, so the save in weight is BIG).
And due to this loss of weight the range, speed, agility... would be better in the supersonic UCAV, related to a manned fighter with these J-85 or J-79 engines.

I'm sure Iran has followed this path years ago. The results are not public (are confidential yet) but drone tech in Iran is TOP WORLD, so...

Other options would be non aircraft related such as a marinised variant for naval use like the lm1500 or also commercial use for gas pipeline compressors.
The main military option would be a complete reengining of the entire f4 fleet with locally manufactured brand new improved j79s fitted with new technologies such as fadec,but whether the airforce would actually be capable of implementing a program like that is anyones guess.....

RD-33 was going to be used in 2003 Shafaq. 20 years later it’s obsolete as well.

These engines are merely to train the workforce and keep them employed till an alternative engine is able to be reverse engineered.

Unlikely as for drone that large to require a jet engine you are probably looking at a stealth frame or LO. In which case both J-79 and J-85 are not suitable for a stealth UCAV. Future stealth drones will likely be as big maybe even bigger than F-5 and F-4.

For smaller UAVs Iran already unveiled a drone jet engine that can be expanded on.

So you really aren’t solving the powerful engine problem.

Stealth supersonic UCAV would be the 2nd step. The 1st step would be supersonic UCAV.

F-15, F-14, SU-30, SU-35, F-16, MIG-31...all of them are NOT stealth. And we are talking everyday in this forum (and previously in our dear and missed IMF) about Iran's needs in terms of Air Force, and purchasing SU-30 SM2, SU-35 etc etc which are NOT stealth.

So a supersonic UCAV with a J-79, with an AESA radar and armed with BVR AA missiles is not a silly thing as the 1st step to renew Iran's Air Force.

The manned fighters and/or stealth fighters would come in 2nd step.

did it fly yet?

Only in an animation.

Heres an oldie...

Technicians installing the guidance section on a GBU-10 Laser Guided Bomb.
Does anyone know how many of these were actually supplied or if they were used in any numbers during the iran-iraq war?.

Iran is purchasing SU-30 and SU-35 to defend its airspace NOT penetrate foreign airspace. Thus stealth is a lot less important when fighting on your home turf.

A jet powered UCAV should be stealth if it’s main goal is to penetrate foreign airspace and assist with bombing missions (look at Chinese next gen drones and Russian for example).

Or else if you build a large non LO or VLO drone it’s just gonna get shot down when it approaches enemy air space. Unless your enemy is a bunch of insurgents or like Armenia operates a 1970’s air defense network.

this is second generation Saegheh - you should see its 5th generation.

as I know we just had maverick missiles which was guided. rest were unguided bombs.

IRIAF has had GBU-10 Paveway laser guided bombs and Laser designator pods for its F-4 fleet dating back to the IIAF days. Laser guided bombs were used early on in the war.

so where are the pods now?? if you mean the tls-99 it's a RE French pod we got our hand on it when mirage f1s deficited to us.

My mistake. IRIAF F-4Ds were supplied with AVG-9 Pave light Laser designator that gets installed in the backseat of the cabin and operated by the weapons system operator, not a pod.
