North Korea had 2 successful LEO insertions with Unha-3 aka Simorgh. In 2012 and 2016, soon they will use new SLV or adapted from ICBM. Considering frequency of ICBM launches and successes these had.... ...DPRK could have capacity to insert 12 LEO satellites a year. If they repurpose Hwasong-15...

Keep kissing and licking dirty American and Israeli soles.

So not fan, spools, turbines, compressors... Yes, alternatively new turbofan could be developed to fit inside engine bay. J85-GE-21 is simple 1 spool 9 compressor 2 turbine compact turbojet engine. Very much possible to develop turbofan of comparable or greater thrust.

Rocket engines do not operate for hours. Non-3D printed at most do 4 or 5 minutes. Turbojet engines in fighter jet do hour or two. Turbofan can do 24 hours in an UAV/UCAV. Also 3D printed geometry is questionable.

Simulations can not replace real world for testing of components. Neither can be relied on 3D printers for anything that crucial. You place too much faith into wishful shortcuts. For those to have any worth they need real world data as reference point. What I suggest would provide such for...

Except it is not in any way possible because you can entirely design new components for next generation fighter jet with only compatibility mounting system/socket for F-14. Later on that can be changed for a better design if there is one for next generation fighter jet, in mean time development...

Your reply is utter nonsense and embarrassment to any intelligent lifeform on this planet. F-14 is disposable so why lose a brand new aircraft by testing new engine along new radar as an example. China conducts tests of new radar and engines on older aircraft until they are used on newer...

F-14 Tomcat is not useless as it has large nose and large turbofan engines, it can be used as platform to test new radar and jet engines. RCS of F-14 is 25 that is same as F-15E and former can have just as potent radar as latter. In case Iran manages to develop F110/AL-31 tier engine then range...

Current wing of Yasin isn't strong enough while a new one could be made, though Yasin needs a thorough redesign in case Iran upscales Jahesh to FJ44 output of 16 kN. Since fuel consumption rate would be cut by nearly a 3rd compared to J85 turbojet engine and allow reduction of fuel tank size to...

Iran could have developed their own Yak-130 equivalent easily. By upscaling and improving Jahesh-700 to 1600 kilogram force thrust. Then by replacing J85 turbojet Yasin can be improved to a high degree. Though would essentially turn into a new aircraft. Since FJ44 equivalent turbofan consumes...

Kowsar could be made as effective as F-14 by making these choices: - no automatic cannons on the aircraft. - new nose for the aircraft to house larger radar. - new air to air missile that at most is 500lbs in weight. - with modern manufacturing should allow new AAM an AIM-54 range. - landing...

Resolution of satellite imagery is not that great to make a judgement about those Su-25.

North Korea placed priority on its military industrial complex hence other civilian sectors do not get nowhere as much investment by the state.

Considering that North Korea produces turbopump comparable to RD-250 in size while operating nearly 60 percent longer. At very least R-25-300 turbojet could be potential engine or of turbofan then perhaps comparable thrust to RD-9 turbojet. Although that could be near full scale decoy to...

In theory yes, but at end of the day this makes sense for countries that are very large or when no one is willing to sell them military aircraft or anything else.

So did South Korea with American fighter jets, them and China gained knowledge through manufacturing of such and latter had original designs for decades. There was J-12 that basically was a partizan/guerilla style fighter jet that to western world equivalent was F-5 Freedom Fighter before Tiger...
